Winter hardy to USDA Zones 10 to 11. In its native area, it tolerates a wide range of soil conditions from acidic to slightly alkaline and will grow in sand, loam or clay. It has moderate drought tolerance and poor salt tolerance and will grow in full sun to part shade. In the St. Louis area, it must be grown in containers which can be placed outside on decks and patios during warm weather or it can be grown indoors year-round in an area that receives bright, indirect light. When placed outside, avoid direct afternoon sun. In winter, plants benefit from misting to maintain higher humidity levels, but do not spray flowers. They are relatively trouble free, but watch for mealybugs, red spider mites and scale. Prune severely to 4 to 8 inches in spring to encourage new growth and increased bloom; remove spent flowers. Indoors, keep soil moderately moist, but not soggy. Feed monthly from March to September.
