Growth—
Succeeds in most soils[1] but prefers a rich loamy soil in full sun or partial shade with plenty of moisture in the growing season[2]. Hardy to at least -15°c[2]. The correct name for this species should be P. tenuifolium. Schrad.[3]. The bruised leaves are very aromatic[2].
Propagation
Seed - sow spring or autumn in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If there are sufficient seeds they can be sown in an outdoor seedbed in mid spring. Division in spring.
