Pearly Everlasting

Anaphalis margaritacea ( Pearly Everlasting )
A fast growing to invasive, rhizomatous, dense clumping perennial, reaching a maximum size of 4 x 4 ( rarely over 3 ) feet, that is native to North America ( from Fairbanks, Alaska to far southwest Northwest Territories to Moosonee, Ontario to Labrador; south to central California to Colorado to central Minnesota to northern Indiana to Maryland ) and eastern Asia. It is very beautiful and is useful in the landscape where it has room to spread. It is found on sand flats, old fields and roadsides in the wild. It has naturalized in North America to as far north as Moosonee, Ontario.
The lance-shaped leaves, up to 5.5 x 0.8 inches in size, are whitish-gray.
The abundant, white flowers, up to 0.3 inches across, are borne on loose heads, up to 2.5 inches wide, during late summer to early autumn. The flowers attract butterflies.
Hardy zones 2 to 7 in full sun on very well drained soil. Moderately drought tolerant and also poor soil tolerant, too much moisture may cause rot during winter. Deadhead to encourage repeat blooming, plants can be cut to ground during late fall. Clumps should be divided every 3 years during autumn or spring to maintain vigor. It is easily sown from seed sown during mid-summer; they usually bloom the following year.
