Growing it

Propagation: seed
When to plant: spring, autumn
Overwintering: In colder climates, apply a light mulch to protect the crown from freezing and thawing cycles. Ensure the soil remains well drained to prevent winter rot.
In containers: They grow well in pots at least 20 cm deep, provided the soil is gritty and fast draining.

Direct Sowing

1. Sow seeds directly into the garden in early spring or autumn.
2. Press seeds into the surface as they need light to germinate.
3. Keep the soil lightly moist until seedlings emerge.

Pair these with low growing annuals to hide the poppy foliage as it begins to decline in mid summer.
