Heart Leaf Geranium
At last, a drought tolerant shade plant with orchid shaped blossoms that bloom from January to
mid summer! This plant, discovered in Cape Town, South Africa, was introduced to the Royal
Botanic Gardens by Francis Masson in 1774. Today, it is considered rare and difficult to find. The
2” flowers are pink with magenta markings on the petals. The heart leaf geranium has velvety,
heart-shaped leaves with the scent of apple. Additionally, it is seaside and salt tolerant. The Kids’
Adventure Garden has fine examples of this easy to grow rarity.
Butterfly Bush
During the Victorian-era, explorers brought all kinds of exotic plants back to England. From China
came seeds of Buddleia davidii, the hardy species that is most familiar to gardeners today. Named
after French Jesuit missionary, Pere Armand David, the seeds reached London's Kew Gardens in
1896. Horticulturists are still combing the Himalayan foothills for as-yet undiscovered Buddleia
varieties.
The butterfly bush is a magnet for all the butterflies who pass through the garden seeking nectar.
In fact, many butterfly gardeners plan their garden around Buddleia davidii. There are many
different types, so the plant characteristics and color can vary. Butterfly bushes are drought
tolerant and easy to grow!

What’s in a Name?
by Diane Conejo
Ceanothus, or California Wild Lilac, is an evergreen, native plant that has gotten a bad
reputation for a few reasons: None very serious, some completely false. Please read on with
an open mind.
First of all, its new growth is considered ‘tasty’ by deer. Not always, but lower-growing
species should be protected when young and tender. “It takes a while to ‘take hold’ and
branch out.” Ok, gardening is about patience. Once its root system matures, it will likely
surprise you, so don’t pull it out yet! A little judicious pruning once it’s well-established (in late
spring) will help the plant to fill out.
It has been said that Ceanothus is a short-lived plant. This is a rumor that was likely
spread by gardeners who lost the shrub by insisting on drip irrigation, summer watering and
soil amendments, all of which are totally unnecessary in the case of this very undemanding
shrub! Summer water should be administered infrequently the first year while the plant is
developing. Wild Lilac can usually sustain a 20-30 span in a native garden with very minimal
water.
Leaves turning yellow...if you are overwatering or there is a lot of rain (not likely); you are
using amended soil or fertilizer, you will see yellow leaves. If you can answer “none of the
above” and it is springtime, remember that Ceanothus drops old leaves while it is pushing new
growth. This is nothing to worry about.
Pests... Ceanothus actually has a very low pest incidence. The Hyalophora euryalus or,
Ceanothus silkmoth is a large moth species (3-5” wingspan) whose female glues its eggs
singly or in clumps on the leaves of the host plant. The eggs hatch in 9-14 days and
caterpillars eat the leaves. The cocoon is spun on the outer part of the host plant and attached
to a twig by one half of its length. It is an interesting life cycle and most likely won’t destroy
your entire plant. Besides, this moth is a beauty!
There are many different varieties of Ceanothus, from groundcovers to various sizes of
shrubs. The thyrse inflorescence appears in late winter to early spring and ranges in color
from frosty white to deep cobalt blue. The foliage comes in many hues of green but there are
also variegated hybrids (and these actually have yellow edges on the foliage, see photo
above). It is a sturdy plant if we take the time to understand what’s important to keep it
healthy. To review various species and hybrids, check out:

Want to Help us Grow? Do you love Conejo Valley Botanic Garden and would like to help, but just don't have
the time to volunteer? Even though much of the work you see going on in the garden
is done by volunteers, we still have expenses for planting, heavy pruning and new
improvements. These projects are funded through grants and donations from the
community. If you would like to help us grow, tax deductible donations are always
welcome and may be made out and sent to Conejo Valley Botanic Garden, 400 W.
Gainsborough, Thousand Oaks, CA 91360. Thanks for all your support! Conejo Valley Botanic Garden Needs You! The Garden is managed and maintained by community volunteers. Without your help,
the garden cannot thrive. None of the volunteer positions at CVBG has a minimum
number of volunteer hours attached. If you can help for a few hours a month, great! For more information on any of our volunteer opportunities, please go to our web site
at www.conejogarden.org and click “Volunteers.”
WE CURRENTLY NEED VOLUNTEERS FOR THE FOLLOWING PROJECTS:
Adopt A Garden: We have an ongoing need for volunteers to join the teams working in
our theme gardens. Days and hours are flexible so give us a call.
Garden Nursery: There is no better way to learn about California native and water
wise plants than to join the teams working in the propagation and sales nurseries.
The Kids Adventure Garden: KAG is open from 11:00 to 3:00 each Sunday. Docents
welcome families to the garden, answer questions and ensure everyone is safe
and has fun. You will train with an experienced Docent. You can sign up for one
shift a month or as many as you want.
