Reptile, as long as you have good light, and winter humidity, (summer also) they're farily easy to grow.
I've never grown this plant from seed, but it'd take many years before it was old enough to flower. They say at least 7 yrs old. I'm sure it makes a difference where on resides, too..for instance if one lived in Fl or Ca it'd grow faster than it does say in z5. My zone.
If you're sure the nursery has them in, 40 miles isn't all that bad, and you might find something else that catches your eye, too..I'd phone first to make sure they had them available, and the cost. Toni
