Pearly everlasting (Anaphalis margaritacea)
Pearly everlasting (Anaphalis margaritacea) offers silvery foliage and fluffy white blooms, ideal for low-maintenance, dry native plantings.
Complete Plant Information
Overview
Pearly everlasting, scientifically known as Anaphalis margaritacea, is a distinguished North American native valued for its striking, year-round silver-gray foliage and long-lasting late-summer blooms. This herbaceous perennial forms upright clumps, making it an excellent textural addition to dry garden settings where many showier plants struggle. Gardeners appreciate this species for its robust nature and its suitability for creating striking prairie or meadow looks alongside brighter flowering companions.
The allure of Anaphalis margaritacea lies in its woolly, silver-gray leaves which contrast beautifully with the tiny, pure white flowers that hold their shape well, both on the plant and when dried. It thrives in conditions that mimic its native dry, gravelly habitats, signifying its incredibly low maintenance requirements once established.
As a low-effort standout, Pearly everlasting provides texture and subtle color from July through August. Its resilience and ease of care make Anaphalis margaritacea a functional choice for ecologically minded landscapes or challenging sunny, dry spots in the perennial border.

How to Grow
For successful establishment, plant Pearly everlasting in spring or fall. This species thrives best in average, medium, well-drained soil. Though it tolerates poor, nutrient-deficient soils, ensure sharp drainage is present, as wet feet are detrimental throughout the season. The plant prefers full sun but manages well with partial afternoon shade.
Watering requirements for Anaphalis margaritacea are medium; during establishment, water regularly to encourage deep root growth. Once mature, this species is quite drought tolerant, especially when situated in sandier soil conditions. Fertilization is generally unnecessary; amending rich soil can actually encourage floppier growth.
Maintenance is minimal, fitting its “Low” level rating. Deadheading spent flower clusters is often omitted since the fluffy heads are prized for drying, but trimming back old stalks in early spring allows for the emergence of fresh, silver foliage. As Pearly everlasting is stoloniferous, monitor its spread, especially in ideal, rich conditions.
Landscape Uses
Anaphalis margaritacea excels where drier, well-drained conditions prevail. Its suggested use as a plant to naturalize makes it perfect for large drifts in dry meadows or prairies, creating an informal, sweeping texture with its silver leaves mingling with taller grasses or wildflowers.
In designed spaces, Pearly everlasting works wonderfully in the perennial border, especially when positioned among plants boasting vibrant, warm colors. The cool, silvery foliage of Anaphalis margaritacea provides excellent visual relief and contrast against scarlet bee balm or purple coneflowers. It is also highly effective in native plantings where resilience and low input are priorities.

Potential Problems
While Pearly everlasting generally faces no serious insect or disease problems, gardeners should watch for potential damage from caterpillars that may chew on the leaves. The primary cultural consideration is its tendency to spread. Since Anaphalis margaritacea is a stoloniferous plant, it can become aggressive under optimum growing conditions, requiring occasional root pruning or management to keep it confined to its designated space.

Companion Planting
When selecting partners for Anaphalis margaritacea, focus on plants that share its need for well-drained soil and full sun exposure, particularly those providing strong contrasting colors. Excellent companions include plants with deep purple or rusty red tones, such as Russian Sage (Perovskia atriplicifolia) or Rudbeckia species, whose warm hues make the silver foliage of the Pearly everlasting truly pop. Consider incorporating native prairie grasses that enjoy similar lean soil conditions to enhance the naturalized effect this species achieves so well.
Wildlife Benefits
The late-season bloom period of Pearly everlasting offers a valuable nectar source when many spring and early summer flowers have faded. While not primarily known as a powerhouse pollinator magnet, its small composite flowers attract various small beneficial insects and generalist pollinators seeking late forage. Furthermore, as a native North American plant, it provides structural habitat elements suitable for certain beneficial insect populations across the growing season in native plantings.
