It's composed of:
- Antirrhinum majus, rocket variety
- Cerinthe retorta
- Erysimum linifolium 'Variegatum'
- Gomphrena decumbens 'Itsy Bitsy' (better known as 'Little Grapes')
There's a very small touch of the lemon color in the flower of the Cerinthe that picks up the color of the snapdragon, which is also echoed in the cream-colored variegation of the Erysimum. The flowers of the Gomphrena circle above like tiny satellites, emphasizing the purple edge of the Cerinthe's flowers.
I still haven't made up my mind as to whether or not I really like the Cerinthe retorta. The foliage is interesting but the flowers don't impress me as much as those of Cerinthe major.
However, I love the Gomphrena, which has been blooming non-stop since I planted it in June.
Best wishes for a productive week in your garden!
