How to grow
Cultivation
Grow in any moisture-retentive, well-drained soil in a sheltered position. Leaf colour is best in full sun which can be tolerated if soil is reliably moist. Leaf scorch can be caused by lack of soil moisture or excessive exposure. Suits container cultivation but attention to watering is needed in dry spells during the growing season.
