Lupinus or lupine is a perennial herbaceous plant native to North America. It consists of basal rosettes consisting of rounded, palmate leaves, composed of 10-15 lance-shaped, elongated gray-green leaves, with a slightly velvety underside, carried by a long petiole, forming a bush 40-50 cm high; in June-July it produces long erect spikes, consisting of numerous brightly colored flowers, generally blue or purple, but there are cultivars of various colors, from white to red; often the flowers are two-colored, they have a shape similar to pea flowers; during flowering the plants reach 110-120 cm in height. The flowers are followed by fruits, oblong pods, containing some seeds. These plants have a fairly slow development, and sometimes bloom only from the second year after planting.

Lupine plants in general can withstand short periods of drought, but develop in a richer and more balanced way if they are watered regularly, from March to September, avoiding however to soak the soil too much and with the foresight to check that there is not the formation of water stagnation that could compromise the health of the plant.From March to July it is good to supply the plant with specific fertilizer for flowering plants, mixed with the water of the watering, every 10-15 days so that the flowering can be luxuriant and abundant.Ground

For the best growth of lupinus plants it is good to use a good rich, loose and well-drained soil, consisting of balanced soil mixed with sand and pumice stone. Wanting these plants can also be grown in a container, remembering to guarantee a good amount of soil by planting them in a large vase. Check that in the container there is not the possibility of the formation of water stagnations that are harmful to the lupine specimens.


The multiplication of these plants turns out to be easy to implement and, generally, occurs by seed, at the beginning of the spring season; It is also possible to propagate the lupins by dividing the clumps chosen among those with well-developed leaves, taking care to maintain a vigorous root for each portion practiced to be placed directly at home.
