How to grow
Cultivation
Plant in an open spot with fertile, freely-draining soil and protect the young foliage against slug and snail damage. Add canes or stakes to support the plant as soon as foliage begins to appear, tying in as the plant grows. Apply a seaweed or balanced liquid fertiliser every 2-3 weeks. To encourage strong flower spikes thin shoots when 7cm high, leaving a minimum of 2-3 shoots on young plants and 5-7 shoots on established plants. See staking: perennials and delphinium cultivation for further advice
Propagation
Propagate by seed sown at 15-20°C in early spring
