kidfishing said:I bought 4 "ANNUAL" Passion Flowers from a nursery 4-5 years ago, they are still alive but have never had a single flower.
What's wrong with them?
I'd speculate that the sellers call any that aren't reliably hardy "annuals".
I give mine lots of nutrients during the flowering period; nitrogen enhanced water once per week, and a heavy phosphorous blend a few days later...repeat and repeat...
My two vines are at least 16' long, and half as wide, with tons of buds and blooms. The buds only open after a good dose of water though.
