Rainbow- yellow- 27- A single petalled marigold Most of the marigolds in the garden are double petalled , but occasionally we have the single petalled one .
Sometimes the simple beauty of the single petalled flower is even more lovely that the super ruffled ones. I find the same with peonies. While I love the full ,bomb style flowers I have a special appreciation for the simpler Japanese style ones.
Your calendar is looking wonderful!
