Care in one minute
Site: sun to light afternoon shade in hot summers.
Soil and pH: well‑drained sandy or loamy soils; acidic to neutral.
Watering: steady moisture in spring; allow to dry slightly between waterings later.
Feeding: light feeding only; excess fertility promotes flopping.
Grooming: deadhead; shear after the first flush to tidy and encourage rebloom.
Overwintering: none needed where hardy; ensure winter drainage.
Watch‑outs
- Foliage can scorch in extreme summer heat.
- Sprawls in moist or fertile soils.
- Crown rot possible without drainage.
