Lavandula × intermedia 'Grosso'

lavender

Product Image
This vigorous English lavender produces masses of slender spikes of vivid violet flowers between July and August, above grey-green leaves.

Lavandula × intermedia 'Grosso' makes a gorgeous, flowering, informal hedge, especially along a path, where its fragrance can be appreciated. It works well in a Mediterranean garden, or clipped into a formal sphere for a contemporary look.

The flower-spikes are also a magnet for bees and other nectar-loving insects.

How to care for Lavandula × intermedia Grosso:

Plant in a sunny, well-drained spot with slightly alkaline soil. This lavender becomes drought-tolerant once established, making it an excellent choice for low-maintenance gardens or containers.

Water the plant deeply but sparingly, as overwatering can lead to root rot. In colder climates, consider providing some winter protection by mulching around the base, especially during its first year.

In early spring, typically in April, carefully trim the plant to remove any damaged or dead growth. After the flowers have faded, trim the flower stalks to maintain the plant’s neat shape, but be cautious not to cut into the thicker, woody stems, as lavender doesn't regenerate well from old wood.
