A few years ago, I noticed new plants that appeared in the fields along the path to the lake, where I usually walk. They were bright yellow, noticeable plants that almost filled the whole field. One day on my way I met a man and he told me many interesting things about ones. They are called goldenrods (Lat. Solidago). They are medicinal plants, and are used as an anti-inflammatory drug. From time to time, I drink goldenrod's tea. The taste of tea is quite pleasant for me.
Beautiful flower @albaevg, thank you.
Thank you, @zavz9t, for good words!
