Lavandula
Fragrant, Drought-Tolerant, Pollinator-Friendly
- Unmistakable Fragrance: Lavender is cherished for its iconic, calming fragrance, used in aromatherapy, perfumes, soaps, and potpourri.
- Beautiful Flowers: Lavender produces spikes of beautiful flowers in shades of purple, blue, pink, or white, depending on the variety.
- Attracts Pollinators: Bees, butterflies, and other beneficial insects are drawn to Lavender's nectar-rich flowers.
- Drought-Tolerant & Low-Maintenance: Once established, Lavender is exceptionally drought-tolerant and requires minimal care. It thrives in hot, sunny, and dry conditions.
- Deer and Rabbit Resistant: The strong scent of Lavender deters deer and rabbits.
- Versatile Uses:
- Ornamental Gardens (borders, hedges, rock gardens)
- Herb Gardens
- Containers and Pots
- Cut Flowers (fresh or dried)
- Culinary Uses (in moderation)
- Craft Projects (sachets, wands)
- Medicinal properties: Often used in aromatherapy for relaxation and sleep.
Key Differences:
- Lavandula angustifolia (English Lavender): Generally, the most cold-hardy and has the classic, sweet lavender fragrance. Many popular cultivars like 'Hidcote' and 'Munstead' belong to this species.
- Lavandula x intermedia (Lavandin): A hybrid between L. angustifolia and L. latifolia. Typically, larger plants with a stronger, more camphoraceous scent. Often used for essential oil production. 'Grosso' is a well-known Lavandin.
- Lavandula stoechas (Spanish or French Lavender): Distinguished by its "ears" or bracts on top of the flower spikes. Less cold-hardy than English Lavender. Prefers milder climates.
- Lavandula dentata (Fringed Lavender): Has toothed leaves and a slightly different scent. Also, less cold-hardy.
Light: Full sun (at least 6-8 hours of direct sunlight per day) is essential for best growth and flowering.
Soil: Well-drained soil is critical. Lavender hates wet feet and is prone to root rot in soggy soil. Sandy or gravelly soil is ideal. Amend heavy clay soils extensively with compost, grit, or sand to improve drainage. A slightly alkaline to neutral pH (6.5-8.0) is preferred.
Water: Water regularly during the first growing season to establish a deep root system. Once established, Lavender is very drought-tolerant. Water deeply but infrequently, allowing the soil to dry out completely between waterings. Overwatering is a common cause of Lavender failure.
Planting (Potted Plants):
- When: Spring or early fall.
- How:
- Dig a hole slightly larger than the root ball.
- Gently loosen any circling roots.
- Place the plant so the top of the root ball is level with the soil surface.
- Backfill, firm gently, and water thoroughly.
- Spacing: Space plants 12-36 inches apart, depending on the cultivar and intended use (closer for hedges, further apart for specimen plants).
Planting (Bare-Root Plants):
- When: Early spring, as soon as the soil can be worked, is ideal. Fall planting is also possible in milder climates.
- How:
- Soak: Before planting, soak the bare roots in water for 1-2 hours (but no longer than 4 hours). This rehydrates the roots.
- Prepare the Hole: Dig a hole wide enough to accommodate the spread-out roots and deep enough so that the crown of the plant (where the roots meet the stem) will be at or slightly above the soil level. Do not bury the crown too deep.
- Spread the Roots: Gently spread the roots out in the hole.
- Backfill: Backfill with the amended soil, firming gently to eliminate air pockets.
- Water Thoroughly: Water deeply after planting to settle the soil and help the roots establish.
- Mulch is not always recommended, but if using mulch, use an inorganic mulch like pebbles or gravel.
Fertilizing: Lavender generally does not need much fertilizer. In fact, over-fertilizing can lead to lush foliage but fewer flowers and a weaker scent. A light application of compost or a low-nitrogen, slow-release fertilizer in early spring is usually sufficient, especially in poor soils.
Pruning:
- Annual Pruning: Prune Lavender annually in late summer or early fall after flowering (or in early spring in colder climates where fall pruning is risky).
- Cut back the flower stalks and about 1/3 of the current year's growth.
- Do not cut into old, bare wood (wood without any green growth), as Lavender often does not regenerate from old wood.
- Shape the plant into a rounded mound.
- Deadheading: Remove spent flower stalks throughout the blooming season to encourage more blooms.
Propagation:
- Lavender can be propagated from softwood cuttings taken in spring or summer.
- Seed propagation is possible, but cultivars may not come true from seed.
Winter Care:
- In colder climates (zones 5 and below), Lavender may need winter protection, such as a layer of mulch (applied after the ground freezes) or a burlap wrap. Good drainage is essential for winter survival.
- In milder climates, Lavender is generally evergreen.
Pests and Diseases:
- Generally, pest and disease-free when grown in well-drained soil and full sun. Root rot is the most common problem, caused by overwatering or poor drainage.
- Spider mites and aphids can occasionally be a problem but are usually not serious.
Container Growing: Lavender grows well in containers. Use a well-draining potting mix and a pot with drainage holes. Terra cotta pots are a good choice because they allow for better air circulation. Container-grown plants may need more frequent watering than those in the ground.
