Dragon fruit (Selenicereus undatus) is a fast-growing climbing cactus grown for its vivid pink-skinned, sweet, mildly refreshing fruit with white or red flesh dotted with tiny seeds. A low-water, high-value crop, it thrives in hot climates on sturdy poles or trellises and bears large, fragrant night-blooming white flowers. India's cultivation, branded Kamalam, is expanding rapidly in Gujarat, Maharashtra, Karnataka and Andhra Pradesh. Tolerant of drought and poor soils but intolerant of waterlogging and frost, dragon fruit is a profitable, ornamental and easy-care fruit crop for warm Indian regions.
