Plant Notes

Care Guide:
Grow in rich, moisture-retentive but well-drained soil in full sun. Mulch crowns in autumn. Remove spent flower stems to prevent seed set. Less hardy forms are best containerised and overwintered under cover — check hardiness before planting out.
In containers, repot one size up every two to three years; water and feed from spring to early autumn. Divide in spring when pot-bound. -
Good to Know:
Pollinator-friendly — the flowers attract bees.
Reliable in a sheltered, well-drained spot; less hardy forms need winter protection.
⚠️ Humans & Pets: Harmful if eaten. (Toxic to dogs and cats.) -
