Ann Clary

Ann Clary


Ann Clary met her GardenZeus.com co-founder Darren Butler at one of his intermediate gardening classes and she became inspired to grow new and different plants in a sustainable, bio intensive manner.  After finding herself constantly creating monthly to-do lists for California gardening from four or five different resources, she thought there had to be a better way.  This became the original impetus for Ann and Darren’s partnership, the process that evolved into GardenZeus.com.

Ann is a professional lawyer and administrator, and an avid amateur gardener. She lives in Pasadena, California and she enjoys cooking for her husband and two grown children. She especially likes to cook what she grows in her vegetable garden. Ann is a big fan of Alice Waters, Julia Child, Thomas Keller and Nora Ephron. She says, “I know Nora was not really a professional cook, but she liked to cook and had lots of funny things to say.” Ann is also a competitive tennis player and an avid Stanford Cardinal football fan.

Yvonne grew up on a 3/4-acre hillside lot in Pasadena in Southern California, with year-round fruits and vegetables and flowers homegrown with lots of manure and compost and “making do” before it was called recycling or repurposing.

Since 1984, she has contributed weekly gardening columns, features, and photographs to California and national newspapers, magazines, journals, and newsletters.
