Chinese holly
Ilex cornuta
Chinese holly (Ilex cornuta) is the only plant in this holly group that is not from here, and that is the first thing to say about it. It is native to eastern China and Korea, it is sold across the American South by the pallet, and Missouri Botanical Garden records plainly that "it has naturalized from garden plantings in North Carolina and Alabama". Kew's data adds introduced occurrences in Alabama, Arkansas, California, Florida, Louisiana, both Carolinas and Tennessee, and the mechanism is the plant's own selling point: birds eat the showy red drupes and carry the seed into woodland edges. On its merits it is a genuinely tough broadleaf evergreen - 8 to 15 feet each way, heat and drought tolerant, deer-proof, comfortable in city conditions, and carrying the most distinctive leaf in the genus, a stiff rectangular blade to four inches with three big spines at the blunt end rather than the wavy spined outline of English holly. The catch beyond the escape risk is cold: it is zone 7 to 9, and Missouri Botanical Garden says flatly that "winter hardiness is a significant problem in St. Louis". Set against inkberry, yaupon and possumhaw in this batch, it is the one whose wildlife value stops at the fruit.
