I love this shot because it shows the poppies lining my walkway all the way back. Below the Showy Penstemon is a monkeyflower bush. And there are still more flowers to bloom this season!

Spectacular Showy Penstemon (Penstemon spectabilis)
It may not seem like it looking at these photos, but I actually have had trouble keeping Penstemon spectabilis alive. I’m am almost sure the problem is too much water. I mean, they look lush and as if they want water. But, I don’t think so.
I took these shots this morning because I liked how vibrant the color was with the sunlight slanting in behind them. The time of day makes the flowers seem to glow! Then I took a couple close-ups because the flowers are so interesting to look at.
Plus, knowing me, I’ll kill this one soon overwatering it.
I planted this penstemon in Fall of 2016. So it has been in my garden for just about a year a half. It was very small when I bought it, probably six to eight inches. It is now pretty close to 4 feet tall, I’d guess now.

Sky Lupine (Lupinus nanus)
I got a few packets of wildflower seeds from my favorite nursery, Grow Native at Rancho Santa Ana Botanical Gardens in Claremont. This lupine is from those seeds. I only had poppies last year. I’m enjoying watching the wildflowers grow this year.
Part of my plan is that these wildflowers will help crowd out weeds. It has been a struggle to eliminate weeds from the garden. There was a time when the entire yard was all weeds. I have tried using mulch and removing weeds by hand. I will admit to using some Round Up but it’s difficult to use around my plants.
Wildflowers should help by both crowding out the weeds and also by helping establish the underground microorganisms that feed the native plants.
In the meantime, they are beautiful to see.
Baby White Sage Sneaks In
Above, you’ll notice the very large White Sage (Salvia apiana) at top left. It’s about 5′ tall. When the flower wands sprout, it will touch 7′. But look down and toward the center. In the bottom right corner is a California Golden Poppy (Eschscholzia californica). Just above and to the left is another smaller White Sage. Two branches sticking up about a foot or two. I didn’t plant that sage. I’m assuming it is an offspring of the larger plant there! And if you look closely to the right of he larger sage, there is a Penstemon centranthifolius (or eatonii, I’m not sure which it is) that has also sprouted there.
I love that new plants are growing in the garden that I didn’t plant myself. I take that as a sign that things are going well for those plants.
Spring: 2018: Back in the garden
A friend suggested posting something each day, even if it wasn’t much. I am going to try something similar. I have been very interested and amazed to see the changes in my garden. Spring brings on new growth, blooms, and color. And this is the third year many of my plants have been in the garden.
First they sleep, Next they creep. Third they leap!
This is, I am told, an old adage among gardeners and has mostly been true in my experience with this garden. Most of my plants barely grew at all the first year. Little buds here and there.
So, this being the third Spring, I’m seeing some good growth in many places.
I’ll try, if nothing else , to post a picture and a sentence or two about it. At least 3 per week. More if possible. Why? I don’t know. Why not?
I had some physical limitations get the best of me over the winter. I’m limited in some activities, like lifting heavy objects or bending over. That makes garden chores more difficult. Or expensive. It cost me $60 for my son to help me weed this month. I don’t mind paying him. He’s doing a lot of work and he does well at school. So, he deserves some pay. I could not have done it without him.
Please enjoy these pictures from my garden in the last week.
California Poppy “‘Mahogany Red” from seed.
Below is my stream area. White Sage, Upright Rosemary, California Morning Glory, some succulents, Jelly Bean succulent, Firesticks, and some other succulents. I’m not so knowledgeable about the succulents, I admit.
Above, a wide shot of my garden showing my California Buckwheat, Eriogonum fasciculatum. There’s a big bunch up front, behind that, and another to the right. Up front is also Penstemon “Margarita BOP”, some black sage, white sage, Bee’s Bliss sage, ceonothus, manzanita.
Below, Penstemoncentranthifolius ScarletBugler with some buckwheat creeping behind it. I didn’t plant this. It grew from seed from another plant!
California Morning Glory Calystegia macrostegia and a California Golden Poppy.
Below, some wildflowers from seed I got from Grow Native nursery at Rancho Santa Ana Botanical Gardens. Also, I think there’s a Margarita BOP penstemon at the bottom. I swear I thought that thing died. Note to self: ignoring plants seems to help them live after a point.

Fall Planting Season is Here!
