FLAMBEAU. A Tree Peony hybrid by Emile Lemoine in 1930 Many early Tree Peony hybrids with delavayi or lutea in their ancestry inherit a tendency to hang their flower-heads. Whilst the heavy, double nature and size of some of them contribute to this behaviour, it will be noticed that it is evident on unopened buds as shown here, but also in the unopened and opened buds of the small single-flowered delavayi. Conseqeuntly, it cannot be solely attributed to the weight of the double flower. This plant, Flambeau, is particularly affected, and the flowers cannot be seen unless physically propped up.
