The leaves are very attractive, and the flowers are small, but pretty when they are blooming. In my experience, does not like heat or dryness. May be best to grow it in partial shade if your area has hot summers (highs greater than 80 ºF, 27 ºC), and make sure it is watered during dry periods. When it wilts, the tips of leaflets dry out and turn crispy.
