I'm curious...do your local plant supply stores not carry them? If you want to grow some in pots - look for/ask for 'Bloomingdale hybrids'. They are very double and look deliciously exotic!

They're suitable for zones 9-10 so you should be able to grow them with a bit of temperature management. (Ice cubes on the soil??)

BTW - check with your local stores - you might just be too early in asking. Try again in August and toward September.

Another off-beat possible is to ask on the Hawaiian Forum - although they are further north of the Equator than you are.

Good luck with your search.

Hmm. Maybe it is too early. We have a Home Depot here and I always come across others online who bought their bulbs there. I hope they do have it, they are amazing plants.
