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.
Germinate Peony Seeds. Collect peony seeds from plant pods when the pods begin to open and seed coats are dark. The best time to collect is between July and September depending on the variety and climate. In dry climates, maturing happens earlier. Place the seeds in water for several days. Change the water daily to prevent disease. Remove seeds that are rotted or mushy.
