Another, White Water is a low growing form with bright yellow new growth. Others have been bred to stay small and are suitable for the rock garden. There are at least two cultivars with variegated leaves. I have Variegata , which has a green and white leaf and white flowers, really quite lovely. Another is Flaming Silver , which sounds exceptionally neat.
New leaves are red, edged in pink which matures to a distinctive silver-white.
P. floribunda , the Mountain Pieris, is native from Virginia to Georgia. Unlike P. japonica, the flowers are in upright, pyramidal clusters. Form is low and rounded with rather stiff branches. It will get up to 6 high with an equal spread. From what Dirr says, this species is not as prone to Lace Bug attack and it is tolerant of a higher pH soil than most others.
