Plante vivace

Une plante vivace est une plante qui vit plus de deux ans et qui repousse d’une année à l’autre grâce à ses organes pérennes, souvent souterrains.

A perennial plant lives more than two years and regrows each season from its persistent organs. In horticulture, the term often refers to herbaceous plants whose aerial parts die back in winter.

What it is

A perennial plant is defined botanically as a plant that lives for more than two years. Horticulturally, it typically refers to herbaceous plants that survive winter through underground organs like roots, rhizomes, or bulbs, then produce new shoots in spring.

Why it matters

Perennials are fundamental to gardening because they return year after year, unlike annuals that complete their life cycle in one season. This distinction helps gardeners plan for long-term landscapes, as perennials require less frequent replanting but need proper care for overwintering.

Key details

Common examples include strawberry, rosemary, and agapanthus. Many perennials are planted with the expectation they will last several seasons; their maintenance varies by species, often involving pruning after flowering or in late winter, depending on hardiness.
