This is a lovely plant, very rare in cultivation, and difficult to keep unless the circumstances are most favourable. It is a native of moist warm woods in N. America, ranging over a considerable extent of the country, and luxuriates in the rich deep vegetable mould formed by the decomposed annual clothing of many generations of trees. The nearest approach to this that we can make in cultivation is a mixture of peat and loam with abundance of sand. Considerable depth of soil is required, and it should be well drained, but well supplied with water during the hot months of summer. The plant likes a warm position and also a little shade, but if so placed on rockwork as to enjoy a screen for an hour or two during the hottest part of the day, it will be quite sufficient. Shelter also is required from cutting winds, and the means adopted to secure this, whether by planting in hollows protected by either ledges or bushes, may be so adjusted as to afford the necessary amount of shade. Propagation may be effected by carefully dividing the roots, but it is one of those subjects which, when doing well, should not lightly be disturbed. The plant grows about 1 foot or 18 inches high, with numerous erect simple stems. The leaves are very broadly lance-shaped or acutely oval.

The flowers are long, tubular, brilliant scarlet externally and yellow within, but little of this is seen except on close examination, the external colour being that which is conspicuous, and the tube is divided at the mouth into five acute segments; they are borne in small clusters in the axils of the upper part of the stem, and appear in July and August.
