Lavandin (L. angustifolia x L. latifolia) is a popular hybrid lavender for the herb garden. Although it is rarely used for culinary purposes, it is frequently used as an addition to sachets and potpourris. It is a semi-woody plant that typically grows in a shrubby mound to 2-4 tall. Gray-green leaves (to 2 1/2î long and 1/4î wide) appear on square stems. Flowers appear in terminal spikes (to 4î long) in summer. Both foliage and flowers are highly aromatic. Leaves are evergreen in warm winter climates. Hybrid cultivars vary somewhat in habit, flower color, aromatic intensity and bloom time. ... more »

Easily grown in average, dry to medium, well-drained soil in full sun. Lavandin can be difficult to grow in the St. Louis area, primarily because of winter stresses and high summer humidity. Well-drained soils are a must, particularly in winter. Root rot commonly attacks plants grown in poorly-drained soils. Plants prefer a light, sandy, alkaline soil with somewhat low fertility. Remove faded flowers to promote continued bloom. Prune to shape in spring after new leaves appears. Prune back to 8î in spring every 3 years to control plant size and to promote robust, new growth. To combat high humidity, consider using rock instead of organic mulch. Plants are not reliably winter hardy in northern areas of USDA Zone 5 where they appreciate sheltered locations and winter protection.
