"Canyon Sparkle" Manzanita (Arctostaphylos insularis)

Thanks Las Pilitas Native Plant Nursery
Arctostaphylos insularis 'canyon sparkles'
I love this Manzanita "Canyon Sparkles" I picked up at Las Pilitas Nursery north of Escondido CA almost 7+ years ago. The very first year I planted it in the Fall of 2005, I watered the shrub once a week for two months, then twice a month for two months, then once a month until the following rainy season. It should be also noted however that I also heavily inoculated it with an excellent mix from Mycorrhizal Applications Inc of Grant Pass Oregon. After that first year - 'NOTHING' was done. Other than a nice layer of fresh mulch applied once a year which helps retain any moisture and keep plant roots cool, this plant got no artificial watering after that first year. Well, other than El Cajon California's seasonal rainfall which has been low like the rest of Southern California. One big advantage in training this shrub has been the extremely deep layer of sandy loam soil from a once ancient existing Bajada or Alluvial Fan which is nothing more than a Canyon mouth geological feature. Deep roots mostly likely now penetrate the deep subsoil moisture. 

I also noticed this year for the first time why this s called "Canyon Sparkles". The newer foliage or leaves are glossy dark green and shiny in the sunlight. This has been the first one I've ever planted, so it was a bit of an experiment. But what a success. I also noticed that when it started to bud out with newer leaf stems and flower bud clusters, there are now countless numbers of winged insects attracted to some scent this shrub is giving off prior to full mature bud development and flower opening. This was the same phenomena I experienced up in Anza with my California Coffeeberry bushes in Springtime. Thus far there have been all manner of differing flies species and many many Ladybugs. Honey Bees and Wasps are also visiting. Weeds have also never been a problem around these shrubs.

This is the view angle from the street and neighbour's driveway. In fact the neighbour actually dislikes this plant and has her gardener chop some of the branches on my mum's side of the iron fence. This is the same folk who got my mum to remove the Laurel Sumac in the backyard. Whatever! 

Arctostaphylos insularis 'Canyon Sparkles' 
This view is direct from the street and curb view of my mum's driveway. At the very lower right of the photo is some very long and lush growth coming from the ground. I believe some branch has now rooted on the ground and re-sprouted. This is actually very common with many Manzanita   and they may be cut and transplanted elsewhere as a new plant, but I thought this would be damaging to the little tree as the growth is young and rather succulent. Too delicate to chance a move, so maybe next winter if I'm around here again.


This is simply a close up shot of the vigorous foliage growth coming from the ground under the main plant. I'd love to put one on the opposite side of the driveway across from this one, but once again I feel it's a timing issue and feel it's much too late and temps are very hot now. Works for me, but the plant is another story. The water rates are outrageous here and the sewer fees are also ridiculous because they are based on how much water you use, irrespective of if you are watering the landscape as opposed to it all going down the drain. Drive around most El Cajon and Santee Ca neighbourhoods and you'll see countless yards which look like a wreck. This mostly has to do with insane water bills. In the old days everything was lawns with trees in them. Things have changed radically. People is these southern California areas need to plant and work with more So-Cal natives. Of course that takes education and understanding of just how the natives actually work and what their requirements are. Not all are rangy looking as evidenced from above. But you truly do need to understand all the differing requirements and needs of each and every one of them you will choose. Doing so will allow you to develop and design any  specific plant community theme if you choose those with similar needs.  

One of the other things for which I appreciated about this particular plant is that it is considered a central coastal Manzanita and you'd think it would only do well along the coastal areas. Not so as the seven plus years of heat and drought of San Diego County's interior valleys have proved otherwise. Being that it is my first experience with this plant, I have no idea how well it would do at higher colder elevations of Southern California mountain ranges.

Pozo Blue Sage
This hybrid Cleveland Sage, 'Pozo Blue' (hybrid between (Salvia clevelandii) & (Salvia leucophylla),  is planted next to the Manzanita. Both have similar requirements and like the Manzanita, this plant does not receive summer watering. Only main care for Cleveland Sage is to cut it back in Winter for full lush growth following year after rainy season. As always, inoculate with Mycorrhizal mix. This not only keeps it further drought tolerant and allows for better nutritional uptake, but it will also make those important interconnections with it's neighbour plantings allowing both to share the chemicals the others manufacture.

