Growth—

Pycnanthemum pilosum is a very cold-hardy plant, tolerating winter temperatures falling to -20°c or lower[1]. Succeeds in most soils[2] but prefers a rich loamy soil in full sun or partial shade with plenty of moisture in the growing season[3]. Easily grown in average, dry to medium, well-drained soils in full sun to part shade, but flowering best in full sun[1]. A vigorous grower which can spread freely by rhizomes in optimum conditions. If naturalizing is unwanted, prune roots in spring with a spade to keep clumps from spreading[1]. All parts of the plant are very aromatic when crushed[1]. A good plant for attracting butterflies and bees[PFAF].

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.
