The huge (4-5” across) flowers of this plant are spectacular. They are a clear lemon yellow, cup shaped, and made of the most delicate tissue. The buds are also beautiful; long, tapered, red-blushed green, and carried on red stems. Wow! Added to that are lance shaped, pointed, dark green leaves that grow in bunches along the trailing stems. That is not all; after the flowers are finished they are followed by large, winged seed capsules that are beautiful in flower arrangements. I like to pair this primrose with threadleaf coreopsis (Coreopsis verticillata ‘Moonbeam’) that is the same color and shape but contrasts in size. To be entirely truthful I will have to admit that this plant does not like my heat and humidity and I have to replace it on a regular basis, but it is worth it.
