@tbendl The colour should be orange and it is a very beautiful flower, just perfect for next to your pond. They like moisture. It took me a 3-year wait to get to see them flowers. I bought 3 plants from ebay. Well chuffed and they have soooo many flowers. A vivid orange but my panny hasn't got enough details whilst Samsung has got details, but the viewfinder turns the colour to yellow
So I took pics with the 2 cameras.
It belongs to the Ranunculaceae family. If you want to buy, make sure it is Trollius Chinensis, not Europeana. I love mine no end. You can see my obsession. Need to tidy up my strepts before they get killed by 26 or 30C in my lean to..
In fact,
@Larisa also has a beautiful one, a few pages back. The colour is divine.
