About
Urceolina is a genus of South American plants in the amaryllis family native to Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Panama, and Peru. It has also been introduced to many South and Central American states, as well as India and Sri Lanka. The formerly accepted genera Eucharis and Caliphruria are now regarded as synonyms of this genus. Many species of this genus share the common name Amazon lily.
How to grow it
Urceolina amazonica, U. × grandiflora, and U. subedentata are the best-known and most generally cultivated species. It is propagated by removing the offsets, which may be done in spring, potting them singly in 15 cm pots. It requires good loamy soil, with enough sand to keep the compost open, and should have a good supply of water. A temperature of 18° to 20 °C during the night, and rising to 25 °C in the day. During summer growth is to be encouraged by repotting, but the plants should afterwards be slightly rested by removal to a night temperature of about 15 °C, water being withheld for a time, though they must not be left dry for too long, the plant being an evergreen. By the turn of the year they may again have more heat and more water, and this will probably induce them to flower. With a stock of the smaller plants to start them in succession, it is possible to have plants in flower all the year round.
