We used to eat these vegetables, actually flowers (svanjana & kachnar). What are their english names?
Botanical name for kachnar is Bauhinia tormentosa. It is a auyvedic or herbal plant and can be used as a gargle for sore throats, as a paste for skin diseases, or internally as a remedy for diarrhoea. Botanical name of vanjana is Bignonia chelonoides; bignonia is usually called as trumpet flower in English. Hope this info helps. Cheers.
