Surprisingly, there are orchids that will tolerate and flower under very
high heat and light conditions, particularly some of the Caribbean-derived
hybrids. You might tell her to try equitant oncidiums – they've got
brilliantly colored little flowers, and the plants are usually only about
six inches tall. They have to be watered every day; and it helps to raise
the humidity. Krull-Smith Orchids in Apopka, Fla, has some nice ones they
mail-order.
Hey, Dan(ny) – don't be so quick to dismiss orchids. They're tons easier
than you (and most of the world) think. I kill African violets, but I can
grow orchids. Seriously, she might do fine with them under those
conditions. It'd only cost her about $15 to find out.
