A Garden that’s Alive! Dan Songster
“Once a garden comes alive ecologically, it displays a humor and richness of meaning that have been missed by narrow views of horticulture. Significance expands. Meanings multiply. Each plant or planting becomes much more than what nurseries believe they sell, or gardeners suppose they grow, or visitors would notice.” Noah’s Garden, by Sarah Stein
We are in love with the wilderness. Such vibrant spaces speak to us saying, “Wander in me, discover my secrets, drink me in, inhale me, I am real.” Our state’s natural areas are rubenesque in their fullness and diversity, richly endowed with color, scent and texture. And they are alive! Birds are everywhere eating berries and seeds, hummingbirds sipping nectar, native bees, flies, dragonflies, and butterflies in various stages of development, many animals busy with their daily (or nocturnal) activities, along with the not so obvious fungal and bacterial alliances operating silently in the soil itself. How can we not be in love with such active landscapes? Whether it is the shady oak understory, the gray-green tapestry of our coastal sage scrub, or the elfin forest of chaparral, they are all magnificent. A small plateau of native grasses saturated with the purple of Brodiaeas and bordered with the shaded apricot of Mimulus. A grouping of boulders long ago rolled to where they now lie half-buried, with Dudleya and Coffee fern beneath and between, a cloak of dark green Coffeeberry above. A simple bank of rusty Buckwheat blossoms against an amber sandstone background. How many miniature gardens do we find on a single hike in the nearby hills? Hundreds of glorious scenes worth stopping at to take notes, sketch, photograph, or simply gaze. And each of them provides some benefit, often essential, to the animals that live there.
So it is only natural that slowly (even here in lawn-carpeted western landscapes) we would wish to incorporate these native plants into our gardens and invite such critters into our landscapes. Of course there will be differences between our gardens and the real thing. In our nearby wildlands the plants grow because a seed washed up behind a boulder and stopped long enough to germinate. Dead plants serve as a perch before slowly decomposing into mulch. A few dry years in a row? No additional water is added. Gardens, however, are by definition a controlled environment. Even those gardens designed to imitate some natural association of plants we have spied in the wild are still designed and so require some maintenance. Rather than growing as chance dictates since space is often very limited, individual plants are carefully placed, overly competitive plants may be thinned or removed, dead plants, rather than slowly becoming mulch, are simply removed, and water can be provided when rain fails. Still the overall concept follows a natural pattern and its maintenance is relatively low, and most importantly, the gardener is more than rewarded by the forms of life that adopt the garden as their home.
So how do we go about designing and installing such a garden? Research for such a landscape is now easy as numerous books and magazines present practical guidance on this now (deservedly) popular trend. Native gardens such as Rancho Santa Ana Botanic Garden and smaller ones such as the Golden West College Native Garden provide blueprints for what is successful (or not) and can also be a source of practical installation advice. Field trips into our local hills provide glimpses of many of the plants that can be used and the interesting combinations in which nature arranges them. By selecting plants that remind you of a hike in the local chaparral, coastal sage scrub, oak woodlands, or even along our coastal bluffs, you bring a bit of that adventure into the environment surrounding your home. It is a structure that invites interaction both by you and the animals it attracts, as opposed to the conventional landscape of lawn, hedge, and rose with its routine upkeep and its singular purpose of being viewed.
And so these plants are familiar but wild, tamed but not entirely so. The garden is designed but is allowed and expected to change. Its structure is a framework for plants that invite the nearby birds, butterflies, and insects to join into a landscape that is full of life, a garden that pulses with the cycles of seasonal change. Once we arrange and install the garden’s “ingredients” we then need only wait to receive our visitors. That is when the garden becomes truly alive!
(Note: Almost three-quarters of the plants sold at our upcoming sale have inherent habitat value. Don’t miss it!)
September 20 (Thursday)—THE CALIFORNIA LANDSCAPE: IT’S NOT ABOUT THE PLANTS
Speaker: Mike Evans
All gardens feature plants on exhibition. By definition, the various and familiar theme gardens, such as the herb garden or the rose garden focus on the plants of their titles. In the “California native plant garden,” natives are certainly on display, but it’s not about the plants. It’s about what the plants do for people interacting in or with the garden. California’s unique climate, history, and culture provide us with a canvas for a classic painting. In this talk, we will consider various aspects of the “California Garden.” Whether our purpose is to imitate nature by attracting wildlife, provide an authentic sense of place, focus on the natural or historical beauty of an area, plant in an urban setting, or conserve resources, the process of creating a “California Garden” is ultimately life-giving for the gardener and the user.
Mike Evans is the founder and co-owner of Tree-of-Life Nursery, the largest native plant nursery in the state. He has more than 25 years of experience in growing natives in Southern California. A native of Orange County, he is active in many horticultural and botanical societies.

From the 405 exit east on Sand Canyon, turn right on Waterworks and left into the parking lot. Enter the building from the rear.
2001 GRANTS—an update
The field season has been very successful and interesting. I am investigating the pollination biology of Artichoke thistle (Cynara cardunculus). My study site is Starr Ranch Audubon Sanctuary. Here, Artichoke thistle flowers from early June through early August. From June 17th through July 5th in two grassland sites, I made 15-minute observations at study plots with dense and sparse thistle floral displays for a total of 72 hours. This data will enable me to determine the extent to which thistle pollination and seed set is flower density dependent. To ascertain its ability to self-pollinate, I covered thistle flower heads in each plot with bridal tulle to exclude pollinators. This past week, all mature inflorescenses were harvested for seed set evaluation. This fall, I will analyze the data collected this summer and plan for next year. I learned a great deal about the major pollinators of Artichoke thistle, which include several species of bees and hummingbirds. I observed what native plants co-flower with thistle and share a pollinator. These are Keckiella cordiflora, Castilleja affinis, Chlorogalum parviflorum, Hemizonia sp., Saliva apiana, Salvia mellifera, Eriognum fasciculatum, Asclepias eriocarpa, Asclepias californica, and Asclepias fascicularis. Heterospecific visits by pollinators to thistle and several native species were observed. I look forward to an experiment examining the effect Artichoke thistle is having on the pollination and reproductive success of co-flowering native species next year. In addition, I hope to quantify the reproductive success of hummingbirds nesting in Artichoke thistle. I found high densities of Costa’s and Black-chinned hummingbirds nesting at my study plots with most nests failing. Artichoke thistle may be a resource and habitat sink for migrating populations of these birds. Thank you so much for the support.
