Delphinium 'Galahad' (Pacific Hybrids Series)
delphinium
- Position: full sun
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: June and July
- Hardiness: fully hardy
Branching stems support the spires of glistening, pure white flowers, which glow like illuminated candles arising from mounds of rich green foliage. Prolong the flowering period by cutting back the central flowerspike to its base after is past its best, as this will encourage the smaller, lateral shoots to flourish. - Garden care: For best results, choose an open spot away from taller plants. Stake with bamboo canes as they start to shoot upwards in mid-spring and protect young foliage against slug and snail damage. 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.
