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.
These peonies produce tree peony flowers and leaves on plants that behave like herbaceous peonies, dying down to the ground in winter and reemerging each spring. A mature plant may produce 50 or more dinner-plate sized flowers on strong short stems that do not require staking.
