What are the categories of sensitive, moving plants that you know of, besides the carnivorous ones?
They are neat because they are animal-like.
I had some small, seedling sensitive plants that are native to the Northeast USA and which I grew from seed. They were neat, but it was hard to germinate them. They were like Mimosa Pudica except that they did not have prickers. One variety was Desmanthus Illinoensis, or the Illinois Bundleflower.
The neatest moving plant is the Dancing Plant, or Telegraph Plant, Codariocalyx motorius, which grows in Thailand:
There is a cactus that throws its spines, but I don't think that would be a good houseplant.
Lotuses open and close at sunrise and sunset., and there must be other ones that do too.
Are there varieties of the Australian Stylidium, with its moving flower, that don't kill creatures?
