Hello Brandon I live in Hawaii, and have been experimenting with lilies for about 5 years. Lilium formosanum, philippinense, wallichianum are all trumpets and grow with no problems. Orienpets (Oriental x trumpet) also seem very happy here. I have not found that they are especially sterile, and have many seedlings of tetraploid Orienpets. It seems that the main requirement in tropical areas is to grow the lilies from seed. An imported bulb that is accustomed to a cold season will not return the next year without refrigeration, but often the same variety grown from seed will return with no problem. Some require special treatment--for me, L. longiflorum needs a dry rest in August-September, or else it will keep growing from the top of the stem (Make a bulb in the air and keep growing) and never flower. Lilium Triumphator, a longiflorum hybrid, is an exception to most lilies and even imported bulbs grow and return with no problem, although I dry them out somewhat after blooming, too. The North American lily Society (NALS) has a good seed exchange every year around January (or later), and membership is worth it for the seed exchange alone. Just Google on NALS. Aloha!

The Oriental hybrids are also reported to be very tolerant of heat. Not sure if you were referring to these in particular, but the Orienpet types have done well here in south Louisiana They have been truly perennial while many other types just don't survive. These would be worth experimenting with in the tropics. The main drawback is that almost all of them are sterile (without embryo rescue) and one can't select better performing seedlings etc. I think even the initial species crosses had to be done with embryo rescue, but these aren't my specialty by any means. Another one that has done extremely well is 'Triumphator' which is an Oriental x longiflorum type. These go dormant in mid summer here, so it would be interesting to see how they adapt to year round hot weather. Tim Chapman
