About Garden lupin
Lupinus nootkatensis × polyphyllus, a lupine hybrid, is a vigorous perennial plant renowned for its striking flower spikes that emerge in summer. Its dense inflorescences, often in vibrant shades of blue, purple, pink, or white, bring a spectacular touch to any garden. It is ideal for flower beds, borders, or as a focal plant in cottage or naturalistic garden styles.

Care tips
It prefers full sun for optimal flowering, though it tolerates some partial shade in hot climates. Watering should be regular, especially during dry periods and the flowering stage, but avoid waterlogging as it does not tolerate excessively wet soils. It requires well-drained, slightly acidic to neutral soil. A common mistake is planting it in heavy, clay soils, which can lead to root rot.
