'China Girl', a pair with distinctively lighter-green foliage and chartreuse stems, are the most heat tolerant and cold hardy, due to being the progeny of a cross between Ilex cornuta (Chinese Holly, a large holly noted for its heat tolerance) and Ilex rugosa (Prostrate Holly, a low spreading holly noted for its cold hardiness). They also grow slightly more rapidly, but do not have as heavy of fruit set and the dark blue-green foliage of other hybrids. |
