Sambac species is supposed to be different and shouldn't get below 50Ã‚Â°F. At least 60's in winter with plenty of humidity (which will be a challenge). 'Maid of Orleans' is single flowered, lasting only one day, but is said to be free blooming year round with best blooms in spring. ( or was it growth?)
You're right about size though. One source said up to 7 FEET planted in the ground. and yep, I'll be growing it in a pot.
I think I'll have plenty of opportunities to take cuttings. If it's relatively easy to care for, this might make another holiday gift candidate.
