UL, CSA, ETL and CE: What They Mean. If you look on the back panel of Crown amplifiers or PIP modules, you will see a silk-screened certification mark or logo such as UL, CSA, ETL or CE. What do these certification marks mean? Basically they are stamps of approval.
Peony is a plant. The root and, less commonly, the flower and seed are used to make medicine. Peony is sometimes called red peony and white peony. This does not refer to the color of the flowers, which are pink, red, purple, or white, but to the color of the processed root. Peony is used for gout, osteoarthritis, fever, respiratory tract illnesses, and cough.
Plant herbaceous peonies so the buds are 2 in. (5 cm) from the surface. Place the clump of peony tubers in the hole, with the small buds or eyes pointed upward, and the long roots pointed downward. The buds should be no more than 2 in. (5 cm) from the surface, or the plant may fail to emerge.
