Clearly, this is a plant with issues defining itself, or deciding what it wants to be when it grows up. The mediaeval spiky weapons, fluffy yellow blossoms, sharper scarlet buds and green and burgundy leaves are all on the one plant.
I know how it must be thinking, some days - who AM I today????
I would of course tell you the name of this plant. If I knew.
Later: but I don't need to, because Pennie has named it in her comment. What a useful person Gwy is! Thank you!
I still think it's a weird brew of elements on one plant.
