Cultivation
''Achimenes'' species and hybrids are commonly grown as greenhouse plants, or outdoors as bedding plants in subtropical regions. The species have been extensively
hybridized, with many of the hybrids involving the large-flowered species ''A. grandiflora'' and ''A. longiflora''. Many of the species and their hybrids have large, brightly colored flowers and are cultivated as ornamental greenhouse and bedding plants. They are generally easy to grow as long as their basic requirements are met: a rich well-drained soil on the acid side, bright indirect light, warmth, constant moisture, and high humidity. They have a winter dormancy and overwinter as scaly rhizomes, which should be kept dry until they sprout again in the spring. Some of the species and their hybrids are moderately hardy and can be grown outdoors year-round in zone 8, or even zone 7 with protection.
