Purple Treasure Lavender: Tidy Blue-Violet Color Since 2016
Save
Purple Treasure lavender is a newer English lavender, introduced in 2016, bred for a tidy, compact, well-branched shape. Its spikes run from bright blue-purple to a deep, dark blue-purple, and they sit over gray-green foliage that stays neat without a lot of fuss.
If you have been burned by lavender that sprawls open in the middle by year three, this is the kind of plant that keeps its posture.

Why a compact English lavender earns its spot
Compact lavenders solve a few common problems at once. They fit along paths and patios without swallowing the walkway, they look full in a container, and their dense branching means more flowering stems per plant. Purple Treasure's even two-by-two-foot footprint makes it easy to plan: a row of them reads as a single, low lavender ribbon.
The blue-leaning flowers are useful for color design too. Next to a pink or white lavender, Purple Treasure provides the deep anchor color; next to silver foliage plants, the blue tone looks especially rich.
Planting it right
Choose full sun, at least six to eight hours a day, and soil that never stays soggy. If your ground is heavy, build a raised row or plant on a low mound so water runs away from the crown. Space plants about 24 inches apart, set them at the same depth they grew in the pot and water deeply after planting.
For containers, a pot 12 inches or wider with a gritty mix works well. Container plants dry out faster, so check them more often than in-ground plants, but still let the mix dry between waterings.
Pruning and seasonal care
- After the main bloom: cut stems back and shape the mound into a soft dome, leaving some green leaves on every branch.
- Late summer: a light second trim after any rebloom keeps it tidy going into fall.
- Fertilizer: rarely needed. Rich soil makes soft growth that flops.
- Winter: no heavy mulch over the crown; drainage is the real insurance.
The Pruning Calendar lays out the timing month by month.
From garden to kitchen
Purple Treasure is rated great for culinary use, with the sweet, low-camphor flavor English lavender is known for. Its 12-inch stems are long enough to bundle and dry. Harvest on a dry morning when buds are colored but mostly unopened, hang small bunches in the shade, then strip the buds for baking or lavender sugar. Use food-grown buds only, and start small.
