Brugmansia suaveolens is a semi-woody shrub or small tree, growing up to 3–5 m tall, often with a many-branched trunk. The flowers are about 24–32 cm long and shaped like trumpets. The flowers are usually white but may be yellow or pink and hang downward.
The Latin specific epithet suaveolens means “with a sweet fragrance”.
First discovered by Alexander von Humboldt and Aimé Bonpland, Brugmansia suaveolens was first formally described and published by Carl Ludwig Willdenow in 1809 as Datura suaveolens. In 1823, Friedrich von Berchtold and Jan Presl transferred these to Brugmansia suaveolens. Local common names include Maikoa, Huanduc, Maikiua, Tompeta del jucio, Tsuaak, Toe, Wahashupa, Peji, Bikut, Ohuetagi, Ain-vai, Baikua, Canachiari, and Ishauna.
Brugmansia suavolens was originally endemic to the coastal rainforests of south-east Brazil, where it grows below 1,000 m along river banks and forest edges with warm temperatures, high humidity, and heavy rainfall.
