The blue passionflower (Passiflora, maybe 'Incense'?) that I rescused from our local garden center clearance pile has finally recovered from transplant shock, and is treating us to a beautiful bloom now nearly once a day. Many of them have been hidden in an amongst the foliage, but this morning I was able to get a clear photo of a freshly opened flower. It would be nearly impossible to adequately describe its unique form, so I will let this photo speak for itself.
So greatful to have a friend with a conservatory in which to overwinter this and my other tropical vines. We'll hopefully be enjoying this Passiflora for many years to come.
Note (11/20/09): Thanks to Simon Eade for help in identifying this variety. The nursery tag said "blue passionflower".
