SCIENTIFIC NAME: Tagetes erecta

FAMILY: Asteraceae (Compositae)
TYPE: annual
LEAVES: opposite, 5"-6" long, pinnately divided into lanceolate segments with serrate margins, aromatic (unpleasant odor for many people)

SEASON OF BLOOM: spring to mid-summer, declining thereafter
GROWTH HABIT: 1' to 4', erect to rounded
SOIL: moist, well drained, infertile (high fertility encourages vegetative growth and reduced flowering)
SUN: full sun to part shade, extreme heat reduces flowering
UTILIZATION: bedding and edging, cut flowers; cultivar selection is important for heat, pest, and disease tolerance; however, no cultivar will provide good color without high maintenance--use for spring color or plant in late summer for fall color until frost or substitute Melampodium paludosum or Zinnia angustifolia
DISEASES: Botrytis--deadheading is necessary
INSECTS AND RELATED PESTS: spider mites common, leafhoppers, slugs
PROPAGATION: seed
