I have a couple of questions. Does anybody know what the hardiness range for Neomarica gracilis is? I need to decide whether to plant it in the ground or keep it in a pot in the greenhouse. Also -- this summer I have what appear to be spider mites on my Crocosmia 'Lucifer' as well as a few different gladiolus. I've never had this problem before--anyone have experience to share? Thanks, Mary Gutierrez Seattle
