Overview

Elegia spp. is a genus of about 50 species of evergreen, rush-like perennials in the family Restionaceae, native to the winter-rainfall fynbos of the Western Cape of South Africa. Plants form dense clumps of erect, green, cylindrical stems 1-10 ft (0.3-3 m) tall, with the leaves reduced to papery brown sheaths at the nodes. Photosynthesis takes place in the stems, which carry whorls of slender, feathery branchlets in some species such as E. capensis. Plants are dioecious, with male and female flowers in brown, chaffy spikelets on separate plants. The clumps spread slowly by short rhizomes and stay evergreen year-round. Most species grow in nutrient-poor, acidic, sandy soils and depend on the seasonal wetting and drying of their fynbos habitat. They resprout from the rootstock after fire. Establishment from seed often requires smoke treatment to break dormancy, and plants establish poorly after root disturbance once settled.

Native Range

Elegia spp. is native to South Africa, almost entirely within the fynbos of the Western Cape, with a few species in the Eastern Cape. Plants grow on sandstone-derived, nutrient-poor sandy soils. The genus belongs to the Cape Floristic Region, a temperate flora noted for its high plant diversity.

Suggested Uses

Grown as architectural accents in coastal, Mediterranean, and water-wise gardens, and in large containers. The evergreen reed-like clumps appear in gravel gardens and as cut or dried stems for arrangements. Plants suit lean, sandy sites where many ornamentals fail.

How to Identify

Look for dense tufts of erect, green, leafless stems with papery brown sheaths at the nodes, resembling horsetails or reeds. Taller species carry whorls of slender, feathery side branches along the stems. Brown, chaffy flower spikelets on separate male and female plants confirm a member of the restio family.

Spring Summer

Flowering occurs mainly in spring and early summer, around September to December in the native range and spring in northern hemisphere cultivation. The brown, wind-pollinated spikelets are borne on separate male and female plants. The flowering stems persist on the plant for months.

Care & Maintenance

Care Guide

Plants grow in full sun in sharply drained, sandy, acidic soil with a pH near 4.5 to 6.5 and low fertility, mirroring their fynbos origin. They need good air movement and decline in rich soils and high phosphorus, which can be fatal. Young plants are watered through the growing season and kept on the dry side during summer dormancy for winter-rainfall species. Established clumps tolerate wind, coastal salt, and short dry spells. Plants recover slowly from transplanting and are left undisturbed once settled.

Pruning

Old flowering stems are cut at the base once they brown to keep clumps fresh. Dead stems are removed in spring before new growth emerges. Plants are not cut hard, as many restios do not regrow from old wood.
