- Horticultural Group
- Perpetual flowering carnations are half-hardy evergreen perennials grown under glass for cut flowers and for exhibition. Given temperatures above 10 degrees, they can flower all year round, the blooms to 10cm across, sometimes scented
How to grow
Cultivation
Grow in containers in a peat-free compost with added perlite. When buds appear, feed with a high potassium liquid feed. Perpetual flowering carnations are often grown under glass all year but can be placed outside in summer. Stems will require staking. See staking perennials
Propagation
Propagate by cuttings taken from non-flowering stems; early spring is a good time to do this but cuttings can be taken any time from late winter through to late summer
Suggested planting locations and garden types
- Patio and container plants
- Conservatory and greenhouse
Pruning
Deadhead regularly to prolong flowering
Pests
Diseases
May be susceptible to powdery mildews, a rust, a virus and fusarium wilt
