Two pouches are better than one! This Cypripedium parviflorum
var. pubescens produced two blooms on the same stem! These plants
started out a 5 years ago as just a few individual stems. They
are growing in my Ohio bog garden (USDA Zone 5). The soil is
equal parts sand, pine needles, peat moss (yes, sphagnum!) and
oak leaf mold. I dig a hole 24 inches deep and at least 2 feet
wide. I line the hole with two or three layers of strong white
greenhouse plastic. The substrate consists of gravel or cypress
mulch filled to a depth of 12 inches. The soil mix completes the
top twelve inches of the bog. To keep standing water out of the
root zone, I punch many holes in the sides of the plastic from
ground level down to about 8 inches below the soil level. Most of
my American Cyps are thriving in these types of bogs.
