White Yarrow

Best grown in lean, dry to medium, well-drained sandy loams, Yarrow plants prefer full sun. They do well in average garden soils and tolerate poor soils as long as drainage is good. Plants also tolerate hot, humid summers and drought; and if grown ornamentally, plants are best sited in locations protected from strong winds

Plant stems tend to flop, particularly in hot, humid climates or if grown in moist, rich soils. Consider cutting back the stems in late spring before flowering to reduce overall plant height. Cutting plants back to lateral flower buds after initial flowering will tidy the planting and encourage additional bloom. Plants may also be cut back to basal foliage after bloom. Divide clumps as needed (every 2-3 years) to maintain vitality of the planting. Plants spread aggressively by rhizomes and self-seeding, and can naturalize into substantial colonies if left unchecked
