Tree lupins

RHS Genus Guide
Tree lupins are usually short-lived but fast-growing woody plants with silky-textured, grey-green, usually evergreen leaves and typical lupin flowers. You can combine them with other sun-loving shrubs, such as lavender, rosemary and cistus.

They grow well in gravel gardens and are good for coastal situations where they are able to cope with the salty air and windy conditions .

RHS / Graham Titchmarsh

Appearance

Tree lupins are bushy plants with woody stems topped by spikes of fragrant, creamy-yellow (or sometimes blue or white) flowers in late spring and summer. They usually keep their leaves over winter.

Preferences

These woody lupins are happy in light, sandy soils that drain easily, preferably with slightly acidic conditions. They also like full sun.

Dislikes

They hate heavy, wet soils, and growth may be poor on chalky (alkaline) soils. They do not fare well in shade.
