Gardeners' Notes:

Neutral saya On Jun 2, 2009, saya from Heerlen
Netherlands (Zone 8b) wrote:

Most of the lavendin that is grown for oil in France is
from this cultivar. Very floriferous on particularly long
stems, forming an arc of colour. Its long stems make it also easier for harvesting. Introduced in 1972 by Pierre
Grosso who grows lavendin commercially for oil production in France.

Beautiful and fragrant Lavender! A joy to grow and smell! Have had 'Grosso; for years and I love it! Looks great in a mixed flowerbed as I have shown in my photos. Sometimes I cut the flowers while still in bloom and they look beautiful added to bouquets! A winner of a Lavender!

This is my favorite Lavendar. I grow four or five types of Lavendar and this is my favorite just for ease of care and fast growth. Extremely drought tolerant, and of course the deer leave them alone!

What a lovely plant.... a beautiful well formed lavender with masses of dense purple lilac flowerheads..... very nice..... Very big lavender on steroids! The more the better! Easy to grow.... mine is in semi acidic soil and thriving.... we also had a somewhat hard winter this year and the plant made it through with flying colors staying evergreen most of the winter.... if you're a lavender lover?.... highly recommended..... :)

When I first bought some, I had to do some additional shopping, so they stood in the back of my van during the trip. Talk about natural fragrancer--my van smelled so good, I was tempted to just leave them there for another couple days. However, reality took over, and it went into the ground, instead. The Grosso lavender has got to be one of the most beautiful lavender plants around!! Its blue-green leaves almost look surreal against our mulched front yard, and the fragrance that emanates from the blossoms are awesome. I can't wait to dry them and make sachet pillows from them...

A sterile hybrid, so a very extended bloom period. This variety's flower stalks are rounder than most, so another common name for this is 'Fat Spike'. Outstanding scent that persists when dried.
