Lavandula x intermedia 'Grosso' (25) plants
Common name: English Lavender.
Zones 5 to 9.
Full sun; to flower, Lavender must be grown in full sun.
Plants reach 24 to 30 inches tall and 18 to 24 inches wide.
Growth rate: Moderate, erect herbaceous clump-forming perennial.
Plump, violet-blue flower spikes fill the air with their sweet fragrance from late summer into early fall.
L. intermedia tends to bloom a bit later in the summer with a possible repeat bloom towards fall. 'Grosso' is a cross between L. angustifolia and L. latifolia and is a larger plant overall than these species. These hybrids were first developed in France for use in perfumes and essential oils. Its long flower stems make this variety especially good for use in bouquets.
Lavender will grow in average, dry to medium, well-drained soil; and prefers alkaline, sandy soil with low fertility. To prevent crown rot, well-drained soils are required, particularly in winter, so plant in hot, dry, sunny areas where nothing else seems to grow. Other than that, Lavender is known to have few problems with pests and diseases. Shearing back the evergreen foliage in early spring will rejuvenate plants and stimulate new growth.
Attributes: border plant, in containers, cut and dried flowers and foliage, drought tolerant, evergreen, fragrant, and mass plantings. Attracts butterflies. Deer and rabbit resistant. |
