Melinis nerviglumis (Ruby Grass) - A small semi-evergreen cool-season grass from S. Africa that forms a tidy 1 foot tall clump. It has blue-green foliage that turns purplish-red in the fall and showy pink flowers that rise a foot above the foliage in the spring and summer with spent flowers still attractive into winter. Best in full sun with regular water in a well-drained soil but tolerates considerable periods without irrigation and near seaside conditions. Is hardy to around 20 F and perennial in gardens in USDA Zones 8 and above but useful as an annual in colder climates. Cut back in fall to midwinter to allow fresh new foliage to emerge in early spring. A very attractive grass massed or scattered in a border planting or as a container specimen. This grass is called "one of the showiest of the small flowering grasses" by John Greenlee in his "Encyclopedia of Flowering Grasses". Ruby Grass is native to large areas of Africa south of the Sahara and also in Madagascar. There are several interpretations for the entomology of the genus name. One thought is that it is derived from the Greek 'melas' meaning "black" for its black seeds but another thought is that it is from the Latin 'mel' meaning honey for the sweet aroma some species have. The specific epithet is in reference to the veins on the glume (flower bracts). We have grown this plant since 1997 and early on used its older name Rhynchelytrum neriglume. This same plant is marketed under the names 'Pink Crystals' and 'Savannah' and besides Ruby Grass is commonly called Bristle-leaved Red Top. It should not be confused with the related Melinis repens that has naturalized in disturbed sites along the California coast.  The information on this page is based on our research that has been conducted on this plant in our nursery library, from online sources, and from observations made of the crops growing in the nursery, plants in the nursery's garden and those in other gardens where we have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Melinis nerviglumis.
