Care

Emerges very late in spring; mark location to avoid accidental digging. Deadhead spent blooms to encourage prolonged flowering.

Maintenance

Divide rarely; fleshy taproots resent disturbance. Staking typically not required for the dwarf 'Astra' series.

Cleanup

Cut stems back to base in late autumn or leave for winter interest and cut back in early spring.

Notes

Buds swell into balloon-like spheres before bursting open into star-shaped flowers.
