I was ignoring that plant, then it flowered. and I got stuck. Guilty as charged.
Passiflora caerulea (photo taken today):

That's beautiful! Passies are one of my favorites.
How long did it take to flower?

Grown from seed, 1st year potted, planted into ground (SE house corner) spring 2007.
Appears more cold tolerant than I thought...everyone else known to me grows them in a pot, passy can not survive in the ground here, they told me...
Flowered for the 1st time this year. No fruits set so far.
Maybe Caerulea also needs other passy nearby...
None of insects/bugs visits that flowers...???
Grows like crazy since solstice... Seems to be the fastest grower I have.
And I have kiwis, grape wines, honeysucles, tecoma, glicinia...
I have to do some pinching/cutting every few days...
About 10 new sprouts showed up from the ground these days...
Fence seems to be more appropriate place for passy, not here - with poor kiwi, grape wine, poncirus being too close...
Amasing plant it is!
I want more them and I can not wait for fruits or spring to divide/dig sprouts, a few cuttings in a glass of water since yesterday..
