Best grown in moist, rich, sandy-humusy, well-drained soils with a neutral pH in part shade. Consider raised plantings in areas of heavy clay soils to insure good drainage. Also best when planted in locations protected from winter winds and full sun. Benefits from a summer mulch or ground cover which will often help keep roots cool. Do not allow soils to dry out. Often slow to establish and is best left undisturbed once planted.

Noteworthy Characteristics

Daphnes are well known for their intensely fragrant flowers. This daphne hybrid is a cross between D. cneorum and D. caucasica.

Genus name originally used for laurel (Laurus nobilis) but later transferred to this genus. Originally, from the nymph of the same name from Greek mythology, but could come from an Indo-European word meaning odor.

The hybrid name burkwoodii honors the brothers Albert Burkwood (1890-?) and Arthur Burkwood (1888-1951), English nurserymen and plant hybridizers.

'Silveredge' is noted for its intensely fragrant pinkish-white flowers and its variegated foliage. It is a slow-growing, densely-branched, semi-evergreen to deciduous shrub which typically grows 3-4' (less frequently to 5') tall with a rounded, mounding habit. Features clusters of extremely fragrant, pinkish-white flowers in spring which are followed by tiny red drupes (1/3" wide) in fall. Small, dense, oblong, bright green leaves (to 1 1/2" long) with creamy-yellow to silvery margins often persist well into December with no fall color. Similar in appearance to the popular Daphne x burkwoodii 'Carol Mackie', except 'Silveredge' is reportedly somewhat more upright and vigorous.


Although many nurseries consider this plant to be winter hardy to USDA Zone 4, daphnes in the St. Louis area often suffer significant winter injury in severe winters, particularly if improperly planted in locations exposed to cold winter winds and full sun. Plants weakened by winter injury are more susceptible to disease problems. Potential diseases include leaf spots, canker, twig blight, crown rot and virus. Potential insect pests include aphids, mealy bugs and scale. Plants can be temperamental. Michael Dirr reports that daphnes sometimes die very quickly for "no explicable reason."


A small, rounded shrub which is quite effective in smaller gardens. Plant in shrub borders, woodland gardens or incorporate into foundation plantings. Has good specimen value.
