Delphinium 'Astolat Group'
- Position: full sun
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: May - June
- Hardiness: fully hardy
Lovely tall spires packed with soft blush to deep pink flowers appear in late spring and early summer. Forming part of the Pacific Hybrids Series, they have been bred to withstand higher summer temperatures and have larger than average flowers on their stout stems. A classic cottage garden addition, it is useful for adding height and structural interest to the planting scheme.
- Garden care: Protect young foliage against slug and snail damage in spring. Stake with bamboo canes in mid-spring, before the flowers appear. During the growing season, apply a balanced liquid fertiliser every 2-3 weeks and wearing gloves cut back the faded flower-stems to a flowering side-shoot to encourage repeat flowering. At the end of autumn cut back and compost the faded flower-stems.
