Sensitive Plant! Cool!
Probably best grown as a houseplant or in a greenhouse, though it could probably go out in part shade in the summer. Indoors, keep it in a sunny window. Let the top 1/2 cm of compost get dry before watering--but remember that that can happen quickly! Feed with any good houseplant food. If it likes where it is, it will form cute, fuzzy pink flowers. Be sure to keep tight control of any seeds that form, though--it can become a terrible thorny weed in a greenhouse, or even (until frost) outdoors!
