I. The Origins of Grosso Lavender
Grosso lavender, also known as Lavandin Grosso, is a hybrid created by crossing two lavender species: Lavandula angustifolia (English lavender) and Lavandula latifolia (spike lavender). This hybridization results in a plant with the best qualities of both parent species, making Grosso lavender a highly sought-after variety for its vigor, hardiness, and high essential oil content.
II. Characteristics of Grosso Lavender
Grosso lavender is a popular choice for gardeners because of its unique characteristics, including:
- Size: Grosso lavender grows to an average height of 30-36 inches (75-90 cm) and spreads 24-30 inches (60-75 cm) wide, making it one of the larger lavender varieties.
- Flower Color: The plant boasts deep violet-blue flowers on long, sturdy stems, which create a striking contrast against its gray-green foliage.
- Bloom Time: Grosso lavender blooms from late June to early August, depending on the growing zone.
- Fragrance: The plant emits a strong, sweet lavender scent, making it an ideal choice for gardens, borders, and aromatic plantings.
III. Choosing the Perfect Site for Grosso Lavender
To ensure a healthy, flourishing Grosso lavender plant, it is essential to select the right location. Keep the following factors in mind when choosing a spot for your lavender:
- Sunlight: Grosso lavender requires full sun for at least 6-8 hours a day.
- Soil: The plant thrives in well-draining, slightly alkaline soil with a pH of 6.5-7.5. It is also drought-tolerant and prefers less fertile soil.
- Climate: Grosso lavender is hardy in USDA zones 5-9, but it can be grown in cooler climates if given proper winter protection.
IV. Planting and Growing Grosso Lavender
Once you’ve chosen the perfect location, follow these steps for planting and growing Grosso lavender:
- Soil Preparation: Amend the soil with organic matter, such as compost, to improve drainage. If your soil is acidic, add lime to increase the pH.
- Planting: Space Grosso lavender plants 24-30 inches (60-75 cm) apart to ensure proper air circulation. Plant in early spring or fall, depending on your growing zone.
- Watering: Water the plant deeply but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot and other problems.
- Fertilizing: Grosso lavender requires minimal fertilizing. Apply a balanced, slow-release fertilizer in the spring to promote healthy growth. Avoid over-fertilizing, as it can lead to excessive foliage growth and reduced flower production.
V. Harvesting Grosso Lavender
To harvest Grosso lavender for use in various applications, follow these guidelines:
- Timing: Harvest Grosso lavender flowers just as the buds begin to open, typically in the early morning to preserve the essential oil content.
- Cutting: Use sharp, clean pruning shears to cut the flower stems, leaving some foliage on the plant to promote regrowth.
- Drying: Bundle the harvested stems and hang them upside down in a cool, dry, dark location with good air circulation. Allow them to dry for 1-2 weeks.
VI. Pruning and Winter Care
Proper pruning and winter care are essential to maintaining a healthy Grosso lavender plant. Follow these steps:
- Pruning: Prune Grosso lavender plants in late summer after flowering or in early spring before new growth emerges. Remove dead, damaged, or diseased stems, and shape the plant to maintain its compact form.
- Winter Care: In colder climates, protect Grosso lavender plants by applying a layer of mulch around the base, being careful not to cover the crown of the plant. If necessary, provide additional protection with a burlap wrap or frost cloth.
VII. Pests and Diseases
Grosso lavender is generally resistant to pests and diseases, but some problems may arise:
- Pests: Aphids and whiteflies may infest Grosso lavender. Control these pests by applying insecticidal soap or introducing beneficial insects, such as ladybugs.
- Diseases: Root rot, leaf spot, and fungal infections can occur if the plant is overwatered or grown in poorly draining soil. Prevent these issues by providing proper care and ensuring adequate drainage.

Grosso lavender has a myriad of uses and benefits, including:
