The most important genera include: calibrachoa (Calibrachoa×hybrida),
carnations (Dianthus caryophyllus), chrysanthemum (Chrysanthemum×gran-
diflora), New Guinea impatiens (Impatiens hawkeri), poinsettia (Euphorbia
pulcherrima), petunia (Petunia×hybrida), and zonal geranium (Pelargonium×
hortorum) which are grown as cut flowers, flowering potted plants, or bed-
ding plants. In this review, we describe the physiological, environmental,
and cultural processes involved in cutting production, postharvest, and
propagation.
