| Astrantia | Common name; Masterwort |
A hardy herbaceous border perennial suited to sun and shade.
The clusters of purple-red flowers and bracts that grow about 300mm (12”) high appear in July.
In an exposed position the plants may need supporting with twiggy sticks.
Week 13; Prick out the seedlings sown the previous autumn into 70mm (3”) pots and grow on in a coldframe until planting out time.
Week 35; Sow seeds in seed compost and place in a cold frame to germinate.
Week 35-40; Cut down the stems now if not done after flowering.
Now is also a suitable time to divide and replant established plants
Week 40; Plant out potted seedlings between now and March in any ordinary garden soil at 200-300mm (8”-12”) centers
A partially shaded position is generally best, but a sunny spot will do if the soil stays reasonably moist in summer.
