Pearly everlasting is an underappreciated North American native herb that deserves to be planted more often in gardens and landscapes. This easy-care perennial features lance-shape gray-green foliage that forms an attractive mound from spring all the way to autumn. Its long-lasting white flowers dry well, making them perfect for crafts projects. And because pearly everlasting attracts butterflies, it makes a great choice for butterfly and pollinator gardens. Pearly everlasting is fantastic in the middle or back of a border for its minimal care needs and fine texture.
Pearly Everlasting Overview
Where to Plant Pearly Everlasting
Pearly everlasting thrives in dry, sunny spots, tolerates rocky or poor soils, and makes a nice addition to rock gardens. As a prairie plant, this perennial is a natural choice for native-plant gardens, and it thrives alongside other sun-loving natives, including false indigo (Baptisia), butterfly weed (Asclepias tuberosa), coreopsis (Coreopsis), liatris (Liatris), garden phlox (Phlox paniculata), ironweed (Vernonia), and purple coneflower (Echinacea). Because of its spreading nature, pearly everlasting is more effective in informal and cottage-type gardens than formal ones.
You should also consider pearly everlasting for your butterfly or pollinator garden. Many species of pollinators love its flowers, and it acts as a host plant for painted lady butterflies. In fact, planting host plants (the plants caterpillars eat) is a more effective strategy for attracting butterflies than planting flowers that produce a lot of nectar.
Add pearly everlasting to your herb or cutting garden, too. Its flowers last surprisingly long when cut for bouquets. If you prefer to use them for dried-floral crafts (such as wreaths and swags), hang the flowers upside down in a warm, dry place for a couple of weeks to dry. You can also use the dried flowers for decorative potpourri.
How and When to Plant Pearly Everlasting
You can start pearly everlasting seeds directly in the garden in the fall or after the average last frost date in the spring. Lightly rake the planting site. Sow the tiny seeds on the soil surface as they need light to germinate. Keep them moist but not wet until seedlings emerge. The plant grows relatively quickly and may flower in its first year in the garden.
To plant nursery specimens in either spring or fall, dig a hole about the same width and depth as the planting container. Remove the plant and loosen the roots a bit from the root ball before placing in the hole. Backfill with soil, tamp lightly, and water well.
Space multiple plants 18 to 24 inches apart to allow for adequate air circulation.
Pearly Everlasting Care
Light
Grow pearly everlasting in hot, sunny spots where it gets at least six hours of direct sun each day for best blooms and garden performance. It will tolerate partial shade but will bloom less and exhibit a tendency to flop over instead of maintaining its mounding habit.
Soil and Water
Because pearly everlasting is native to poor, dry soils, it tolerates droughts and nutrient-deficient soil. That said, like most perennials, pearly everlasting grows and does best when watered regularly—especially during periods of drought or unseasonably hot weather. It also requires regular watering the first year after planting to help it get established in the garden and develop a strong root system.
Temperature and Humidity
Pearly everlasting prefers dry, sunny climates and performs at its best between 32 and 90 degrees F. Humidity doesn't affect the plant as long as it has adequate air circulation.
As a prairie native, it tolerates subzero temperatures in the winter without any special attention.
Fertilizer
Pearly everlasting thrives in most growing conditions and does not need fertilizing to flourish. In fact, given its tendency to spread, feeding the plant is discouraged.
Pruning
A low-maintenance perennial, pearly everlasting doesn't require much pruning. After it freezes in fall, you can cut it back to 3 or 4 inches tall or leave it standing for a little winter interest. Give it a trim in spring as new growth resumes. In fact, many gardeners find leaving the stems standing in winter and cutting them in early spring helps protect the newly emerging growth from hungry deer and rabbits.
Potting and Repotting Pearly Everlasting
The plant makes a good container plant and it’s an ideal way to enjoy pearly everlasting without worrying about its tendency to spread rampantly. Select a pot with large drainage holes and use well-draining potting soil. Keep in mind that potted plants, unlike plants in the landscape, require more frequent watering and fertilization.
