Lupin Overview

The garden lupin is used in gardens for its attractive flowers, attracting bees and the nitrogen fixing ability of the plant. It can improve poor soils. Naturally, it grows along streams and creeks, preferring moist habitats. Lupins grown in gardens today are hybrids of crossing L. polyphyllus with L. arboreus, L. sulphureus and one or more annual species. The crossing resulted in plants with flower spikes that were denser, larger, and more colourful than the originals. These hybrids are known as Russel hybrids, named after the horticulturist who bred them.

Common problems with Lupin

Generally problem free, but aphids can be a problem. Encourage beneficial insects like lady bugs or spray with organic insecticide when beneficial insects are not around.

How to propagate Lupin


Sow seeds in autumn in damp soil or cold treated seeds in spring. To cold treat place seeds in a ziplock bag with slightly damp towel into a refrigerator for 7 days.


Cut a small stem down to trunk, including a bit of its connection to the trunk, set in moist, very well-drained, propagation medium. Keep covered opening a few minutes daily for airflow.
