Rhodophiala is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae). It consists in 28 South American species distributed in southern Brazil, Argentina, and, specially, in Chile.

Description

Members of Rhodophiala look like small-flowered hippeastrums or multiflowered habranthi. It has been placed in Hippeastrum, in the former Amaryllis or even in a new genus Rhodolirium. The foliage, narrowly strap-shaped leaves, is very different from all known hippeastrums and rather resembles that of the large flowered Habranthus or Zephyranthes.

Uses

Several species of ths genus are cultivated as ornamental plants. From the cultivation point of view Rhodophiala species can be separated in four groups:

* The autumn/winter/spring growing Chilean species that need a dry summer dormancy, like R. bagnoldi, R. ovalleana, R. splendens, and R. advena. All of them are better grown under frost free conditions although several of them can be quite tolerant to cooler conditions. Some flower in fall without leaves, others in spring together with leaves growth.
* The spring/summer growing species from the Andes of both Chile and Argentina. They spend a long very dry winter unders snow. They include R. rhodolirion, R. araucana, R. andicola, and R. elwesii. These need cool conditions during almost all the year but are half hardy in countries like England. Flowers are produced in spring together with the leaves in most cases.
* The autumn/winter/spring growing Rhodophiala bifida from Uruguay and Argentina. It is dormant in summer but it receives rains all the year. Therefore, it is intolerant to summer drought, that would make it lose the roots. It is quite hardy. Summers always long and hot in the wild. There is an interesting range of color forms in this easy species. As a rule, a population has flowers of a single color with few, if any, variant. It flowers in late summer before foliage production.[12]