On October 21st, the Rancho Santa Ana Botanical Garden’s nursery, the Grow Native Nursery, and my favorite place to buy plants, had their annual Fall Planting Festival. As a member, I got to go in at 8 a.m. with other members and pick out plants early.
I had done my research. I lost a good number of plants this summer. I lost four “Winnifred Gilman” Cleveland Sages, several White Sages, a couple Penstemons, all four or five sticky monkey flower plants, a “Canyon Sparkles” manzanita, and a Desert Willow. I might have left some out, but that’s what I’m remembering now.
My research was to find the plants that are not only native to California, but native to the same kind of area in which I live. The site for Las Pilitas is a treasure trove of information. There, I learned that my area is a Chaparral plant community. I had previously thought it was Coastal Sage Scrub because Las Pilitas said my zip code was in that area. But, I live in the “Inland Empire” a region characterized by heat and wind and little rainfall. We are in the foothills of the San Bernardino mountains but my elevation is about 1500 feet.
So, although this might be a Coastal Sage Scrub area, the heat and wind means the plants need to be able to put up with all of that. And, as I look at the areas of land that aren’t developed, it most resembles a Chaparral area. The Coastal Sage Scrub (CSS) is a cooler area. And, the plants get a significant amount of fog that drips on them and is a source of moisture, while the Chaparal plants have to deal with more heat and little to no fog. The Chaparral community gets around 15 inches of rain per year, maybe slightly more than that.
Accordingly, I used Las Pilitas to find plants that do well in that environment. There’s some cross over between Coastal Sage Scrub and Chaparral among plants.
Some of my sages were good, Black sage and “Allen Chickering” sage for example. Ceanothus and many manzanitas are ok, too. Diplaucus monkey flowers are okay, but not Mimulus species. But there were some plants new to me that were suited to the Chaparral community such as Toyon, Coffeeberry, Lemondade berry, and flannel bush. I’m really looking forward to seeing those grow up. They are great for birds and we really enjoy having our winged friends in the yard. (We get visited by finches and sparrows (of course, probably the most common birds around here), but also mockingbirds, black phoebes, and hummingbirds. There’s also a big flock of pigeons. Recently, scrub jays have been coming around and I saw a Western Meadowlark.)
I tried hard to choose plants that deal well with heat and dry conditions. I made my list, considered where I would put such plants, and I picked out 47. It was a lot of plants. In fact, at checkout, I had no less than three people say, “Is this all one order?” Because it was unbelievable that one person would buy so many plants.
There seem to be two schools of thought, for planting California natives. One group says you should only plant when weather is cool as in Fall or Winter. Late fall is best. I agree with this. But Las Pilitas says you can plant all year long if you want to as long as you are willing to make accommodations for your plants, like watering them.
That being the case, I planted 19 last weekend. To me, it’s better to have a plant in the ground than in a plastic pot. But, disturbing the roots, as planting can do, is stressful to the plants. That’s why planting in the heat can be harder on them.
That weekend and the last week have been hot, though. Very hot. We went over 100 degrees a couple days in a row. And then the wind was awful, too. In fact, the weather was ugly all together. Heat, wind, and extremely low humidity. Also, the high pressure in the atmosphere kept the heat trapped. So, for several days in a row, the temperature didn’t drop below 85 degrees, even at night. Heat, low humidity, high wind, and no cooling at night? Brutal for new plants!
Summer Refuses to Leave
Last year, I watched as a beautiful Grinnell’s Penstemon withered and died over a timespan of about two weeks. It had spread to about 3 feet wide since I planted it, starting from 6 inches high and barely five inches wide. It had bloomed during Spring and looked completely healthy and happy.
Until it didn’t.
The leaves all curled and it took on a sickly purplish color. Then it shriveled and dried up. It was dead. Had I watered it too much? Not enough? Was it getting too much shade? Too much sun? Did it get a disease from the soil? I had lots of guesses but no way of knowing what killed my penstemon. So, I contacted a graduate student who was working over at the Rancho Santa Ana Botanical Garden Grow Native Nursery and asked him what happened. I sent pictures and described as much as I could. His answer? No idea. He said, “If you can figure out why any plant dies then you have answered the million dollar question.”
I guess it makes me feel a little bit better that even someone with a formal education in gardening/botany can be as mystified as I am. But, it’s also a little bit frustrating. How are we supposed to keep our plants alive if even experts aren’t sure how to do that?
