Bramble
The most valuable bee plant nobody plants. Bramble flowers for three months through high summer, produces nectar reliably in a wide range of weather, and is worked by an enormous range of insects. In much of northern Europe it is the single largest contributor to summer honey, and it grows on waste ground, in hedges and along railway lines without anyone's help.
Where not to plant it
Seriously invasive outside its native range, particularly in Australia, New Zealand, the Pacific North-West of North America and parts of South America, where it forms impenetrable thickets and displaces native vegetation. Do not plant it in those regions — the fact that it is superb bee forage in Europe does not transfer.
Caution
Thorny and vigorous. It will take over ground if left entirely alone.
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
- Open accessible flowers worked by essentially every flower-visiting insect in the landscape. A bramble patch in July is the easiest place to see the full range of local bee diversity in one spot.
- Worth knowing
- The combination of a very long season, high nectar value and reliability in variable weather makes bramble the workhorse of northern European summer forage.
Flowering
- In flower
- June to September (northern hemisphere)
An unusually long flowering period, because different microspecies and different canes come into flower at different times.
- When nectar flows
- Steady and dependable through the summer — one of the most reliable nectar sources in the temperate flora, which is precisely what makes it so valuable.
What it does to the honey
Contributes a fruity, medium-amber character with a soft acidity to summer wildflower honey. Bramble-dominated honey is one of the most pleasant multiflorals in northern Europe.
Growing it
- Conditions
- Sun or partial shade, tolerant of almost any soil, thrives on neglect.
- Size
- Scrambling to 3 m or more, spreading indefinitely by rooting cane tips.
- Native range
- Europe and western Asia; naturalised and invasive in many parts of the world.
- Suits
- Hedgerow, Large gardens, Meadow or wildflower area
- Rarely needs planting — it arrives. The useful decision is whether to leave a patch rather than whether to establish one.
- Cultivated thornless blackberry varieties are also good forage and far easier to manage in a garden.
- Canes fruit in their second year, so cutting everything to the ground annually removes both flowers and fruit.
What it looks like
A scrambling thorny shrub with arching biennial canes, compound leaves and clusters of white or pink five-petalled flowers, followed by blackberries. An aggregate of hundreds of microspecies that are difficult to tell apart and are usually treated together.

Guides covering this plant
- How bees collect and process nectarA forager carries nectar in a stomach she does not digest from, hands it to a receiver who begins altering it chemically, and the colony then removes most of its water. The honey is made by the hive, not by the forager.
- The best plants for beesA shortlist chosen on three criteria: how much nectar and pollen the plant produces, how accessible it is to different bees, and when it flowers. Season coverage matters more than any individual plant.
- Bee plants through the yearThe gaps matter more than the peaks. Almost every garden has plenty in June and nothing in February, and it is the empty months that limit what a garden can support.
- Summer plants for beesSummer looks abundant and contains a real gap. The weeks between the spring blossom finishing and high summer starting are thinner than most gardens realise, and colonies are at peak population when it happens.
- A bee-friendly garden in Britain and IrelandAround 270 bee species, one honey bee among them, and a climate that gives you flowering months at both ends of the year that most of the world does not get. The British gaps are February and late June, and both are fixable.
- Visiting a flower is not the same as pollinating itA bee on a flower may be pollinating it, robbing it, or doing nothing for it at all. The distinction is why 'attracts bees' on a plant label tells you almost nothing, and why visit counts are a poor measure of pollination.
- Nesting habitat: the half of bee gardening that is not flowersAround seventy per cent of bee species nest in bare ground and most of the rest in stems, wood or cavities. A garden can be full of flowers and offer nowhere at all to live.
