Flower sepal question?
What is the difference between persistent sepals and deciduous sepals? I'm trying to identify a flower, but I don't know how to tell if it has persistent or deciduous sepals.
I assume persistent sepals stay on, but for how long?
And I assume deciduous sepals fall off but when? Seems like it could easily be confused, I want to know the exact way of telling the difference.
Any help would be appreciated.
