SuperBlue Lavender: A Foot-Tall English Lavender in Rich Blue
Save
SuperBlue lavender is small in stature and loud in color. It is a compact English lavender that stays about a foot tall and wide, with green foliage and large, rich blue blooms on short spikes. It also has a long bloom window, documented from spring into September, with a peak in mid-July.
As a Lavandula angustifolia, it is documented for strong winter hardiness and landscape performance. It also does not need a cold spell before it blooms, which helps it flower early in its life.

Where a foot-tall lavender shines
Most lavenders need two or three feet. SuperBlue needs one, which opens up spots other lavenders cannot use: the gap between pavers, the front inch of a raised bed, a window box, the edge of a patio planter or a row along a short walkway. Its blue reads strongly from a distance even though the plant is small, so a line of them has real impact.
It also suits gardeners who want lavender but are short on full-sun ground. A couple of pots on a sunny step will do.
Planting
Choose full sun and very well-drained soil. For edging, space plants about 12 inches apart so they knit into a low border. In containers, use a gritty mix and a pot with a drainage hole; a 10- to 12-inch pot suits one plant.
Small plants dry out faster than big ones, so check plugs and pots more often in their first summer. Water deeply, then let the top of the soil dry before watering again. Once settled in the ground, water needs are low.
Care through the season
- Deadheading: SuperBlue has a high rebloom rating. Snip spent spikes back to the foliage as each flush fades to encourage the next.
- Shaping: a light trim in late summer keeps the mound tight. With a plant this small, use hand pruners or scissors rather than shears.
- Feeding: very little. Extra nitrogen makes soft, floppy growth.
- Winter: in-ground plants are documented as strongly hardy. Potted plants are more exposed, so shelter pots against the house or sink them into the soil over winter.

Using the flowers
The short spikes are not made for long-stemmed bouquets, but they are perfect for small posies, drying for sachets and snipping for the kitchen. English lavender is widely used in cooking and SuperBlue carries a great culinary rating; use buds from plants grown as food and start with a small amount. Its essential oil suitability is rated excellent, and bees rate it highly too.
Choosing a plant size
It is offered as 3-inch plugs, 4-inch pots and 1-gallon pots. A gallon pot gives an instant, full plant for a container. See the product page for current sizes and availability, and use Notify Me there if a size is not ready.
