Corncockle Garden Wildflower Seeds

Agrostemma githago

Other names: corn pink, zizany, corn campion, githage

A pink and powerful annual that will bring a unique vibrancy to any garden. Brought to the UK during the Iron Age, it is now all but extinct, modern farming has sought to destroy the corncockle for its toxic qualities. The seed and leaves are in fact poisonous – and if ingested in large quantities can be deadly!

But in the past, this dangerous little flower has been used as a symbol of revolution (hence why we love it!) It even gets a mention in Shakespeare’s Coriolanus as he talks of “the cockle of rebellion”.

Their thick stems make them perfect for a cutting arrangement or pinned to a lapel as a mark of revolution!

How to Plant

Cheap and Easy Method:

Scatter the seeds directly onto bare soil. Clear the area of any debris and lightly rake the soil to create a loose surface. Evenly broadcast the seeds, then lightly rake again to ensure good seed-to-soil contact.

More Involved Method:

Use a terram membrane to suppress unwanted vegetation. Add a layer of soil over the membrane, sow the seeds evenly, and press them in gently.
