It is a poor indoor plant and when keeping it small it does not develop many branches. Indoors susceptible to mites. And it needs full sun to color up the leaves.
Looking at Palmbobs photos i might have the red leafed form if there is a real 'red leafed form' I only say that since i bought mine many many years ago as a seedling at a drug store.Seems unlikely that it would be anything other than the generic plant.The red leaf might be cultural. More humidity and sun? Something. Deciduous outdoors for me. They grow ok on mild summer temps.Check out the Palmbob photo of one growing in front of Birches. Desert heat welcome, but not needed!

It seems to be pretty drought tolerant as a bonsai, too. As it ages, the roots can slowly be moved up and out of the soil making an incredibly interesting display of fat, twisted, sausage-like roots. Planted in the ground, as I did in my old yard, it grows slowly but steadily. It still forms an ornamental fat, round trunk base at first, but after 7-10 years the rest of the trunk seems to catch up with it and the swelling becomes less prominen... read more
