Lupinus densiflorus aureus
Very attractive yellow flowering annual species. Nice for cutting too lasting a few days. Plants grow 1.5 to 2 feet tall and 2 feet wide. Best in full sun and alkaline soils.
Annuals. Native from South Western USA. Soak seeds in warm water for 24 hours, change the water after 12 hours with fresh water. Lightly cover seeds and keep at F 65, germination in 2-15 days. Might be best to sow in place of growth, as most lupines do not like root disturbance.
