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
