Grey Hedge Lavender: A Silver Lavandin Built for Rows
Save
Grey Hedge lavender is a lavandin with silver-gray foliage and a bushy, mounding habit about 30 inches tall and 3 feet wide. Purple flowers arrive in mid-July in one strong flush, carrying the strong floral-herbal scent of lavandin, sweet lavender with a fresh camphor note.
The name tells you its best use. A line of these mounds makes a soft, silver hedge that looks tidy all season and turns purple and fragrant in July.

Planning a lavender hedge
A lavender hedge is not a privacy wall; it is a low, fragrant edge for a path, a patio, a vegetable garden or a driveway. At about 30 inches, Grey Hedge sits at a comfortable height to define a space without blocking views.
- Spacing: 24 to 30 inches apart for plants that grow together; 36 inches for a scalloped row of separate mounds.
- Setback: plant the row at least 18 inches back from a walkway so mature plants do not crowd it.
- Layout: run a string line and plant in a straight row. Small differences in spacing show up in a hedge.
- Quantity: divide the hedge length by your spacing and add one.
The My Garden planner can help you sketch the row.
Soil and planting
A hedge is only as strong as its weakest plant, and wet spots are what create gaps. Choose full sun and well-drained soil along the whole run. If part of the line sits low or holds water, raise that stretch with a berm. Set each crown at soil level and water the row deeply at planting and through the first season.
Grey Hedge needs a winter chill to flower well. As a hybrid, its cultivar-specific hardiness rating, zones 5a to 8b, is the one to plan around.
Shearing for an even line
After the July bloom, cut the flower stems and shear the whole row in one pass, shaping each plant into a rounded top. Leave a few inches of green above the woody base. Finish by early fall. In spring, tidy any winter tips once growth starts. An annual shear is what keeps a lavandin hedge dense instead of splitting open with age. See the Pruning Calendar.
Harvest from the hedge
A hedge doubles as a harvest row. Grey Hedge rates excellent for fresh bouquets, dried flowers and oil. Cut stems for drying as the first flowers open and hang them in a dark, airy place. Lavandin rates good for culinary use but carries more camphor than English lavender, so use it lightly in food.
Plant sizes
Offered as 3-inch plugs, 4-inch pots and 1-gallon pots. Plugs keep a long hedge affordable; gallons fill in faster. See the product page for current sizes and availability.
Frequently asked questions
How long until the hedge fills in?
It depends on spacing and plant size. Closer spacing and larger starting plants close gaps sooner.
Does it rebloom?
Rebloom is low. Expect one main flush in mid-July.
Will deer browse it?
It is rated deer resistant, which makes it a dependable boundary planting.
