Description
It grows quite large, reaching up to 1.5 m in height, with a bushy habit and upright stems. Its decoration is both its grey-green, palmate leaves and its numerous flowers in all the colours of the rainbow, gathered in majestic, spire-like spikes. The fruit is a broad, hairy pod containing 5 to 12 seeds.
Requirements
It likes sunny places and sandy, humus-rich soils that are dry or moderately moist. It does not tolerate a lot of lime in the soil.
Propagation
Lupins are propagated from seed (collected in autumn) sown in spring. The seeds ripen in the first half of August. It is recommended to soak them for several hours before sowing, which greatly speeds up germination.
Care
After flowering, if you do not need the seeds, cut the plant back to encourage it to flower again in autumn. Do not remove all the leaves when cutting – leave the youngest ones.
