Julie. I don't know about that "great" statement. Just telling about my experiences, sometimes good and often not so good.
Here is my all-time favorite Celadine. It bloomed the first time in Sept. 2014, and now is blooming again. It is the Plumeria Rubra Celadine var. Ramsey. The flowers are about twice the size of the average Celadine flower and almost all yellow. Last year the yellow was more intense, perhaps a difference in blooming time makes the yellow a bit lighter this time of year. The fragrance is all-Celadine and the leaf pattern gives it away. Now, every time one comes in bloom, I am looking for a seed-pod. I have been smitten!
