lehtikasvi

Lehtikasvi is a Finnish term used in horticulture and botany to describe plants that are valued primarily for their leaves. It is not a taxonomic group; rather, it denotes a broad category of herbaceous species whose foliage is the main ornamental attribute. The word combines lehti (leaf) and kasvi (plant).

Description and scope: Lehtikasvi includes a wide range of growth forms, from groundcovers to upright perennials. Leaves may vary in size, shape, texture, and color, and may be evergreen or deciduous. In many cases flowering is present but secondary to the display of foliage, which is the defining feature for this category.

Habitat and distribution: The category encompasses both native and cultivated species across temperate regions. In gardens and landscapes, lehtikasvi are chosen for contrast, structure, and long-lasting leaf display, often regardless of flowering habit.

Cultivation and care: Requirements vary by species, but common considerations include well-drained soil and appropriate light conditions for the leaf type. Some lehtikasvi tolerate shade, others prefer sun. Propagation is typically by division, cuttings, or seeds, depending on the plant. Many are grown as ornamental perennials or indoor foliage plants and are valued for durability and visual texture.

Significance: In horticulture, lehtikasvi contribute to design through texture, color, and form. They are used as groundcovers, in borders, on containers, or as indoor displays, offering enduring greenery and structural interest.
