The Carter Gardens in Eureka are an excellent local gardening resource.
Carter House Inn guests are invited to help in the harvest, gathering produce for the meals. "In addition to supplying the inn's restaurant with produce of the highest quality and freshness, the Carter
Gardens have become a center for horticultural education, home to organic gardening seminars, lecture series, and interpretive tours given by the inn's Master Gardener." (source)
The Carter Gardens' Plant Lists are a wonderful resource for planning your own gardens.
