Keep moist during germination. Water when they look a bit droopy.
Lupins may need staking although more modern varieties are more dwarf in character.
Remove old flower spikes as the flowers fade to conserve the plant’s energy and encourage further blooms
Lupins can also be grown by careful division of mature plants in the spring or by basal cuttings in the spring taken with a small portion of root tissue, strike into vermiculite to reduce the risk of rot.
Plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Lupin is thought of as hardy, so this plant will survive close to or on freezing temperatures.
See our list of companion Plants for Lupin to see which plants you should plant in close proximity to encourage growth.
Cover lightly and press down to ensure good contact with soil. Sow seeds in autumn and winter (frost free areas), or late summer and autumn in areas prone to frost. Sow directly into flower beds.
Alternatively, soak the seeds for 24 hours in water and sow into pots or modules in spring , summer or autumn, growing on in sheltered conditions
Thin out at 5cm (2") height to 30×30 cm apart.
When pot grown seedlings are large enough plant out in late summer or after over wintering under protection in the spring after all danger of frost has past.
Lupins require a bright sunny spot in the centre to the back of the border in well drained slightly acidic soil conditionsAs Lupin is hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
Lupins are used as cut flowers and are best picked when the bottom third of the flower spike has opened
Some lupins are used as green manure as bacteria in the root nodules can fix nitrogen from the atmosphere.
They can also be used as animal feed an lupin flour is used in food production, however care must be taken lupins can also contain toxins
Allow a few seeds to grow to maturity on the flower spike and harvest as the pod turns brown dry and crispy. Collect into a paper bag and continue to dry on a warm windowsill until the pod twists open to release the seeds
Seeds store well and are long lived, but may not show characteristics of the parent plant if openly pollenated.
