About Blue lupin
Lupinus cosentinii, commonly known as Cosentini's lupin, is an annual legume native to the Mediterranean region, valued for its spikes of blue or purple flowers. With an upright habit and grayish-green foliage, it adds a wild and colorful touch to low-maintenance gardens, rockeries, or as a groundcover. It is particularly beneficial for soil improvement due to its nitrogen-fixing capabilities.

Care tips
It prefers full sun exposure for abundant flowering and vigorous growth. It requires moderate watering, allowing the top layer of the substrate to dry out slightly between waterings, and is quite drought-tolerant once established. It thrives in well-drained soils, even poor or sandy ones, avoiding waterlogging at all costs. A common mistake is overwatering, which can lead to root rot.