For the moment this plant has been giving off the most wonderful aroma reminiscent of hiking the backcountry of San Diego County. Believe it or  not, I actually use the leaves of this plant for  cooking Pinto Beans. I also use it as an air  freshener for the Automobile. This plant was also  purchased at Las Pilitas Nursery (Escondido) Below here in the final photo is an image of "Canyon Sparkles" Manzanita showing other uses for which you may find it attractive to utilize in. This picture is from Pete Veilleux on January 10, 2010. Clearly there are some creative alternatives in using native plants. Even in these pots, don't forget the Mycorrhizal mix and careful on those chemical fertilizers. I love the small cobblestone mulch utilized here.

Arctostaphylos insularis - Island Manzanita 'Canyon Sparkles'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Update September 2015
In 2014 I planted one other Island Manzanita further down the side of the wall from the larger Manzanita which was the subject of the article here. Below is the photo from 2014 of the one gallon Arctostaphylos insularis I again purchased from Las Pilitas Native Plant Nursery location just north of Escondido. At time of planting, the temperatures were 100+ degrees, which according to most conventional Landscaper & Gardening experts is a big green thumb no no. I've debunked all that several times over and time of day and mycorrhizal application of inoculum is the key. 
See my post from 2014: 
Is it safe to plant & water California Natives Plants in Summer ?


Image: Mine (July 2014)

The key to the success was planting all the new plants just after sunset which allows the plant a measure of some recovery. Also basically leaving the one gallon plant's root zone undisturbed by loosening or breaking it up a bit. I have a practice of never purchasing and planting no bigger container plants greater than one gallon. In some rare cases where specific hard to get plants are not to be found in most Nurseries, I will purchase and plant from five gallon plants and on extreme rare occasions like Blue Mexican Fan Palm (Brahea armata) which I recently purchased on this trip in 2015, I had no choice but fifteen gallon specimens. More on them late in another posts as they are a sensitive plant to establish and hence I used a more robust MycoApply from them called "Soluble Maxx" with far more species of robust mycorrhizas. But getting back to the Island Manzanita which is NOT recommended for hot interior valleys of Southern California because they are a Channel Islands chaparral native plant, I also inoculated them with a mycorrhizal mix from Mycorrhizal Applications Inc from Grant Pass, Oregon called MycoApply. The "All Purpose Soluble" is what I purchased from one of their distributor 'Horizon Distributor's Inc' (Commercial Landscape Irrigation Equipment Supplier) on Engineer Road in San Diego. Below is the almost exactly a year later result.

There you have it. A very health happy Island Manzanita and their are some other reasons for this. First credit goes to the MycoApply because Manzanita like some other similar plants like those of Arbutus have no real fine root hairs like those of other plants, hence they require nature's performance enhancer Mycorrhizal fungi. Second, this location is a very fortunate one since it is next to a sloping concrete driveway which channels rainwater runoff towards this side yard, in effect concentrating the rainfall totally and artificially creating a higher than normal rainfall average in a sense. However, Southern California has been under extreme drought the past 4+ years and rainfall amounts and the far apart spaced out storms have dropped very little as compared to what is normal. Still the sloping drive has been a plus. Little if any supplemental water has been provide with the exception of watering done by my brother there for a few months after we planted and left in July. Mostly once a week the first month (July) and thereafter once a month in August and September & October until winter rains came. Nothing after that with the exception of a wonderful long days tropical rainstorm August 14/14 2015 while we visited. You can see the results of newer light green growth triggered by the Thunderstorm.

    1. Great to hear. So where do you shop for Natives ? Living Desert Museum ? I know their prices are expensive, but I can't think of another place in your area.

  2. Totally cool Timeless! Great blog post. We do ship mail order trav4adventures... if you want local stuff we try to grow things form all over Calif so you can get things native to your area. The Living desert museum has great stuff to though. I send people there a lot if we don't have something.

    1. Thanks Penny

      BTW, You guys have permission to use the photos of what were your plants and utilize these in your education and advertising of your Nursery. I haven't even posted the pics of the 7+ year old California Sycamores, Sugar Bush and California Spice Bush which are all growing luxuriantly in the backyard and don't get any summer water either. The 7+ year old Sycamores are close to 40' or more tall. The Spice Bush is massive. It's all about hydraulic lift and redistribution and the interconnections of the Mycorrhizal grid network making everything a success. I'll post on those later.

      Thanks again

Thanks for visiting and for your comments!

I will try to respond to each comment within a few days, though sometimes I take longer if I'm too busy which appears to be increasing.
