This trumpet has a very fetching, not sulfury nor school bus yellow color, we have had in the border for around six years, so we were surprised that it became available this season. The cup casts a white penumbra on the petals, but not substantial enough to classify it a reverse bi-color. Booms out of the leaves, Unregistered, we are curious if it will end up as Super Citron, the fruit, rather then Citroen the automobile.
