Pearly everlasting

Year-round

Pearly everlasting is a tough, low-water perennial native to the Pacific Northwest, including Oregon, and it does well in Portland's dry summers and mild winters. It spreads by underground rhizomes and its leaves are used by American lady butterfly caterpillars.

• Give it full sun and well-drained soil. Once it is established it does not need extra summer water, which fits Portland's dry summer pattern well.
• It spreads by rhizomes and can form a slowly widening patch over a few years, so give it room or plan to edge the bed back each year.
• American lady butterflies lay eggs on pearly everlasting and the caterpillars build small silk tents in the leaf tips, so a few chewed leaf tips in summer is the plant doing its job as a host plant, not a problem to fix.
• ASPCA does not have a specific entry for pearly everlasting or the Anaphalis genus in its toxic or non-toxic plant lists, so we cannot confirm a clean record either way. As general caution, discourage pets from chewing on it.

Fall

In fall the flower heads dry to a papery white and can be left standing for texture or cut for indoor arrangements.

• The dried, papery flower heads are the 'everlasting' part of the name and hold their look well into fall, so many gardeners leave them standing instead of deadheading.
• Fall is a good time to divide crowded clumps if the patch has spread further than you want.
• Hold off on heavy pruning once early fall arrives. New growth stimulated too late in the season can get damaged by the first frost.

Leaving the papery seed heads standing through fall gives an HOA-conscious front bed some structure instead of bare dirt.

Winter

Portland's zone 8b winters are mild enough that pearly everlasting needs no special winter protection. The only choice is whether to leave or cut back the dried stems.

• The plant is dormant and hardy well past Portland's typical winter lows, so no mulching or covering is needed here.
• Leaving the dried stems standing keeps seed heads and structure through winter, or you can cut them back now instead of waiting for spring.
• Rain, not cold, is Portland's main winter challenge for this plant, so good drainage going into fall matters more than any frost protection.

Cutting back the dried stems for a clean winter silhouette, rather than leaving them standing, is an HOA-conscious option where front-yard tidiness matters most.

Spring

Late winter through early spring is the best time to cut back last year's dried stems before new growth starts.

• Cut old flower stalks and foliage down to a few inches above the ground in late winter or very early spring, before new shoots come up.
• This clears space for the new rhizome shoots coming up from the base and keeps the front bed looking maintained.
• New spring growth starts low and silvery green. Full-size flower stalks do not show up until later in summer.

Cutting back the dead winter stems in early spring is an HOA-friendly way to keep the front bed looking maintained before new growth fills in.

Summer

Pearly everlasting blooms mid to late summer with clusters of small white, papery flowers that pollinators and butterflies use.

• Deadheading spent flower clusters gives a tidier look, but leaving some flowers is fine too and keeps feeding pollinators longer.
• Water only during extended dry spells. This plant is built for Portland's dry summer, and extra water raises the risk of the base rotting.
• Check leaf tips for small silk-tent shelters. Those are American lady caterpillars using the plant as a host, and it is a good sign for the garden.

Deadheading spent blooms partway through summer is an HOA-friendly way to keep the front yard looking tidy.
