Liriope graminifolia var. densiflora

The Liriope graminifolia var. densiflora is an excellent perennial ground cover for partial shade, hardy and drought-resistant. This plant slowly colonizes the space by forming grassy mats, including around tree roots, where the soil is often dry in summer. This liriope effectively covers the ground and is decorative in winter and comes alive with a charming summer to autumn flowering, more or less late, in spikes of small purple flowers. This relative of Ophiopogon has the same uses in the garden.

The Liriope graminifolia var. densiflora belongs to the Liliaceae or Asparagaceae family, depending on the classification. This species is native to the Asian understory, like many Liriopes. It has excellent cold resistance (-20°C). It prefers light, slightly acidic to neutral soil, moist but not excessive, although it can adapt to slightly limestone soils (enriched with compost) and drier conditions where its growth will be slowed down.

This herbaceous perennial forms clumps, with slowly spreading rhizomes, and its stems are almost non-existent. Its foliage persists throughout the year, even in winter. It forms a dense bouquet of upright, concave, bright green leaves. Over the years, it spreads to form large colonies in mats that reach 30 to 40 cm in height. The Liriope is never invasive. Its leaves are linear, measuring over 15 cm in length and less than 1 cm in width. Flowering occurs between July and October, depending on the climate. A very dry summer will delay flowering until the return of rain. The inflorescences are spikes that rarely protrude from the foliage. Their pinkish stems bear numerous small mauve to pinkish bell-shaped flowers. The flowering is followed by the formation of black fruits.

The Liriope graminifolia var. densiflora forms a large clump of attractive grass-like foliage throughout the year, even in winter, strong and dense enough to discourage "weeds". Strong, adaptable, and low-maintenance once established, it brings a touch of lushness and a well-groomed appearance to neglected areas of the garden. Plant it every 40 cm along a partially shaded path, at the base of a hedge, or under large trees with light foliage, and it will quickly create a superb and tidy carpet. It is also a plant that thrives in containers, on a window sill or balcony. It is so forgiving that it will tolerate watering neglect and thrive in gardens without gardeners or weekend gardens.
