How to Identify
A short lived poppy plant. It is a herb. It grows 100 cm high and spreads 40 cm wide. The stems are branching. The leaves are blue-green. They have lobes along the stalk and are finely hairy. There are teeth along the edge. The flowers are yellow or orange and 5 cm wide. The fruit are narrow, curved seed pods. They are 30 cm long.
How to Grow
Easily grown in any good well-drained soil. Requires a very well-drained poor soil. Prefers a hot dry position and dislikes shade. A very ornamental but short-lived perennial, it is hardy to about -10°c. Plants are resentful of root disturbance and should be placed in their final positions as soon as possible. Flowers are produced in the first year from seed.
Propagation: Sow seed in mid-spring or autumn in a cold frame. A period of cold stratification improves germination rates. Prick seedlings into individual pots as soon as they are large enough to handle and grow on under glass for at least the first winter. Plant out into permanent positions in late spring or early summer, after the last expected frosts. Where seed is plentiful, a direct outdoor sowing in situ in mid-spring is worth attempting.
Medicinal Uses
Used as a poultice.
Other Uses
Oil pressed from the seed burns cleanly and is used as a fuel for lighting. It is also used in soap making.
