alum root 'Silver Gumdrop'

Grow in fertile, humus-rich, moist but well-drained soil, in partial or full shade, and mulch every year; the rootstock tends to push upwards, so every few years, in late summer or early autumn, divide and re-plant with only the crown above ground

No pruning required, but old leaves and flower stems may be removed to improve appearance

Propagate by division in late summer or early autumn

Prone to vine weevils and leaf and bud eelworm

May be affected by heuchera rust
