Astrantia major 'primadonna' is an attractive bushy perennial which has an abundance of tall branching sprays of pale pink to deep wine flowers. Will thrive in both sun or shade in a border and makes excellent cut flowers.
|When to Sow||October to February|
|Where to Sow||
Sow indoors on the surface of moist compost filled pots or trays and cover the seeds with a very fine sprinkling of compost or vermiculite. Place in a warm position (temperature of 18-22°C for 2 to 4 weeks) followed by 2-4°C for 4 to 6 weeks and then return to the warmth.
Germination requires a warm/cold/warm cycle which mimics conditions in nature and can take several months.
We find that sowing late autumn/ early winter in a greenhouse provides the best conditions for germination.
|What to do next||When seedlings are large enough to handle, transplant into 7.5cm (3in) pots or trays and grow on in cooler conditions.|
|When all risk of frost has passed, acclimatise indoor raised seedlings to outdoor conditions over 7 to 10 days. Then transplant into final growing position planting them 45cm (18in) apart.|
|Water well until plants are established.|
|Deadhead to encourage further flowering.|
|Flowering period||May to September|
