India encompasses a wide range of biomes: desert, high mountains, highlands, tropical and temperate forests, swamplands, plains, grasslands, areas surrounding rivers, as well as island archipelago. Officially, three out of the 36 Biodiversity Hotspots in the world are present in India: the Himalayas, the Western Ghats, and the Indo-Burma region. To these may be added the Sundarbans and the Terrai-Duar Savannah grasslands for their unique foliage and animal species. These hotspots have numerous endemic species. Nearly 5% of India's total area is formally classified under protected areas.
The flora of India is one of the richest in the world due to the wide range of climate, topology and habitat in the country. There are estimated to be over 18,000 species of flowering plants in India, which constitute some 6-7 percent of the total plant species in the world. India is home to more than 50,000 species of plants, including a variety of endemics. The use of plants as a source of medicines has been an integral part of life in India from the earliest times. There are more than 3000 Indian plant species officially documented as possessing into eight main floristic regions : Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar and the Andaman Islands.

In the UK, B. crispa was accorded the Royal Horticultural Society's Award of Merit in 1961. However, the species is not entirely cold-hardy, and thus its popularity is not as ubiquitous as it might otherwise be.
