I have Eulophia keithii with deciduous above-ground pseudobulbs. I am looking for tuberous species and a source for them. There are a great many species of Eulophia in South Africa. I also have success with Bletia purpurea (Central American) on the windowsill while not being stored dormant out of sight, and also Bletilla striata and ochracea outdoors planted in my zone 7 garden. I'm enjoying the posts greatly. Bonaventure Magrys Cliffwood Beach, NJ USA zone 7