I’ve lost several plants this summer. Heat? Gophers? Disease? Too much water? I just don’t know. The casualties (so far, the summer ain’t over…) as of today: two penstemons, three monkeyflowers, a desert willow, a black sage, a ceonothus (that I moved after it sprouted from a seed dropped from another plant), two other ceonothus that I bought, a Jeffery pine, a couple of dudleyas, and a manzanita.
The weather is supposed to be cooling off. Today the high temperature was supposed to be 95. It’s currently 102 degrees in my yard as I write this. That’s hardly cooling off! Then again, we live in the Inland Empire, a region of heat, wind, blue skies and sunshine. And, I just read on my favorite weather blog, Weather West, this has been the hottest summer ever on record. It shouldn’t surprise me, I guess, that the summer just refuses to go away.
It’s a Wet Heat: Unusual Weather This Week
There’s been a bit of exciting weather this last week. And by exciting I mean different from what we usually get during this time of year. Normally it’s hot with clear skies, little to no wind, and humidity around 20%. Hot, dry, clear. Weeks go by with little variation other than if it will be 100 degrees, 105 degrees, 110 degrees, or merely 95 degrees.
Last week we had a couple of thunderstorms pass through! We had actual rain and actual lightning right here. Thunderstorms are pretty unusual in this vicinity. Thunderheads will develop over the mountains 20 miles, or more, to the north, or even further away to the east. Storm cells often form and pass through Temecula, Lake Elsinore, and out near Baker and Needles. They very rarely pass over the Fontana/Rialto/Rancho Cucamonga area. But, this last week we had two days where storms passed right over us, drenching the yard with .07 inches of precipitation. Oh, frabjous day! Callooh! Callay!
Then, we had four or five days of heat with temperatures over 100. Ugh. I’m so done with the heat. It’s hell on the younger plants and I’m forced to water, even when I don’t want to.
My current plan is to water only the youngest plants that were installed this last Fall every other day. Once exception is my Gambel Oak tree. It isn’t a California Native, but rather is from the Utah/Colorado area. It’s drought tolerant once established but it’s used to much more rain than we get normally here. Well, for that matter, my other two oak trees also usually grow in areas that get more rain, too. So, I have been watering the Gambel about three times a week and watering deeply. The Chrysolepis oak and the Wislenzeni oak both are being watered deeply once per week. Lo! And Behold! The Wislenzeni (aka Interior Live Oak) has sprouted new growth of several inches on multiple branches. The Canyon Live Oak (Chrysolepis) also typically gets much more rain but it has not sprouted new growth much recently. It’s sleeping, I guess.
Then, once per week, because it is so hot, I’m spraying the plants down and watering the older plants, too. Well, not the ceanothus plants. They get sprayed but not watered. They hate water, apparently.
The other thing I’m doing is trying to confuse the gophers. I have at least one gopher active in the yard right now. I want to catch him but it has been too hot and I’ve been too tired from work to get in the garden and dig so I can set traps. I think that the gophers are attracted by the water in the soil. So, when I water just the foot or two around a plant, it tells the gopher where the tasty roots are. So, instead, I’m watering much more broadly. The mulch is doing a pretty good job of limiting the weeds so I can water more areas in the yard. This way the soil is wet in a lot of places, not just where the new plants are. It seems to work somewhat. Last year gophers would dig up right where the young plants were, killing them. But, this year I’ve seen gopher mounds where there were no plants at all.
But, I’ve still lost five or six plants to the heat/gophers. Two ceonothus plants are dead and three monkey flowers plus a couple penstemons. I don’t like that. But, maybe that’s just how it goes in a garden. I once counted over 120 plants in my yard, not counting the vegetables in the raised beds. In that case, less than 1% of my plants died. I guess that’s pretty good. I’m still done with all of this heat, though.
Native Plants… So Hot Right Now!
The story of July so far is heat. My Acurite Pro 5-in-1 Weather Center has been recording the temperatures. Here’s a screenshot from my Wunderground weather station app.
The temperature chart shows the daily highs and lows from June 12 through July 12. A month ago, June 14, the high was 92 and the low was 49. That’s a big difference from July 9 when it hit 112 degrees and the low was 72. From what I understand, the really brutal part of summer for my plants is the night time when it really never cools off enough for them. My vegetables, especially, seem to be suffering. I’ve got a drip irrigation system on them now, so they are getting the moisture they need. But, the heat seems to be affecting their production of fruit.
