The genus Fritillaria L. (Liliaceae) has around 140 species, all of which occur in the temperate regions of the northern hemisphere. More than half of those species are protected and are in danger of becoming extinct, mainly due to changes in the area where they occur and through use for medicinal purposes or as an ornamental plant. In collaboration with the Botanical Garden of the University of Warsaw, the Hortus shows a number of information panels about this genus. Extra Fritillaria native are also planted in the garden, and some Fritillaria will be blooming in the Bulb glasshouse. Do not expect a massive bloom, but you will be able to make beautiful pictures and see a few jewels of flowers.
