Granadilla flowers

Also Passion Flowers, granadillas sometimes being known as passion fruit; named for a spiritual passion rather than some more earthly variety.

We had an amazingly prolific plant that we causally introduced into a flower bed on the sidewalk outside our house. A friend, who was doing some work  on the house, had the idea of building a framework over the sidewalk for the plant to grow on, which it did, with gay abandon. In a single season it completely covered the framework, quite an impressive site. So much so that the City of Seattle took exception to it and after months of wrangling we were finally forced to take it down. There's a message there somewhere, though what it is seems to escape me.
