Grosso French Lavender (Lavandula x intermedia 'Grosso')

Grosso French Lavender, Lavandula x intermedia 'Grosso', is a vigorous French hybrid lavender valued for its long, arching flower stems, deep violet purple blooms, and intensely fragrant gray green foliage. Plants form a broad, mounded shrub that looks handsome even out of bloom, then send up tall flower wands in summer that sway in the breeze and fill the air with classic lavender perfume. With its strong presence, heavy flower production, and reliable performance in hot, sunny sites, Grosso French Lavender makes an excellent focal point, low hedge, or cutting garden workhorse in herb, cottage, and Mediterranean style plantings.

Distinctive Features

Grosso French Lavender typically grows about 24 to 30 inches tall and 24 to 36 inches wide, with a rounded, shrub like habit and a framework of woody stems at the base. Long, sturdy flower stalks rise well above the foliage and carry dense spikes of violet purple florets, giving a big, showy display when plants are in full bloom. Narrow, gray green leaves add fine texture and a silvery cast that blends easily with stone, gravel, and a wide range of flowering companions. Known for its strong fragrance and long stems, Grosso is a favorite for cut and dried flowers, sachets, and craft work as well as for bold garden color.

Growing Conditions

• Light: Prefers full sun with at least 6 hours of direct light daily for best flowering, strong fragrance, and a compact, sturdy habit.
• Soil: Thrives in well drained, lean to average soils; avoid heavy, wet ground and favor sandy or gravelly conditions that keep roots on the dry side.
• Water: Water regularly after planting to establish; once rooted in, water deeply but infrequently, allowing the top of the soil to dry between waterings.
• Hardiness: Well suited to many temperate regions where French hybrid lavenders are grown outdoors, especially when provided with sharp drainage in winter.
• Size: Generally forms a mound about 24 to 30 inches tall and 24 to 36 inches wide at maturity, depending on climate and care.
• Growth Rate: Moderate grower that fills in steadily and develops a substantial presence without quickly outgrowing beds or large containers.

Ideal Uses

• Bold Focal Point: Use as a single specimen or small group in sunny borders and herb gardens where its tall flower wands and strong scent create a natural focal point.
• Edging and Low Hedges: Plant in a row along paths, drives, or terrace edges to form a low, fragrant hedge of gray green foliage and purple bloom.
• Containers and Patio Pots: Well suited to large pots and tubs where the mounded form and tall flower spikes add height, scent, and movement.
• Herb and Cutting Gardens: Ideal in areas dedicated to herbs and cut flowers where you can harvest stems for fresh or dried use.
• Cottage and Mediterranean Gardens: Mix with roses, salvias, ornamental grasses, and other sun lovers for relaxed cottage combinations or set into gravel for a dry, Mediterranean look.

Low Maintenance Care

• Watering: After establishment, water when the top inch of soil is dry; avoid constant moisture or soggy conditions that can lead to root and crown problems.
• Pruning: Shear lightly after the main flush of bloom to remove spent spikes and shape the mound; avoid cutting back into old, bare wood below the leafy growth.
• Fertilizing: Requires only light feeding; in spring, apply a small amount of balanced, slow release fertilizer if soil is very lean, since excessive nutrients can cause soft, floppy growth.
• Mulching: Use a thin layer of gravel or coarse mulch around the base to improve drainage and keep foliage off wet soil, avoiding heavy organic mulches against the stems.
• Seasonal Care: In colder climates, provide excellent drainage and a sunny, sheltered spot; in late winter or early spring, tidy lightly to remove any winter damage and keep the plant compact and productive.
