Thanks, DrDawg!
I have a room that gets a bit less sun - it's a western exposure - but stays closer to 72, do you think that would be better for them? I'll likely get a supplemental light, but that won't be for a while, unfortunately. I know I'm not exactly in prime plumeria-growing habitat (ha! Not with the winter we had!) but I hope that with care I can see these gorgeous blooms for myself. Unfortunately a plane ticket to Hawaii isn't in the cards! It is driving me a bit crazy not taking care of them, but I've got some other houseplants I can baby until they wake up.
