About
Brunfelsia pauciflora is a species of flowering plant in the family Solanaceae, the nightshades. It is endemic to Brazil, and it is grown in cultivation. A shrubby perennial plant grown in gardens, its common names include yesterday-today-and-tomorrow, morning-noon-and-night, kiss-me-quick, and Brazil raintree.
Cultivars bred for ornamental use include the common 'Eximia', the smaller, more floriferous 'Floribunda', and 'Macrantha', which has larger flowers without white throats. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Safety
The roots of several species corresponding to the genus Brunfelsia contain substances whose consumption can cause problems in human health according to the compendium published by the European Food Safety Authority in 2012. In particular they contain indole alkaloids derived from Beta-carboline such as harmine, tetrahydroharmine, harmaline, manacin, manacein, and dimethyltryptamine and amidine derivatives such as pyrrole 3-carboxamidine.
Where it grows
It occurs mainly on the Atlantic facing slopes of the Serra do Mar in southeastern Brazil. The distribution areas are located in the state of Rio de Janeiro to Santa Catarina, where they range from sea level to altitudes of 1,500 m (4,900 ft). Most are found in pluvial rainforests with an annual rainfall of up to 1,600 mm (63 in). One finds plants of the kind on shady river banks and ravines, as well as in forests in damp, well draining soils.
