Artist Bibby Gignilliat's Mill Valley Dahlia Obsession
Mixed-media artist Bibby Gignilliat has transformed her Mill Valley, California garden into a vibrant, unstructured display featuring over 125 dahlias

Mixed-media artist and teacher Bibby Gignilliat's garden in Mill Valley, California, is now defined by an explosion of dramatic dahlias. According to a profile on Gardenista, she purchased the property in 2013 and began reworking the landscape almost immediately.
Bibby hired a garden designer for the initial overhaul, removing elements like two old sheds and an unappealing front hedge that did not reflect her style. The garden has evolved in stages since then, deliberately without a formal plan. "Not surprisingly, is the part she loves most," the source notes.
Creating an Outdoor Living Room
She extended the deck and created three separate gathering areas. This layout was designed to facilitate a "progressive dinner party" where guests could move through the garden as the evening went on.
Professionally trained as a chef, Bibby ran a cooking and events business for two decades before becoming a full-time artist. Food, creativity, and entertaining have always been central to her life, directly influencing her garden's function.
The Rise of the Dahlia
The garden's original planting included just one hot pink dahlia. Bibby was instantly drawn to the flower's colors and forms.
The source provides the following breakdown of her planting:
| Location | Number of Dahlia Bulbs |
|---|---|
| Front garden | 100 |
| Backyard | 25 |
She concentrates the plants in sunny areas and around the fire pit. Bibby routinely brings dahlias indoors for arrangements, gives them as hostess gifts, and takes bunches to her artist's studio in Sausalito for Open Studios events.
Artistic Parallels in the Garden
Bibby's artistic practice is layered and textural, involving building up surfaces and then excavating back into them. She says this intuitive process, which embraces bold colors and unexpected moments, mirrors her approach to gardening. There is a freedom and flow to my work that I think is also very present in my garden, she shares.
She explicitly did not want a perfectly manicured space. I am much more drawn to the feeling of an English garden: organic, abundant, a little wild and allowed to do its own thing, Bibby adds.
Lessons in Letting Go
Years of gardening have taught Bibby about relinquishing control. She compares it directly to her art-making process. A painting might begin with a plan, but she must eventually listen to what the painting itself suggests. She finds that some of her favorite moments in both painting and gardening arise from unplanned developments.
