Carol Anne Ebert & Dawn Griep

Carol Anne, an Island County Master Gardener, has a passion for gardening, landscape and floral design. Much of her botany, horticultural and design knowledge was gained during her undergraduate years at Cornell University. Her gardens and floral designs have been featured in numerous garden tours and fund-raising events. As a basket weaver and stone sculptor, Carol Anne found making kokedama a new and relaxing way to use many of her design and construction skills.

Dawn is an avid gardener, thoughtful landscape planner and sought-after floral designer. As soon as she could handle a hose, spending time in her family’s extensive flower and vegetable gardens became her true passion. During her teenage years she worked for florists after school and on weekends. This experience combined with her creative floral design skills and her entrepreneurial mindset placed her in a position for employment as a floral shop manager. Her stature in this profession was recognized and she was asked to join the Washington state’s teleflora Board of Directors. Her talents were used to develop design programming to help local floral shops learn and grow. Today, Dawn has focused primarily on the outdoors and has her own consulting practice assisting clients in planning and maintaining their greenspaces. When her schedule permits, she also provides floral design planning and execution for special events. Dawn is particularly drawn to container gardening and kokedama has become another favorite.
