Thank you Annette. It can be Gardenia. I would be lovely. The flowers are really similar, but your stems look much stronger.
The old plant from the flower show was more than 50 years old, but it still had small flowers, about 4 inches. We shall see what will happen next year. In any case, I love the peony.
Your Gardenia is beautiful. I wish I have more space for one like yours.
