Plant height — Crocosmia

The plant height trait in Crocosmia is determined by varietal characteristics and growing conditions. Compact forms reach 40–60 cm, while tall cultivars can exceed 120 cm. The final value is significantly influenced by the corm planting dates and agrotechnical conditions that affect the development of vegetative mass.

Plant height is a determining factor when planning ornamental plantings and organizing cut flower production. Low-growing cultivars are used in the foreground of mixed borders, while tall-growing ones require protection from wind loads to maintain the stability of the flower stalks. The optimal stem length for use in bouquets depends on the cultivar and the developmental stage of the plant.
