Hyssop

Hyssopus officinalisLamiaceaeSubshrub

An old monastery-garden herb that has been grown deliberately near beehives for centuries, and one of the most nectar-productive small plants in a dry sunny border. Hyssop flowers in narrow deep blue spikes through high summer, tolerates drought entirely, and secretes freely in the heat that shuts many border plants down.

Value to bees

Nectar
Very high
Pollen
Moderate
As a honey crop
Minor honey crop — a surplus only locally or occasionally
Which bees, and why
Worked constantly by honey bees and bumblebees. Its long association with monastic beekeeping is not accidental — it was planted beside hives precisely because it produces so freely for its size.

Short two-lipped flowers with accessible nectar and protruding stamens, usable by short-tongued bees.

Worth knowing
Very high nectar per square metre from a small drought-proof plant, delivered across the late-summer gap.

Flowering

In flower
June to September (northern hemisphere)

A long window through high summer, extendable by cutting back after the first flush.

When nectar flows
Exceptionally productive for the size of the plant, and it keeps secreting through hot dry spells.
Year-to-year variation
Very dependable. A honey crop only where it is grown at field scale, which is rare.

Growing it

Conditions
Full sun, poor sharply drained alkaline soil. It dies of winter wet, not of cold.
Size
40-60 cm.
Native range
Southern Europe and the Middle East.
Suits
Containers and window boxes, Small gardens, Large gardens, Hedgerow
  • Cut back by a third after the first flush for a second flowering into September.
  • Trim lightly in spring to keep it dense; it becomes leggy and woody if left entirely alone.
  • Excellent as a low informal edging in a dry border, and a genuinely serious bee plant for the space it takes.

What it looks like

A neat semi-evergreen subshrub with narrow aromatic leaves and slender one-sided spikes of small deep violet-blue two-lipped flowers with protruding stamens.
