Lisianthus (Greek compound). Gentianaceae. About 10 species in the W. Indies and Cent. Amer., herbs or shrubs with mostly rather large yellow-green, brown-black or rarely white fls. in cymose clusters, and opposite lvs. None of the species seems to be in the trade, although L. Russellianus, Hook. (L. erythropensis, Hort.), is recorded as a cult, plant in garden literature; this plant is Eustoma Russellianum, Griseb., growing on plains Neb. to La. and Mex. Glaucous: st. simple, or with a few opposite branches: lvs. opposite, connate, ovate or ovate -oblong, 3-5-nerved: fls. panicled, as large as a tulip; lobes obovate, spreading; stigma of 2 very large, green, velvety, spreading plates: pod oblong; seeds minute, pale brown. B.M. 3626. G.C. III. 4:240. R.H. 1863:51; 1881, p. 189. G.M. 49:479. Gn. 70, p. 77. G. 25:292. G.W. 11, p. 138. H.F. II. 4:240. It is a tender annual and grows 1 ½ ft. high, producing its 5-lobed, purple, dark-eyed fls. in summer and fall. Under favorable conditions the fls. are 4 in. across, as many as 10 or 11 on a plant, and individual blossoms have been known to last three weeks. According to F. L. Harris, in the Old World it is usually treated as a cool greenhouse subject, being sown in early spring for summer and autumn bloom. The seed should be sown carefully, and at every stage of the plant's growth over-watering should be guarded against. The seedlings are very likely to damp-off. When they are ready for transplanting from the seedbeds, use small pots. When larger plants are needed, place them in a light, airy place and give generous bottom heat. For soil, use good loam, sand and well- rotted manure. The above text is from the Standard Cyclopedia of Horticulture.
