South African Sage Wood is a striking large shrub or multi-stemmed tree native to the rocky hillsides and forest margins of southern and eastern Africa. In zones 8-11, this evergreen can reach 12 feet tall and equally wide, though it may stretch to 26 feet in ideal conditions. From May through July, it produces masses of fragrant, showy cone-shaped flower spikes that attract butterflies and hummingbirds in abundance. The narrow, dark green leaves with their distinctive white-haired undersides and puckered veins give it architectural presence year-round. Hardy, drought-tolerant once established, and thriving in full sun with moderate water, it brings both structure and pollinator magnetism to warm-climate gardens.

Harden off propagated cuttings gradually before planting outdoors after the last frost. Space plants 12 feet apart or more, allowing for their mature width. In colder zones, wait until soil has warmed and frost risk has passed completely.
Prune heavily to maintain the shape and size you want; South African Sage Wood responds well to aggressive cutting and will regenerate vigorously. Regular pruning also encourages fuller, bushier growth and more prolific flowering.
