Description
The Yellow Lupine is a specialist for acidic, light sandy soils and drives its strong taproot deep into the substrate. Through its nitrogen-fixing actinobacteria it fixes large amounts of atmospheric nitrogen and also captures otherwise unavailable phosphate with its roots. Its yellow, fragrant flower spikes are also a valuable forage for bees.
Care instructions
Sow the Yellow Lupine from April to June (weeks 14–26) on acidic to neutral, low-calcium soils – it does not thrive on calcareous soils. Plant the seeds about three centimeters deep. Cut back or mow the stand at flowering (July, week 28) and work it in flat before the stems harden.
