Dioonid

Dioonid, also known as Dioon, are a genus of flowering plants in the family Asparagaceae, subfamily Agavoideae. They are native to the Mediterranean region, including parts of Spain, Portugal, and Morocco. Dioonid plants are characterized by their rosette of leaves, which are often glossy and evergreen, and their tall, erect stems that bear clusters of small, star-shaped flowers. The flowers are typically white or cream-colored, and they are pollinated by insects.

Dioonid plants are often grown as ornamental plants in gardens and nurseries due to their attractive foliage and flowers. They are also used in landscaping for their ability to tolerate a wide range of soil conditions and their relatively low maintenance requirements. However, they are not typically grown for their edible fruits or seeds, unlike some other members of the Asparagaceae family.

The genus Dioon was first described by the French botanist René Louiche Desfontaines in 1813. There are currently three recognized species of Dioonid plants, including Dioon edule, Dioon spinulosum, and Dioon spinulosum var. spinulosum. Dioon edule is the most commonly cultivated species, and it is often referred to simply as "Dioon" in horticulture.
