Grow in average, dry to medium, well-drained, alkaline soil in full sun. English lavender can be difficult to grow in the St. Louis area, primarily because of winter stresses and high summer humidity. Well-drained soils are required, particularly in winter. Root rot commonly attacks plants grown in poorly drained soils. Prefers a light, sandy soil with somewhat low fertility. Remove faded flowers to promote continued bloom. Prune to shape in spring after new leaves appear. Prune back to 8” in spring every 3 years to control plant size and to promote robust, new growth. High summer humidity in the St. Louis area is not appreciated. To combat high humidity, consider using rock instead of organic mulch. English lavender has slightly better winter hardiness than lavandin (Lavandula x intermedia) for the St. Louis area, but still may appreciate a sheltered location and winter protection.
Lavandula angustifolia, commonly called English lavender, has been a mainstay of herb gardens for many years. Despite its common name, it is not in fact native to England, but comes primarily from the Mediterranean region. It was reportedly named English lavender because of its ability to grow well in the English climate. This “true lavender” is commercially planted for harvesting its oils for use in perfumes. Lavender flowers and foliage are also popular additions to sachets and potpourris. English lavender varieties are more often used for culinary purposes than other types of lavender. This is a semi-woody plant that typically grows to 1.5-3’. Narrow, gray-green leaves (to 2 1/2” long) on square stems. Purple flowers appear in terminal spikes in late spring to early summer. Both foliage and flowers are highly aromatic. Leaves are evergreen in warm winter climates.
Genus name comes from the Latin word lavo meaning I wash in reference to a former use of the plant as an aromatic wash.
Specific epithet means having narrow leaves.
‘Munstead’ is a compact, early-flowering English lavender cultivar that was first introduced into commerce in 1916. It is a semi-woody perennial that typically grows to 12-18” tall and as wide. Lavender blue flowers appear in terminal spikes in late spring well into summer. Munstead’ was reportedly named for Munstead Woods in England where the plant was grown by garden designer Gertrude Jekyll (1843-1932).
Susceptible to leaf spot and root rot. Plants may not survive in winter if soils are not well-drained and/or if temperatures dip below zero degrees without protective snow cover.
This is a versatile garden perennial that should be considered for a wide variety of uses and not just relegated to a corner of the herb garden. Lavender flowers and green-gray leaves provide mid-summer color and contrast to the perennial border front, rock garden, herb garden or scented garden. Can be particularly effective when massed. Also effective as an edger or low hedge in some areas. Fragrant flowers may be dried and used in sachets and potpourris.
