First passionflowers and lots of questions
I have two vines, one purple and one red (caerulea & coccinea). Both beautiful, purple blooming well, first red bloom yesterday (finally) living on my deck in pots.
Here are my questions:
1. Do the blooms only last one day?
2. When it's time to bring them in can I just cut the vines back or will that shock them badly?
3. Can I overwinter them inside in a dormant state? (I do this with brugmansia - cut back, water about 1x/month, dark place.) I have poor window space for the winter months.
4. How much do these like to be fed during growing season?
Anything else I need to know?
