I have grown this sedge for three years now in shade in my northern Virginia garden. Each October I remove it from its pot stand and plant it in the ground for the winter. The first winter it survived Snowmageddon of '09-10. Last winter it survived our more normal changes between melted snow and cold temperatures down to 15 degrees. During the summer in its pot it produces seed heads, but I have yet to sprout any of them.
Before I planted it but after I read the article in FG, a botanist at the Berkeley Botanic Garden told me during a visit there that recent DNA research had shown that this sedge is actually not a CA native, despite its name. That gave me courage to order it from a West Coast nursery. I just wish the word would reach the Mid-Atlantic nurseries that this is a grass to order for their customers.
