Agrostemma githago 'Ocean Pearls' / White Corncockle / Seeds

A lovely hardy annual with grey/green leaves and large white flowers with speckled throats, from June to August/September.  Plants form a good branched shape and grow to a height of about 60cm.  They attract pollinators into the garden and make good cut flowers.  Plants look good in borders and are also suited to smaller courtyard gardens.

Corncockles grow best in a sunny position in poor well drained soil.  They are hardy and can withstand frost.  They self-seed but not necessarily in white after the first year. 

Pack of approx 100 seeds.  Sow directly into the ground in autumn or spring.  Sowing instructions and a colour photo are printed on the packet. 


Harmful if eaten.

Hardiness Hardy annual (RHS Hardiness H5)
Flowers June to August/September
Height To 60cm
Spread To 30cm
Conditions  Full sun and poor well drained soil

Sow the seeds 1-2cm deep directly into the ground in autumn (September/October) or spring (Feb to May).  Or sow indoors from January to early spring in a tray or small pots of compost, keep at 15-20C and germination takes 1- 3 weeks.  Plant out after hardening off.  


Plants grow in the spring, flower in summer and die back in autumn after flowering, when they can be cut back and removed.  Deadhead plants to prolong flowering and continue to deadhead until you remove the plants if you do not want them to self-seed.  In richer soils or in exposed gardens, plants may need staking to look their best.
