Allium hollandicum Aflatunense / Seeds

A tall and enduringly beautiful Allium, from which so many varieties have been bred.  Tall purple flowerheads, from 1m to 1.5m tall, come out in mid-May to June and last well as a cut and dried flower.  These seeds produce lots of natural variation in flower colour (which is why they are popular for breeding), so you shouldg et pale purple to deep lilac flower colours. They look good planted together in groups.

This Allium likes sun and well-drained soil. 


Pack of 20 seeds.  Sow in the autumn/winter in a cold frame or against a north facing wall and the seeds will germinate in the spring onwards once dormancy is broken.  Or sow seeds in spring/summer including four weeks in a fridge.  Germination is erratic, so sow more than you need.  Sowing instructions and a colour photo are printed on the packet.

Sow Sow October-February in moist seed compost, and overwinter in a coldframe or outside wall, with a clear glass cover.   The cold breaks seed dormancy.  Seeds germinate in the spring onwards, some taking a year or more.   Or sow March-September in a tray of seed compost (just cover with compost) and place in the fridge for 4 weeks in a sealed bag and then outside. Seeds emerge one by one throughout the summer and into next spring.  Pot on as seedlings emerge and plant out after the last frost in a sunny well drained spot.
Grow Plants start flowering from the second season.  Tidy up faded flower stalks and leaves after flowering.  Plants are deciduous and die down in winter, and start growing again in spring.  Mature plants have offsets on the sides of the bulbs, which can be removed in winter and grown on into new plants.
