repeatflowering

Repeatflowering, also called remontant flowering, refers to the ability of a plant to produce flowers more than once within a growing season or across multiple seasons. This contrasts with plants that flower only once and then set seed or senesce. In horticulture, repeat flowering is a desirable trait because it extends the period of floral display.

The timing and frequency of bloom are influenced by genetics and environmental cues such as day length, temperature, and resource availability. Hormonal signals and the activity of floral meristems determine whether the shoot will continue producing flower primordia after an initial flush.

Pruning, deadheading, proper watering, and balanced nutrition can promote subsequent cycles of flowering in many species. In some plants, flowering occurs on new growth, so cutting back in late winter or early spring can stimulate a fresh display.

Common examples of repeat-flowering cultivated plants include many roses (remontant varieties), geraniums (pelargoniums), chrysanthemums, and a wide range of perennials and annuals that are bred for continuous bloom, such as lantana, petunias, and impatiens. Some shrubs and herbs also show repeat flowering under favorable conditions; others may have a more limited cycle depending on climate and cultivar.

Overall, repeatflowering is a key feature in garden planning, allowing longer or multiple periods of bloom and often influencing pruning and care schedules to maintain continuous floral display.
