Situation Full sun preferred - successful in dappled shade but will need wide spacing.
Delphiniums are very hardy and tolerant of frosts.
They will stand and even benefit from winter freezing. Planting Plant in Spring and Autumn Give each Delphinium m -1m of ground. Keep young plants moist Support Staking is essential for best results If grown in a bed grow through raised sheep netting or other framework. Properly supported delphiniums will stand a lot of wind Don't plant right up against a tall wall - the wind will thrash them.
