Blue star

The Blue star (Amsonia orientalis) is a species in the genus Amsonia. It is currently classified as Critically Endangered on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common Lamb'S-Quarters

Common Lamb's-Quarters (<em>Chenopodium album</em>) is an annual herb in the family Amaranthaceae, classified as Least Concern on the IUCN Red List. It has an exceptionally broad global distribution, native to twelve African countries, seventeen Asian countries, twenty-one European countries, four North American countries, Australia in Oceania, and seven South American countries. The species occupies nine distinct biome types including tropical and subtropical moist broadleaf forests, flooded grasslands, and desert environments. It typically thrives in disturbed, nutrient-rich substrates such as agricultural fields, roadsides, garden beds, and waste ground, making it one of the world's most widespread ruderal plants. The young leaves are edible and have been used as a leafy vegetable and pot herb across many cultures historically. Its remarkable adaptability to a wide range of climatic zones and habitat types explains both its cosmopolitan distribution and stable conservation status. Biological traits of this species remain poorly documented in the scientific literature.
