When you say vining, do you mean trailing? As in growing all over the ground?
When you ask how long they bloom; do you mean how many months there are flowers on the plant or do you mean *when* do they bloom?
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others. ~~ Sharon Brown
