Pycnanthemum incanum
Pycnanthemum incanum has oval leaves, borne on square stems, that have a minty aroma. and whorls of tiny white to lavender tubular flowers that are attractive to pollinators. The leaves surrounding the flowers silvery white highlights.
Flowering
From Late Summer TO Late Summer
Whorls of pink flowers with silvery bracts appear in late Summer
Propagating by seed
From Early Spring TO Mid Spring
Sow in a cold frame in Spring, onto moist, but drained seed compost. Barely cover seed. The ideal temp for germination (which may take approx. 2 weeks, but can take as long as 3 months) - or sow in situ in mid Spring. Transplant the seedlings when they are large enough to handle, and grow them on under glass. Harden them off before planting out in Summer
Planting
From Late Spring TO Early Summer
Plant out seedlings into a sunny, or partially sunny site in late Spring or early Summer, after hardening off the seedlings. Will grow in most soils, but moist, free-draining, loamy soil is preferred
Propagating by division
From Mid Spring TO Late Spring
Established clumps can be divided in Spring, and the divisions replanted where required.
