Just about everywhere you go along roads in the Powell River backcountry you'll find Pearly Everlasting (Anaphalis margaritaea). It’s nice to have a flower that’s almost a namesake: Margy, Margaret, margaritaea.
You can find Pearly Everlasting on rocky slopes, in open forest areas, clearings, meadows, fields; pretty much any sunny spot from low elevations to sub-alpine heights.
Like many other plants in the Aster family, it’s a perennial herb. Many straight stems rise from an underground rhizome (versus a root), allowing it to survive through the winter to regrow each spring.
The narrow lance-shaped leaves are greyish-green on top and white underneath. The round white flowers, looking much like handfuls of pearls, grow in clusters at the top of each stalk. When picked and dried, they last a long time in flower arrangements, pretty much “everlasting.” -- Margy
