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.
Peonies can be classified by both plant growth habit and flower type. Plant growth types are Herbaceous (nonwoody), Tree (shrub), and Itoh (or Intersectional), which is intermediate between herbaceous and tree forms.In winter herbaceous peonies die back to their underground parts, whereas tree peonies lose their leaves but retain viable woody stems above ground.ree peonies can be propagated by grafting, division, seed, and from cuttings, although root grafting is most common commercially. Herbaceous peonies such as Paeonia lactiflora, will die back to ground level each autumn.
