Although this evergreen agapanthus may be planted in the ground in the warm winter climates of USDA Zones 8-10, it is best grown in tubs or containers in the zones 5 and lower area (Zones 5b-6a) where it is not winter hardy. This is a tender perennial that grows from a fleshy-rooted rhizome. For container plants, plant rhizome 1/2" below soil surface, keep soils consistently moist and provide moderate fertilization during the growing season (spring and summer). Plants bloom best when roots are pot-bound. Site containers in locations with afternoon shade. In fall prior to the first frost, remove containers to a bright, frost-free location for overwintering. Provide very limited water in winter (just enough to keep leaves from drying/wilting). Return containers outdoors in spring.
