Care notes
CultivationGrow 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
PruningNo pruning required, but cut back by half if plants become leggy to encourage bushier growth and potentially a new flush of flowers
PropagationPropagate 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
Pest resistanceMay be susceptible to slugs, snails and aphids
Disease resistanceMay be susceptible to root rot and powdery mildews
