How to grow

Cultivation In frost-prone areas, grow young specimens in full light as houseplants or under glass at 5-15?C in loam-based potting compost such as John Innes No. 2, water moderately and apply a balanced liquid fertilizer monthly while in growth, water sparingly in winter, and pot on or top-dress in spring - for more advice, see palm cultivation indoors; in frost-free areas, grow in well-drained soil in full sun; will tolerate poor, dry soil, and though frost-tender will survive short periods at 0?C - for more advice, see palm cultivation outdoors

Propagation Sow seed at 23-27?C in spring

Suggested planting locations and garden types Drought Resistant Architectural Sub-tropical Patio & Container Plants
