I planted a passionflower last spring and it grew like gangbusters. Unfortunately, it didn't bloom until mid August (then stayed in bloom until the frosts of late October.)

I noticed that the clematis it is planted beside is breaking dormancy as I type this message. When may I expect my passionflower to start growing? Is there a specific temperature? Oh, and when can I expect it to start blooming; now that it's been established for a year?

TIA!
