Marshmallow
Yarrow Seeds
Achillea ptarmica
Marshmallow yarrow blooms heavily, from late spring to late summer, with double sugar-white flowers. Drought and heat tolerant, compact, 12 in. tall plants bloom the first year. Marshmallow is one of the best yarrows for planting in containers. Winter hardy to zone 3.
Growing Marshmallow Yarrow Seeds
Plant Yarrow Seeds: Sow yarrow seed in cell packs or flats, press into soil, do not cover. Light aids germination. Kept at 70° F., germination in 14-28 days. Can direct sow yarrow seeds into prepared seed beds thinly, in rows spaced 24 in. apart. Thin seedlings to 2-3 ft. apart.
Grow Yarrow: Full sun. Drought tolerant once established, best appearance with some summer water. Average to poor soil, good drainage. Plants tolerate salt, ideal perennial for coastal landscapes. Excellent cut flowers, fresh or dried. Cut plants back by half when flowers fade to stimulate repeat bloom. Divide when plants become crowded. Yarrow is deer and rabbit resistant. Flowers attract butterflies and beneficial insects. Easy to grow.
