I discovered this summer when I bought some flowers and hostas to dress up the yard and then got too attached to them to actually plant them that I like plants. They are nice to have around. Interesting, yet predictable. Beautiful, but not proud. They let you know what they need and they respond when you do something nice for them.
That first round of plants I bought has to stay out on the porch because they have bugs, but now I have two new plants that can stay inside with me, at least until I accidentally kill them. I got a poinsetta ('tis the season) and some sort of Madagascar Dragon something-or-other. (I have no idea what it is but it was a lot of plant for the money and it doesn't need a lot of light.) If things go well with these guys I'm hoping I can get some more!
