Name: Elaine Sarasota, Fl The one constant in life is change
The Cypress Vine has very fine, airy foliage so it seems as if it wouldn't have trouble drying to prevent mildew. I haven't seen anything like that here either.
Don't remember about the Cardinal Climber as I grew it in Utah years ago. Very dry air there in summer, though.
