Cestrum Nocturnum
Henna, or Menhdi as it is called in Hindi, is a symbol of festivity in India. It is especially associated with marriage in north India. Its leaves produce the henna or alhenna of the Arabs (cyprus of the ancients), a yellow die which is used in Egypt and elsewhere by women to color their nails, and by men to die their beards. The fragrance is best from a distance when mixed with air. Cestrum nocturnum (common names include night-blooming jessamine, night-blooming jasmine, night-blooming cestrum, and raatrani), is a species of Cestrum in the plant family Solanaceae (the potato family). It is native to the West Indies, but naturalized in South Asia
