Recall the heat damaged new garden install at the neighbor's house? It shows no signs of a hard start in life. What you see below are Encelia for the most part, planted because the neighbor requested "sunflowers". What he really wanted is in the background in this photo. Sharing is caring they say.
There's been a lot of information posted over at Mother Nature's Backyard blog since I last visited. Mother Nature's Backyard is particularly relevant to me,
since they write about California native plant gardening in back yard location
mere miles from my house.
To my chagrin, it was dropped from my list of blogs to visit regularly. However, in a way it's fortunate that I've gone so long without a check in since they are now on part 11 of a garden design series that I think is quite insightful, giving me plenty of reading and thinking material to digest in one go. I might have found it frustrating to wait for the installments if I were following along, so perhaps it's a lucky thing that I was able to catch the design series late in the game. I'm not quite through with it, but it seems thorough so far - more like approachable class material than a casual blog post. No specific author is listed, but I suspect that Dr. Connie Vadheim (CSU Dominguez Hills) is the main author of the design series, so it should be no surprise that the series is as thorough as it is.
So far as I can tell, they don't have a table of contents to the design series, so here is one:
This is the first year of bloom for Eriogonum grande var. rubescens (Red Buckwheat) in my garden. This photo was taken June 4 and shows the one plant that has spent a year in the garden. However, others that I installed in fall are also blooming to a lesser degree.
Earlier this year I decided to install some Iris 'Dark Clouds'adjacent to my 1 year old Iris 'Canyon Snow'. My experience is that Iris are hard to initially transplant and establish, but once they have taken hold in the garden they are robust. Additionally, Iris can look ratty after they bloom, but it's been my experience that if they have any strong and healthy growth, that they will survive and come back the following year.
One of my more established 'Canyon Snow' had about a 50% die back, but I wasn't too upset, since the remaining growth was strong.
However, two of three newly installed Iris 'Dark Clouds' had a significant amount of die back with little corresponding strong growth. I'll continue to baby them, but they may be goners.
Mesembryanthemum crystallinum (common iceplant, crystalline ice plant) found adjacent to the road in at Portuguese Bend. I had thought since I first observed it that this was a native, due to the tenacious way that it clung to seaside crevices and novel appearance of dew drops on its leaves. I was wrong. It's actually an invasive plant. Wikipedia has useful information.
The plant usually uses C3 carbon fixation, but when it becomes water- or salt-stressed, it is able to switch to Crassulacean acid metabolism. Like many salt-tolerant plants, M. crystallinum accumulates salt throughout its life, in a gradient from the roots to the shoots, with the highest concentration stored in epidermal bladder cells. The salt is released by leaching once the plant dies. This results in a detrimental osmotic environment preventing the growth of other, non-salt-tolerant species while allowing M. crystallinum seeds to germinate.
Atriplex lentiformis Breweri (also Salt Bush, Quail Bush, and formerly Atriplex Breweri) grows abundantly on the Palos Verdes peninsula. Out on a hike the other day I noticed what appeared to be galls on it:
I asked in my previous blog whether I ought to prune my new Garrya elliptica 'Evie'.
I did and here's what it looks like.
Time will tell whether this was good choice or not. I sort of think that it was, based on the principle that pruning early in life sets longer term growth patterns, and given that this is a potted plant, I need to keep it a somewhat compact.
I Googled some interesting commentary from the California Native Plant Society about this genus. G. elliptica is not actually native to LA County; it is naturally found in Ventura county north. Perhaps a better choice for my leeward side of Palos Verdes in the generally more arid Los Angeles county would have been as indicated in this except from the CNPS web page on Garrya.
In Southern California, G. elliptica likes extra watering, but it also needs well-drained soil. Plants grown in insufficient drainage can be prone to water molds. The species in general is also susceptible to Botryosphaeria, a fungal disease that can result in branch dieback. Pruning in summer months and with proper hygienic practices will help deter the spread of this pathogen.
If you are not on the coast, seek out the species of silk tassel bush like G. fremontii or G. flavescens that grow in inland areas. G. flavescens
is native to chaparral areas in Southern California, and lights up
like a Christmas tree when in bloom. These species can be much more
difficult to find than the more readily available G. elliptica, but your search may be rewarded with an unusual specimen of beautiful native shrub.
I had the misfortune of installing it right before a series of unprecedented hot days and the plants suffered for it. I thought that I would be replacing many plants, but it turned out that at least the Encelia (Brittlebush, goldenhills, incienso) have made a recovery. I think it helped that I clipped the branches back about 1/3rd, though not soon enough to prevent loss of nearly all their leaves.
The recovery was first evident to me on 5/24 with the releafing shown below:
By 6/1 recovery was in full swing:
6/8 even more growth:
I wasn't so fortunate with the strawberries (Fragaria) and was forced to replace all but one. Still, I felt fortunate and I'm surprised by the strong recovery of the Encelia.
This one from Lowes caught my eye because it is simple and has a number of design elements that I might like to consider. It also has a bill of materials and costs for each part of the construction. Overall, this is just the sort of useful garden construction advice that I like to see online. Bravo to Lowes.
However, one of the design features of the arbor is a "rain catcher" which is a section of 6" PVC pipe stood on end and fed by a downspout. Go to the article linked above to see the construction details or just take my word for it. The BOM is reproduced below showing a total price of $125!!
"A new company, Turf Terminators, will replace high water usage yards
with low water, drought tolerant yards at no cost to homeowners, " according to the LA Daily News.
The plan is to use rebates from the water company to fund the conversion. OK so far, and a reasonable way forward for many homeowners. However, looking through the photos the design and plant selection don't seem that inspired. Plant materials seem to be exotics (I noted oleander, kangaroo paw, a flax and perhaps one California native, Giant Wild Rye) all crowded too close together in a field of decomposed granite in this photo. A Facebook photo shows shrubs with ground cover mulch around their bases. Since their web site doesn't give me an easy way to see the details of their process without "getting started", I don't know if their landscapes always look like that. They do say, "Turf Terminators' landscapers will replace your lawn with California
Friendly plants and ground cover over the course of 1-2 days" which begs the question of exactly how well the lawn is removed.
Given the attention that many homeowners give to their gardens, this company might have a success on their hands.
Turf Terminators has a Facebook page at https://www.facebook.com/turfterminators and a web site at http://www.turfterminators.com/.
I'm pleased with how this prostrate Chamise (Adenostoma fasiculatum can't remember the exact name) and “Santa Barbara Liveforever” (Dudleya traskiae) have grown in these clay pipes that I've placed on end. I'll have to get some more. I liberated the larger from underneath my parents' house where it was forgotten for a long time. The smaller also came from their house where it was part of some yard drainage.
