Many insects are still out foraging in late-summer, it’s a good idea to provide food for them with nectar-rich, late-flowering plants.
While some plants have finished flowering, bees, butterflies and hoverflies are still on the wing, foraging for food. Nectar provides insects with energy to fly and builds them up for winter hibernation. By growing just one source of nectar-rich food, you can improve these insects’ chances of surviving the cold months.
Insects you’ll attract to your garden include buff-tailed and common carder bumblebees, honeybees, hoverflies, comma, painted lady, small tortoisehell, speckled wood butterflies and the angel shades, dart and brimstone moths. Some will still be found foraging on flowers in November, while – in the south of the UK – some buff-tailed bumblebee colonies will remain on the wing throughout winter.
We pick some of the best plants to grow that will provide pollinators with a source of late nectar.

This climbing evergreen provides a supply of nectar and pollen until late November. Holly blue caterpillars also feed on ivy leaves, while many other insects hibernate in its foliage.

Late-flowering buddleja supplies insects with nectar when others have finished flowering. Pollinators attracted to its blooms include bees, moths and hoverflies.

Many hebe cultivars flower from late summer to autumn, attracting bumblebees, honeybees, butterflies, moths and hoverflies.

Hylotelephium spectabile is a trusty, late-flowering favourite. The plant’s pink flowers make the perfect landing pad for pollinators such as butterflies, moths, bumblebees and honeybees.

Rather than clearing your borders in autumn, leave the plants standing so insects and other wildlife can take shelter until spring. Birds will also strip seedheads – often in large flocks – giving you a wonderful show.