My native plants are adapted to the heat. Many of them go dormant in the summer. While there is variation among the plants, the cycle seems to be that they conserve energy during the summer. Water is pretty scarce so they survive instead of thrive. But, when the temperatures cool down in the fall, they prepare to grow and by the late winter, most California native plants are blooming and growing. For example, my desert willow trees drop all of their leaves during the winter and look dead. But, if you look, there are buds on the branches. When the weather warms, the tree sprouts leaves and grows. The summer is about flowers, seeds, and survival. A few plants, however, especially the younger plants, are still growing! I’ve seen new leaves on some of my manzanita. The white sages’ flowers are all but gone, now, their “wands” browning and ready to drop seeds, but they are sprouting some new leaves, too. But, the biggest story of growth this spring/summer has been my Gambel Oak!
You may be able to tell in the picture above, the two branches that are tallest are completely new growth just this season. Both of them represent two or more feet of new growth! It’s a big jump for a plant that heretofore has only shown inches of new growth in the past couple of seasons.
I have been told that there is a saying among gardeners that “first they sleep, then they creep, then they leap.” This Gambel Oak was planted back in June of 2015, one of the first plants I actually put in the yard. So, in all, it was two years ago, but it feels longer. Patience is important, I guess, with gardening, but it’s hard to cultivate that, pun intended.
The heat has been brutal but looks to be letting up a little. Yesterday it hit 101 but today is suppposed to stay in the upper 90’s and the same is predicted for the rest of week. But, we had multiple days of scorching heat, over 15 with temperatures topping 100 degrees. The heat makes watering difficult. California natives don’t like water in the summer time, mostly. While I’m far from an expert on such things, my understanding is that the native plants have adapted to the heat and the nutrient-poor soil by working with microbial organisms in the soil. These bacteria live on the roots of the plants and they fix nitrogen, I believe, that the plants then take in. The bacteria thrive when soil is cool and moist or warm and dry. But, they don’t like warm, moist soil. Too much moisture in the warm soil kills California native plants and some are more sensitive than others.
For example, I have ceanothus plants that absolutely HATE water in the summer. They even seem to dislike it in the winter, too. The leaves turn yellow and fall off if you water them too much. But, on the other hand, some of the plants do want some summer water, particularly if they are in the first or second summer season. I have this really great book by Helen Popper titled “California Native Gardening: A Month-by-Month Guide” in which she writes:
Do not overwater. In most of the state, summer water wreaks havoc with life underground. Not only does overwatering in the warmth of the summer promote the growth of fungal pathogens that lead to root rot and crown rot, it also harms beneficial fungi that link to their roots and enable them to take in nutrients and water efficiently. These links, called mycorrhizal links, enable the plants to ward off diseases, help them recover from drought, and improve the structure of the soil. The mycorrhizae exist in mature native gardens but they take time to develop in transitional gardens. Overwatering (or overfertilizing) disrupts the establishment of these unseen important relationships.
Overwatering also causes other problems. It needlessly encourages weeds and garden pests, such as aphids and gophers. In the parts of the state where irrigation water contains salts, watering during the dry season also causes salt to build up in the soil. While it is tempting to provide extra water for faster growth, hold off for now. Instead, water the soil deeply for survival, and hose off the plants once a month for looks. Irrigate, if you like, to stretch the natural rainy season forward a bit in fall and to push it out a bit in spring, but use restraint in summer. (Popper 128)
I try to follow the advice. But, we have had multiple heat waves over the last few weeks. I started this post a week ago and the heat is still hitting 100 every couple days and when it doesn’t, it’s still in the high 90’s. And it has been very dry. It feels better to us for the humidity to be low, but plants need some water. So, even though I think I shouldn’t, I feel like I should go out there and water.
The thing is that many California native plants need a couple years of water before you can let them be during the summer. In a couple years my backyard should need little to no water at all. Only when I plant something new will I need to go out and actually water. The website for the Las Pilitas Nursery is another treasure trove of information for California native plants and the author, Bert Wilson (now deceased), recommends spraying native plants to rinse off dust, but otherwise, not to water them. That’s what I try to do. But, some of my plants are still very young while others are close to being “established” in the yard, meaning their roots are developed and extensive enough to support the plant through heat and drought with minimal assistance.
