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. It is hardy to about USDA zones 7-8 and gets 6 to 10 tall. Flowers are in panicles similar to P. japonica. Whichever variety you choose, you can t go wrong.
