S.macrophylla can cope with winter temperatures of -5c to -10c. S.macrophylla leaves are huge and and susceptable to wind damage. A south facing sheltered wall in dappled to strong light is best for this species. Wind protection is key and they make great greenhouse plants. Schefflera macrophylla is best described as a centrepiece specimen plant with its long petioles supporting broadly spreading leaves.
Schefflera can be evergreen shrubs, trees or climbers with long-stalked palmately divided leaves and, on mature plants only, panicles or racemes of small flowers followed by spherical fleshy fruits. hardy to -5c to -10c.
Grow in well-drained soil in sun or semi-shade. Young plants may need to be kept frost-free, but will survive outdoors in most areas once up to 1m or so, if sheltered from cold, drying winds.