Repot the plant when it becomes rootbound. Choose a container that's one size larger and fill with fresh potting soil. Remove the plant from its pot and tease the roots to loosen them. Place in the new container, backfill with soil and tamp down. Water well to remove any air pockets.
Despite its hardiness in areas with cold winters, when grown in pots, the roots of pearly everlasting are exposed to the cold. As a protective measure, winterize the pots by sinking the container into the ground. You can also place the container in a second, larger pot to create a planting silo that will insulate the roots from the cold.
Pests and Problems
Pearly everlasting does not suffer from significant pest and disease issues. The herb may host butterfly larvae, so the plant is susceptible to chewing damage from hungry caterpillars.
Because it spreads by underground stems, pearly everlasting can be a bit of a thug in the garden and behave aggressively if you water regularly and fertilize abundantly. Consider where you'll plant it and what its care regimen will be before adding it to your yard.
How to Propagate Pearly Everlasting
Propagate this herb by seed, cuttings, or division.
Division is the easiest method of propagation. Divide every 4 to 5 years in spring. Dig up an entire plant, divide it into sections, and replant in a suitable spot at the same depth as the original plant. Water well after planting.
To grow from cuttings: Fill a shallow tray with a lightly dampened sterile seed-starting mixture. In spring, take basal cuttings. In the early summer, take cuttings from stem tips. Use sharp bypass pruners to cut 4-inch-long plant cuttings with at least two sets of leaf nodes. Pinch off any flower buds and remove the lower leaves. Plant the cut end of the stem in the pre-mixed seed-starter after dipping it in rooting hormone. Place it in bright indirect light or under grow lights. Rooting has succeeded when you see new growth. When roots are strong, transplant them to planters filled with potting mix or outdoors.
To grow from seed: Before planting seeds, store them in a cool, dry spot in a sealed container. They don’t need to be pretreated, but you can place them in a plastic bag inside the refrigerator for a few weeks, which may speed germination. To start seeds indoors, sow them 6 to 8 weeks before your average last frost date. Fill pots with moistened potting mix and sow seeds on the surface of the soil. Cover with pots with plastic to maintain humidity. Keep the seeded pots warm (about 60 to 70 degrees F) and in indirect light. They should germinate within 14 to 28 days. Harden off when seedlings are about 2 inches tall.
Types of Pearly Everlasting
Common Pearly Everlasting
Common pearly everlasting (Anaphalis margaritacea var. cinnamomea) has wooly, white stems that support green-gray leaves covered in white hairs. The flowers are small and yellow surrounded by papery white bracts that dry exceptionally well. Zones 3-8
Japanese Pearly Everlasting
The dark gray foliage of Japanese pearly everlasting (Anaphalis margaritacea var. yedoensis) is silver-edged and flowers are larger than the species. Zones 4-8
Three-Veined Everlasting
Three-veined everlasting (Anaphalis triplinervis) grows to 3 feet tall and tolerates more moisture than the species. ‘Summer Snow’ is a popular dwarf variety that is good for edging. Zones 5-8
Pearly Everlasting Companion Plants
Bear's Breeches
Bear's breeches is grown for its glossy, large-leaved foliage that can appear jagged or spiny. This plant spikes tall geometric flowers with white petals and prickly purple bracts late spring into early summer.
Penstemon
Both pearly everlasting and penstemon do well in hot, dry spots and require little attention once established in the garden. Both are also excellent choices for attracting butterflies to the garden. Penstemon offers an eye-catching vertical shape thanks to its flower spikes, creating an attractive contrast to pearly everlasting's more mounded form.
Veronica
Easy and undemanding, veronica catches the eye in sunny gardens for many months. Some varieties have mats with loose clusters of saucer-shape flowers, while others group their star-shape or tubular flowers into tight erect spikes. A few veronica types bring elusive blue to the garden, but more often the flowers are purple or violet blue, rosy pink, or white.
