Heather

Calluna vulgarisEricaceaeSubshrub

The plant that turns British and northern European moorland purple in August, and the source of one of the world's most unusual honeys. Heather flowers at the very end of the northern summer, on acid ground that supports almost nothing else, and its nectar produces a thixotropic honey that behaves like no other. Whole beekeeping traditions in Scotland, northern England and the German heaths exist to catch this one flow.

Value to bees

Nectar
Very high
Pollen
High
As a honey crop
Major honey crop — yields a surplus in good years
Which bees, and why
Heavily worked in the short window, by honey bees moved onto the moors and by a distinctive community of heathland bumblebees and solitary bees that depend on it.

Flowering

Typically in flower
August to September (northern hemisphere)

Bell heather (Erica cinerea) flowers earlier, from June, and cross-leaved heath from July, so a mixed moor offers a longer season than ling alone.

A typical window for the species, HoneyHQ synthesis — it moves with latitude, altitude and the year.

When nectar flows
Requires warmth and humidity together. A cold or dry August produces very little, and heather crops fail entirely in some years — which is the accepted risk of moving hives to the moors.
Year-to-year variation
Among the most weather-dependent honey crops anywhere. Beekeepers describe heather as either the best year they have had or nothing at all.

Sourced periods for this plant

Read from a source for the place named, and kept apart from the typical windows elsewhere on HoneyHQ, which are synthesis. Flowering, nectar flow and harvest are different periods.

  • Flowering: Heather — September–October

    Provence (the PGI area), France · northern hemisphere · Months as stated · Protected-name specification

    "Late flowerings — September–October for heather, for example" (HoneyHQ's translation from the French of the specification). The specification names tree heath, ling and bell heather among Provence's heathers.

    Heather honeys are harvested in the Maures, the Estérel and the Var coast.

What it does to the honey

Produces the smoky, slightly bitter, jelly-textured heather honey — the thixotropic gel is a protein-driven property of this nectar specifically, and it is why the honey must be pressed rather than spun.

Growing it

Conditions
Full sun and acid, free-draining, poor soil. It will not grow on chalk or limestone at all.
Size
20-60 cm, spreading to form continuous carpets.
Native range
Europe and Asia Minor, dominant on acid heath, moorland and bog margins; naturalised in North America and New Zealand.
Suits
Small gardens, Large gardens, Containers and window boxes
Maintenance, and the bit that matters
Moorland heather is managed by rotational burning and grazing for grouse and sheep. The effect on bee forage depends entirely on rotation length — a burn cycle that keeps heather young keeps it flowering, and one that does not, does not.
  • Needs genuinely acid soil — ericaceous compost in a container if the garden is alkaline.
  • Winter-flowering heaths (Erica carnea) tolerate slightly alkaline soil and, more usefully, flower from December to April, providing forage in the leanest months.
  • Trim lightly after flowering to keep plants dense.

What it looks like

A low evergreen subshrub with tiny scale-like leaves packed along wiry stems, carrying dense spikes of small bell-shaped flowers in purple-pink, occasionally white.
