Elegia elephantina

Formerly called Chondropetalum elephantinum, now renamed Elegia elephantina, this tall South African perennial is part of a group of plants called Restio, still relatively unknown in Europe. Mainly native to the Cape Province, they resemble tall grasses, sedges, or rushes and are generally not very resistant to heavy frosts. Elegia elephantina forms a beautiful evergreen clump composed of slender stems punctuated with black nodes and topped in late summer with short spikes laden with dark seeds. Paired with grasses and sedges, this perennial creates magnificent compositions in mild climates. It is also a very attractive plant for the terrace,  well-suited for container gardening.

Elegia elephantina, also locally known as Grand Cape Rush, is a botanical species endemic to the fynbos, a type of South African heathland swept by the wind and regularly ravaged by fires. In this region of the Cape, three major plant families are gathered: proteas, heathers, and restios, which include Elegia elephantina.

This tall herbaceous perennial forms a clump of stems emerging from the stump, narrow at the base and widening towards the top. It can reach a height of 1m (3 ft 4 in) with a crown diameter of 1.20m (3 ft 11 in) in open ground under our climates. When conditions are optimal, this plant spreads laterally to form large clumps over 1m (3 ft 4 in) in diameter. It develops slender cylindrical stems that grow somewhat zigzagged, more swollen at the base and with a green-grey colour. Along its stems, at regular intervals, branches emerge from almost black nodes. The stems lack true leaves. This plant is dioecious, meaning there are male and female plants. Flowering occurs in summer, earlier or later depending on the climate, in the form of short brown spikes, followed by the formation of chocolate brown capsules that remain decorative on the plant for a long time.

Restio is not very hardy, especially in its early years, but it is not demanding, even in sandy and poor soil. Its tall grass-like silhouette speckled with black makes a strong impression in a naturalistic border, a minimalist setting, or on a contemporary-style terrace. A well-established plant will be able to withstand -8/-9°C (17.6/15.8 °F) occasionally, allowing it to be grown in open ground in mild climates. Drought tolerant and resistant to salt spray, it is particularly well-suited for coastal gardens. It can also be used in a very decorative way on the terrace, to be stored over winter in cold climates. Whether in the ground or in a pot, it always looks good in association with the amazing Boronia, ferns, Dierama, Miscanthus, Carex comans, or even Gomphostigma virgatum. Its flowers are also very beautiful in dried bouquets.
