We haven't mentioned the medicinal uses of passionflower:  it is a gentle
calming herb.  It contains a mild MAO inhibitor, so it may interact with
psychiatric medications.

I'm growing a hybrid between the North American *P. Incarnata* and  *P.* *
cinnicata*.  This is a fairly common ornamental hybrid.

The plant doesn't seem to mind the heat of the full sun in Central NC,
although I have more clay in my soil than it sounds like Michael has.  The
flowers are wonderful, I've used the leaves and flowers to make a gently
sedative tea.  The fruits are the size of a small lemon and very acidic.
I've only harvested about a dozen fruits from a seven foot vine, but this is
more productive and better tasting fruit than the native *P Incarnata.*

In temperate climates, I would recommend passionflowers for beauty and
medicine, fruit is a secondary benefit.
