Growing Eurybia divaricata

Latin Name Pronunciation: yoor-rib' ee-uh

Eurybia species are almost exclusively North American native plants adapted to various habitats. The eastern woodland species, such as E. divaricata, grows in forests and woodland edges, often in rocky, shallow soil and on slopes where many other plants struggle. These tough, somewhat rhizomatous plants withstand drought and harsh conditions, freely self-sow, and are good, low-maintenance choices for pollinator gardens and for naturalizing in shady situations, forming a ground cover.

Light: Naturally grows in part shade to full shade, but some morning sun is desirable as well.

Soil: Plants require good drainage and are adaptable to a wide range of soil types and to average garden soil. Eurybia divaricata grows well in shallow, rocky soil with some organic content provided by leaf litter. Plants will not tolerate waterlogged soil. A slightly acidic pH is preferred, but not entirely necessary. Mulch with dried leaves, hardwood bark, or Pine bark chips until plants fill in.

Watering: Native to dry, open woodlands, once established this plant appreciates a drink during times of drought, which helps to promote flowering. Otherwise needs little or no supplemental water, except in extreme conditions. In situations with more sun, provide more moisture.

Fertilizer: A top-dressing of compost in spring is appreciated. Decomposed leaves are ideal; fertilizer is rarely necessary.

Pests/Diseases: Not often bothered by pests or diseases. Susceptible to root rot in waterlogged soil; possible powdery mildew if crowded—provide good air circulation.

Dividing/Transplanting: Divide or transplant in spring, preferably on a mild overcast day. Gently dig up the clump and carefully separate portions by hand or cut with a sharp knife or pruners. Replant and water well to promote establishment.

Companions: Pennsylvania sedge (Carex pensylvanica), Marginal Wood Fern (Dryopteris marginalis), Blue-stem Goldenrod (Solidago caesia), and Christmas Fern (Polystichum acrostichoides) are natural companions.

Continuing Care: Planted in a woodland garden or situation similar to its preferred habitat, this is the ultimate low-maintenance plant. Neat clumps of green, heart-shaped, basal foliage remain throughout the winter and should not be cut back. Small seeds are valuable food for songbirds and small mammals, so let dried bloom stems remain standing until spring, at which time they can be cut down to make way for new growth. Or, if you wish to recruit more plants, simply press seeds into bare soil in fall, or shake stems to release seeds on fluffy parachutes into the air. Eurybia divaricata and other woodland species depend on decomposing leaves, so you can even leave the leaves where they fall. These plants spread by rhizomes and can be dug and transplanted in spring.
