Schefflera delavayi, also known as Delavay’s schefflera or Chinese umbrella tree, is a striking, evergreen shrub or small tree with large, palmate leaves and an exotic look, popular in shade and exotic gardens.

Origin

• Native to southwestern China (especially Yunnan and Sichuan), northern Myanmar (Burma) and adjacent parts of northern Vietnam.
• Grows naturally in subtropical mountain forests, moist valleys, canyons and undergrowth of mixed forests at altitudes of 1000–2800 meters.
• Adapted to cool, moist, shady conditions with high humidity and well-drained, humus-rich soils.

Care

• Grows as an upright, bushy shrub or small tree up to 3–6 metres high (often 2–4 m in cultivation) and wide; leaves large (up to 30–60 cm in diameter), palmate with 7–11 glossy, dark green leaflets, leathery and shiny.
• Prefers partial shade to shade (protected from bright midday sun); Full sun can scorch leaves in hot climates.
• Plant in moist but well-drained, humus-rich soil (neutral to slightly acidic, rich in organic matter such as leaf compost); Add mulch to retain moisture.
• Watering: regular and abundant in growing season (spring/summer) to keep soil consistently moist; moderate in winter; Does not tolerate dehydration or prolonged wet feet.
• Winter hardiness: very good for a Schefflera (USDA zones 8–10); tolerates frost down to about -10 to -12 °C (sometimes down to -15 °C with protection); In colder climates (such as the Netherlands), protect with mulch, fleece or overwinter as a container plant frost-free (cool but frost-free, 0–10 °C, light spot).
• Fertilization: light organic fertilizer or slow-release fertilizer during the growing season; Do not over-fertilize.
• Pruning: light in spring to maintain shape or remove damaged branches; tolerates pruning well and can become bushier.

Usage

• Mainly ornamental plant (ornamental): highly prized for its large, exotic, palmate leaves and tropical appearance; Perfect as an accent in shade gardens, jungle gardens, exotic borders or as a container plant on the terrace/patio.
• Combines well with ferns, hostas, rhododendrons and other large foliage plants; Provides structure and texture in semi-shaded areas.
