Oxblood Lilies

Hypoxis (hy-POK-sis)

Family: Hypoxidaceae Non-native Herbaceous (1-3 ft)

There are approximately 90 species in this genus, occurring nearly worldwide in the Hypoxidaceae family. The majority of the species occur in the southern hemisphere, with most in Africa. The scientific name is derived from the Greek words hypo , which translates to below and oxy , referring to the pointed fruit base. The plants can grow from corms, tubers, or rhizomes and can reach heights of 3 to 12 inches, spreading to form clumps. They tend to prefer full sun to partial shade and appear in most types of well-drained soils. Propagation is by seed or division. The yellow flowers consist of 6 yellow tepals that may have hairs, especially on the undersides and may be tinted in white, green or red on top or the undersides. The leaves vary per species and can be a cluster of lance-shaped, linear or thread-like leaves. Some species could be used in a pollinator or rock garden or as a ground cover. Insects, Diseases, and Other Plant Problems: No significant problems
