How To Plan For The California Native Plant Society, San Diego Chapter, Fall Native Plant Sale
“Using appropriate techniques and principles … you will be able to create native gardens that are beautiful year-round with low mortality and maintenance. … [When it comes to California native plants] there is literally a plant for every situation imaginable,” (From Greg Rubin and Lucy Warren’s book, California Native Landscape, the Homeowner’s Design Guide to restoring Its beauty and Balance., pages 9-11.)
The CNPS native plant sale may be a month off, and now is a great time to start planning what and where to place your new plants. Consider your garden conditions (sun, shade, soil, etc.) and what will fit in where you have open areas. You may even decide to replace a whole section of your garden. Here are some essential things to consider for your plan.

In the wild, plants grow in communities and replicating this pattern in your landscaping helps achieve a natural balance. Plant communities that do well with inorganic mulch include coastal strand, grassland, riparian, desert, and pinyon-juniper woodland. Coastal sage scrub, Chaparral, oak woodland and redwood forests like organic mulch with rocks by each plant. Communities that need exclusively organic mulch are Mixed Evergreen forests and Pine Forest. Many species are found in more than one plant community. Oaks for example are found in Oak woodlands, Chaparral, Coastal Sage Scrub, riparian communities and evergreen forests. Consider what community is common to your property to pick out the species that will be most successful.

Within plant communities, species may be grouped by their specific requirements. What kind of soil do you have? It may not be the same in all parts of your garden. Is it sandy, claylike, or somewhere in between? How is the drainage: fast, medium, slow, or not draining at all? What is your soil’s pH? The soil type required for many native plants varies and this will affect how you water the plants, especially when they are newly planted. If you are adding these native plants to an area with existing plants, make sure that they can tolerate the same watering schedule. Some natives cannot take excess water and others are happy with whatever amount of water you give them. Are you planting a perennial that needs full sun and may be shaded as nearby plants mature? Or is it a plant that does well in any light?
With careful planning and a bit of professional help, Bird Park, located at on 28th St and Upas, SD, seen above, is a great example of what can be done with native plants to create a natural area.

Is your garden a particular style, like contemporary, Japanese, English or wild? Maybe you are starting from scratch and have a particular style in mind. For suggestions of which natives work best for different styles please see Greg Rubin and Lucy Warren’s first book. In their book, you will find suggestions for Formal Gardens, using geometry and balance, and Contemporary Gardens with hard edged linear lines bordered by hardscaping.
For dryer areas in your landscaping, succulents will do
nicely like this Chalk Dudleya, Dudleya pulverulenta, which is about to put on a flower show. Photo by Susan Lewitt.
Mediterranean style gardens give you warmth, softness and color with vertical accents. The southwestern style is sparser using desert natives with DG and pebbles as mulch. Finally, Asian style gardens purposely use evergreen natives that highlight leaf color, texture and sculpture.
Avoid the common mistake of placing native plants too close together, leaving space for their mature growth. Many native plants have a growth pattern known as “sleep, creep, then leap” and allowing ample space accounts for this growth spurt.
You don’t have to monkey around with exotics for color in your landscape. How about some native Monkey Flowers, Diplacus spp., which come in red, yellow and orange?

A closing thought, also from Greg and Lucy’s first book, page 11:
“Few Californians know how California used to look, it was definitely a lot greener. John Muir spoke of being able to walk from the city of Los Angeles to the Northwest San Fernando Valley without ever leaving the shade of an oak tree.”
