A Sculptural Yucca
Yucca gigantea, also sold as Yucca elephantipes, is a tender, tree-like yucca grown outdoors in warm climates and widely kept as a houseplant or conservatory subject elsewhere. It carries the family's trademark stiff, sword-shaped leaves atop one or more slender trunks, lending an architectural presence to a room.

Native Range
This species is native to Mexico and Central America, part of the wider Yucca genus within the Asparagaceae family. In cultivation it has become a familiar sight as an indoor or conservatory specimen in cooler regions where it cannot survive outdoors year-round.

Light, Water, Feeding
Give it a sunny position all year, ideally a south-facing window in winter and an east- or west-facing spot in summer, with light shade from the harshest midday sun and good ventilation to avoid overheating. Grow it in well-drained, loam-based compost with added grit, watering freely and feeding with a balanced liquid fertiliser during active growth from spring into early autumn, then watering only sparingly through winter. It can spend late spring to summer outdoors in a sheltered spot once settled and stable against wind, but should come back indoors before cold weather, tolerating a minimum night temperature of around 7°C.

Cuttings, Suckers, Seed
New plants can be raised from seed sown in spring at 19–24°C, though flowers often need hand-pollination to set seed in the first place. Rooted suckers can be detached and potted on in spring, or root cuttings taken in winter; stem cuttings more generally are placed in coarse sandy compost in a propagator with bottom heat of at least 18°C.

Trunks and Rosettes
Left to mature, this yucca becomes a large, upright shrub or small tree, often sending up several trunks from near ground level with sparse branching. Its narrow, leathery leaves can reach up to a metre in length, and mature plants produce flowering spikes up to a metre long, carrying large numbers of hanging, creamy-white blooms in summer and autumn.

Aphids and Snails
The main pests to watch for are aphids, which tend to settle on the flower spikes, and snails, which can chew at the leaves. Yucca leaf spot disease is also a possibility worth checking for on the foliage.

Pruning as Needed
Pruning is not generally required; simply remove damaged leaves and spent flower spikes as necessary in spring. Indoors, turn the plant regularly so it does not lean or grow lopsided toward the light, and if it has grown too tall it can be cut back by around half once growth resumes in spring, with the removed top section usable for propagation.
