What are you looking for? I have ficus ben, rubber tree(big leaf kind), schefflera all are the variegated variety, I also have some Pride of Maderia, both variegated and non, I have Dragons Blood(draceana draco) and numerous palms. I had one variegated screw pine but I think it got too cold, now I'm without.

Trog, your Dracaena is actually Cordyline. It's sold in garden centers as annuals for summer gardens, (cold climates) but the good news is, Cordylines are tender perrenials and can live on for years, if cared for properly. The, well, not really bad news is, although Cordylines are related to Dracaenas, somehow affiliated, they are more difficult keeping indoors then say, (Corn Plant) D. fragens or (Dragon Tree,) D. marginata. Fertilize in summer..This type of Cordyline is slow-growing, but will grow in summer, slow down or halt in winter. Stop fertilizing after September, restart some time in Apr or when you see new growth. Good luck, Toni They are sun lovers, though will do fine in very bright light. They will rot if overwatered. Drainage holes are mandatory. They should be summered outdoors. Although tap water will suffice, they dote on rain. But once again, drainage is important. I've seen huge versions of Cordyline, (one that comes to mind had purple leaves,) $600.00! When mature, they are beautiful, thick-stiff leaves. Height and width depends on the species. Some grow 18" while others reach 6-8' tall.

I guess this depends on where your boundaries of "botany" are. To me, genetics are naturally part of botany and I don't see how to separate the two. Botany incorporates all sorts of biological fields, and isn't limited to "traditional" "old school" botany, including nomenclature, identification, discovery, and taxonomy. Some of the greatest botanists I know are geneticists, horticulturalists, agriculturalists, microbiologists, and biochemists ;o)
