Colmunea - Colmunea

It is an evergreen herb of the Gesneriaceae family (APG classification: Gesneriaceae), with about 200 species growing epiphytically in the rainforests of tropical America. As indoor horticulture becomes more popular, it is expected to be cultivated as a hanging pot. There are many hybrids as well as original species, and the possibility of interspecific hybridization is high. C. arguta CVMort. is native to Panama. It has long, drooping stems and densely growing long triangular leaves. The flowers are 6 to 7 centimeters long, open widely at the tip, and are orange-red in color. C. × stavanger also has drooping stems and produces solitary scarlet flowers in the leaf axils from winter to spring. C. mortonii Raym. is a short, upright plant with scarlet flowers 6 to 8 centimeters long. C. × kewensis hort. is a horizontal plant, sturdy, and produces good flowers. Propagate by cutting in April or May, pinch off the cuttings to shape them. Planting in sphagnum moss makes it easy to grow.
