Over a 10 year period, since 2014, Mitch Magee has been trying to develop a hybrid between the red and blue hollies from his farm in Poplarville, Mississippi. He took a cross between the Liberty Holly (Ilex x ‘Conty’) and a Blue Prince Holly (Ilex x meserveae ‘Blue Prince’) and the result is a dense, upright, conical growth habit with dark bluish-green leaves which he named the Monarch Holly. This new holly took the best attributes from each of its parents with the dark green foliage and cold hardiness from the Blue Prince and the dense, compact and heat tolerance of the Liberty Holly. It can be installed as a privacy screen, areas that are very narrow or even as solitary specimens. They can adapt to many soil types from sand to clay and from moist to very dry. Monarch Hollies also grown well in full sun to part shade.
