Growing & using Grosso Lavender

Grosso Lavender in full bloom

Notice the very dusty soil all around the plants. This photo was taken on a day the temperature reached over 100 degrees. And, while these plants receive water every day during a scorcher like that, the ground drains very fast and the oil bakes dry quickly---just the way the lavender likes it.

This Grosso Lavender is about five years old and four feet across with its bloom. It looks a little lopsided because it is watered with an overhead sprinkler that displaces the blooms. A drip system would give a more uniform “ball” look to the plant.

Grosso Lavender is probably the most planted and cultivated lavender in the world. It is used mainly in the production of oil used cosmetically. Planting close together makes a nice hedge and can be good for commercial crops where land is valuable, but blooms will be sacrificed as it crowds up against its neighbor.

See how long the stems are!

This view from above shows just how long the flower wands get. The plant is way down there.

The flower stems of Grossso Lavender are a bright green but the plant is gray which makes the effect of the whole plant even more stunning. It is very important to prune either after bloom in late summer or very early in spring just as the plants starts to perk up. If your late summer is very hot, put off pruning until the weather cools off to about 80. Lavender leaves release oils on hot days which cool the plant off. This is especially important for plants grown with minimal water. Cutting too many of its leaves off stresses the plant under this situation. Spring pruning should be avoided because the plant is setting blooms.

Grosso Lavender with Rosemary and Lavender Vera

In another spot this Grosso Lavender sets off a Rosemary Hedge. Notice the small light flowered Lavender in front. This is Lavender Vera, one of the most highly prized medicinal Lavenders. Just next to the Lavender Vera are some dried Yellow Lavender flower heads. These will be saved and collected for seed.

Grosso Lavender and butterfly

Lavender is very important for pollinators. It is a nectar source for butterflies and honeybees. Many other beneficial insects also benefit from lavender blooms.

All of our Mother plants start life as one of our three- inch ready-to-go pots. Grosso Lavenders should be planted three feet apart. Even here where summers can be brutally hot, they can be planted in the full sun. Be sure to provide adequate moisture for a splendid show!
