• Winter hardy to USDA Zones 8-10. In St. Louis, grow in containers or tubs that are overwintered indoors or as year-round houseplants. Container plants may be grown as shrubs or trained as ornamental standards. Plants generally grow best when overwintering period is short. Since plants will tolerate some frost, consider leaving containers outside in fall until temperatures dip below 20 F. and return containers to a protected outdoor as soon as temperatures permit in spring.
