Oh yeah- in full sun, they grow 1/2 an inch a day, its pretty amazing! The flowers are really cute too. If I lived somewhere where I could have them as groundcover, I would absolutely use them. People are always fascinated by them too, and want cuttings :-) You could even keep pieces of the plant in a cup of water; they grow roots eventually and flower great in the water (I think it stresses them a bit).
