Hi Tim . I once grew Anisotome haastii for a street planting in Te Anau . They were planted in a 500mm high raised bed full of soil . They did really well for a few years and were often photographed . Usually labelled as a new Queen Anne's Lace of some sort . I think they flowered too well because they crashed and burned after 3 years . A.pilifera and Gingidia spp grow well with a cool root run and no afternoon sun . Grew Anisotome cauticola for many years and I feel this species deserves a chance . I will see if I can get a few pics for posting
They are flowering well this year and we have found Anisotome Valley so if you want a few seeds let me know
Doug -Will post "on the way there" pictures soon
