Lupinus spp.
Hardy perennial with tall flower spikes that suits borders in most parts of the UK. Give it full sun and well-drained soil, and avoid heavy, waterlogged ground.
Step-by-step instructions for growing Lupin
Plant into prepared soil around 26th February - 12th April, setting the crown at the same level it was growing before. Water in thoroughly straight away, then keep the soil just moist while the roots settle.
From 20th March, water newly planted lupins during dry spells in their first season. Aim for a deep soak rather than frequent light watering, and avoid leaving the soil sodden.
Remove faded flower spikes from 27th May to keep the display going and stop the plant putting energy into seed. If you leave some spikes to ripen, collect seed from the most reliable plants only.
After the main flowering flush, cut spent stems down to a tidy framework from 11th July. Leave healthy new basal growth in place, because that keeps the plant strong for next year.
From 22nd September, remove any dead foliage and clear away fallen debris around the crown. Leave the crown intact and do not cut hard into the base, as established plants need that growing point protected.
Tap a plant to see why it works (or doesn't) with Lupin.
Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
