This is a stove plant of great beauty, much admired for its zebra-like foliage, as also its brilliant scarlet flowers. The plant sinks into a state of perfect rest after the manner of the Gloxinia family, and the dry roots must be taken out of the old and dry soil in March and repotted. This plant requires a generous soil, one composed of equal parts of sound loam, old manure, a free peat, and some silver sand, will suit it well. The chief thing is to give it plenty of heat; few plants enjoy more. To grow it in high perfection, with vivid coloring, from 70° to 80° are necessary. Another point is to allow it plenty of air moisture. Bottom heat is of great importance too, especially in the earlier stages of its growth, 70° to 80° if possible. Most of this tribe enjoy a partial shade, or, at least, are averse to intense sunlight, which is apt to deface the foliage. All possible care should be taken at all times not to injure the latter; therefore, when moved, cautious handling is necessary.
When in blossom, they will do very well in the very warmest spot of a greenhouse, although an intermediate house would suit them better.
