It has a flower and is assumed to be an outdoor plant. We live within four blocks of Monterey Bay in Ca. Generally they are hardy to about 20 . They flower more readily when they are somewhat rootbound, which is why they are more often grown in large pots or tubs. It should be potted in a mixture of sterile potting soil, peat moss, and sand with a liberal amount of bone meal added.
Excellent drainage is essential.
Keep the soil evenly moist except from November-February when the plant should be kept on the dry side. Plants are propagated by divisions and seed, neither of which is difficult. Divisions may take two years to reach blooming size, when grown from seed it will take from seven to ten years before you see your first flower.