The worst part, for me, is that I lose some plants anyway. My sticky monkey flowers always seem to brown and die in the heat. I’ve lost four of them this summer and several last summer. And the sages can sometimes wilt and die back in the heat. The worst hit has been my vegetables. My pumpkin plant stopped producing fruit after one pumpkin, as did my butternut squash plant. The zucchini vines withered and the tomato plants are struggling.
And, another issue related to this is that the wet soil attracts gophers. So, I had started watering more broadly over larger areas to try and confuse the gophers as to where the roots are, since I’ve had a lot of plants killed by the awful rodents.
Weather West, one of my favorite blogs says we should expect continuing hot weather of much the same intensity but with more humidity over the next week to ten days.
Has the summer brought any challenges to your garden? Lost any plants? Has it been unusually hot where you are, too? Feel free to add a comment!
My White Sage (salvia apiana)
White sage has become a favorite plant of mine. It is elegant and grows well in my yard. I have wanted to focus some posts on specific plants for a while. So, this post will be looking at white sage and my experience with them.
I have chosen a number of sage plants to go in my native plant garden mostly due to reports of their fragrance and easiness to grow. Both seem true at this point. As the picture above shows, I have a couple of white sage plants in my yard. Bees and hummingbirds love them. And, when they are doing well, they produce tall flower “wands” that shoot up over five feet tall. This one pictured is at least six feet tall in the highest stalks.
They have dealt with extreme heat. We regularly get temperatures over 100 degrees in August. And, last year was extremely dry. As it was the first year, I supplemented its water supply heavily. For the first year, I watered daily during the summer. I dropped the frequency down during the fall and stopped watering once the rainy season began this last October, unless it was still dry out. This summer I am watering about once per week, or so.
I have two other white sages that were pretty small for a while there. In fact, they still aren’t as big as the one above. But, I started watering them more and they got much bigger. So, early on, I would say that white sage enjoys a good amount of water. But, I have read that watering them less after the first year or two is a good idea. That seems true. But, I haven’t had the trouble with them being stressed from too much water like I have with my ceonothus plants.
When white sage is in bloom it is a beautiful, very stately plant. The stalks of white flowers seem somehow heroic to me, rising skyward in defiance of gravity and serving as a beacon to birds and bees. I’m of the understanding that the stalks can be harvested and dried to make smudging sticks for Native American rituals, but I have not done so myself. I may give it a shot this year.
My soil is mostly loam but very rocky and layered. The first six inches, or so, is loamy sand. Below that is a lot of rock, majority granite, in potato-sized chunks, but there are some much larger rocks, too. I’ve pulled out quite a few that are over a foot wide and weigh what feels like over thirty pounds or more. That layer goes on for about a foot or two. Sometimes there are pockets of clay or sand. After the rock layer, there usually is a layer that is sandy and rocky. I’ve never dug down further than about 3 feet, so I’m unable to attest to more from my own experience.
I planted these sages from pots I bought at Grow Native Nursery in Claremont, CA (at the Rancho Santa Ana Botanical Gardens). They were all quite small, most in gallon or smaller pots. I dug holes that about twice as wide and deep as the pots themselves. I filled the holes with water twice before installing the plants. Then, I made sure the base of the plant was about one inch or so higher than the surrounding dirt. I buried the roots and packed the dirt slightly, just to get rid of air pockets, but not so much to avoid inhibiting root growth. I watered almost daily in the beginning. No fertilizer. Mulch is good, though.
Overall, I recommend this plant. I currently have eight of them. I just planted four this fall. Two of those already produced flower stalks! They are already significantly larger than when I planted them. So, this plant grows pretty fast. And, it can easily spread to 5 or 6 feet wide, so keep that in mind. The leaves are a light-green, near to silver. They offer a nice contrast to darker foliage. One of my white sages died, I think from a gopher. Another got a pretty bad bug infestation that seemed to kill a lot of leaves. The plant itself is still alive and producing new leaves and stalks so I’m keeping an eye on it. Not much I can do for it, though. I’m trying not to use anything stronger than Neem oil on my plants. I am going to try raising some from seeds if I can figure out how to harvest them.
I’d be interested to hear from readers if they have questions about the white sages or experience with them. Thanks for reading!
