- Spacing: Since they’re dwarf, space the plants about 15-20 cm apart.

- Nitrogen Fixation: As legumes, lupins form symbiotic relationships with nitrogen-fixing bacteria in their roots. These bacteria convert atmospheric nitrogen into a form that plants can use, enriching the soil. This makes lupins valuable in crop rotations or as a green manure crop.
- Pollinator Attraction: Lupins are very attractive to pollinators like bees, butterflies, and hummingbirds. The bright colors and abundant nectar make them a favorite in pollinator-friendly gardens.
