Origanum, commonly known as oregano, is a perennial herb that grows best in well-drained soil, in a warm, sunny position. Small, white or mauve flowers appear in summer. Bees and bumblebees love oregano flowers.
Origanum vulgare has ovate, green leaves that are highly aromatic. The fresh leaves or dried leaves can be added to salads, roast meat and pasta sauce. It grows to a height of 40-60cm.

How and when to prune Oregano (Origanum ). Trim back in late summer after flowering to keep the plant compact and to stimulate regrowth.
Cut back old and dead stems to the base of the plant in early spring. New growth will appear again.
Can oregano survive winter. Oregano is hardy. In mild winters oregano will retain its leaves.
A container-grown oregano plant doesn’t like wet conditions during winter. So place it against a wall where it is sheltered from heavy rainfall. During very cold weather cover container-grown oregano with layers of garden fleece.
