Evenly moist should do it. Most of zone 8 is humid enough though you might have to suppliment in Winter when it's indoors. Regards chris

Frequently planted Cordyline australis has been marketed as Spikes Dracaena here. It also has the botanical synonym Dracaena indivisa, resulting in continuing confusion in commerce with the much rarer and broader leaved Cordyline indivisa.

For the past several years I've had a potted majesty palm which has never looked happy. I cared for it diligently, but it grew slowly, the foliage looked kind of ratty, and nothing I did made it snap out of its funk. To top it off, I noticed about a week ago that it had become home to a sizable population of mealybugs. So I put it outside, right in time for our biggest cold snap of the season. It got down to 2F, and those mealybugs bought it big time. Of course, the plant itself is deader than a doornail, but so what? It's an example to all the rest of those laggards indoors. Shape up, or else.

Nancy - I've never seen any that were taller than most of the Red Sisters that are planted all over the place. Red Sister is sold everywhere, but the more interesting varieties are very hard to find. Searle Bros. sells quite a few of them, but unless you can buy wholesale from them, you'll have to wait until their next open house in October.
