Hi all, Thanks to Alberto for the really (as usual) informative introduction to Tigridia. I am interested to hear that Rigidella has now been included with Tigridia. I grow Tigridia pavonia and find it does very well in the ground here staying quite wet during its winter dormancy . In fact those in the ground do better than those in pots which I presume are drying out too much during summer. Tigridia (Rigidella) orthantha also tolerates moisture through winter dormancy. I grow the other species mentioned by Paul - chiapensis, dugesii, durangense, multiflora and vanhoutei as well as mexicana passiflora. I treat them all the same way- in pots which I keep out of the rain through winter dormancy. The first 5 species flower well and increase by bulb division and seed freely. I have never flowered mexicana passiflora which grows at 1000m in Mexico and clearly finds my climate a little cool. The bulbs are continuing to enlarge so I live in hope . I have given a couple of bulbs to friends in different climates this winter so hope they can produce flowers. I have raised T philippiana from ABA seed by courtesy of Julian Slade but have to admit they are not really happy- I dont have a lot of returns in their second season. Last summer I put some pollen of Rigidella orthantha onto Tigridia pavonia and managed to harvest 3 seeds. I had read of this hybrid in Brian Mathew's "Larger Bulbs" and thought it was worth a try. I will let you know if I get any germination. Seed for most of my species came from Southwest Native Seeds in Tucson which I am sure will be far easier for most of you to access than it is for me. I also managed to grow and flower the tiny irid Nemastylis tenuis nana from their seed but unfortunately wasnt able to maintain it in cultivation for very long. I would love to hear of any seed sources for the other species mentioned on Alberto's list. Cheers, Rob in Tasmania Zone 9 equivalent.
