How to Grow

Cultivation

Grow in moist but well-drained, fertile, slightly acidic soil in a sunny position when the risk of frost has passed. Tolerates shady areas if soil conditions are suitable. Feed with a suitable multi-purpose plant food throughout the growing season

Propagation

Propagate by seed stem cuttings or seed indoors. Transplant to desired location outdoors after the risk of frost has passed. Dislikes root disturbance, so if growing from seed, plant in biodegradable pots which can be transplanted directly into the ground without disturbing the roots

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Hanging Basket
  • Patio and container plants
  • Low Maintenance
  • Flower borders and beds
  • Garden edging

Pruning

No pruning required, but cut back by half if plants become leggy to encourage bushier growth and potentially a new flush of flowers

Pests

May be susceptible to slugs, snails and aphids

Diseases

May be susceptible to root rot and powdery mildews
