Also, The Lily Garden, as a general rule, does not grow and sell many LAs. When I went through their Asiatic listing, I did find two noted as being LA: Bight Diamond and Royal Sunset. Royal Sunset has a well established history of good and long garden hardiness and one that holds it's color very well in a higher temp. environment.
Concerning staking LAs, I still don't think it's necessary. I never have had to stake any of mine and they've survived 70 and 80 mile per hour winds without a problem except for some leaf damage. The purpose of planting the bulb a little deeper provides a little better anchoring--and in your climate zone it would also keep the roots cooler, especially during the first year. All lily bulbs (I think) will, over time, establish their own 'comfort' depth level which they prefer.
