A general term for the genus Solandra in the Solanaceae family (APG classification: Solanaceae). It is a shrub or woody vine, with about 10 species distributed from Mexico to tropical America. The commonly cultivated trumpet banana S. grandiflora Sw. is native to Mexico and the West Indies, and can reach over 10 meters in its native habitat. In a greenhouse, it grows to 2-3 meters tall and blooms from winter to spring. The flowers are large, trumpet-shaped, over 20 centimeters long, fragrant, whitish-yellow at first, gradually turning yellowish-brown, and wilting in 4-5 days. The turmeric trumpet banana ( S. maxima PSGreen) is hairless on all plants, and the leaves are long-stalked, oval, and shiny. The flowers are large, trumpet-shaped, about 25 centimeters long, and have a sweet scent. The color of the flowers changes from yellow to yellowish-brown in a few days. In Okinawa Prefecture, it blooms in winter and overwinter at 8-10°C. It needs plenty of sunlight. From summer to autumn, the plant is almost dormant, so water sparingly. It is best propagated by cuttings. [Takabayashi Masatoshi June 21, 2021] Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
