Passiflora Species, Giant Granadilla. Passion Flower, Passion Vine

My plant is in a hanging basket on my back porch. I have to bring it inside during the winter as I live in Zone 7, East Tennessee. Last y...Read Moreear it barely grew so it was easy to move inside. This year it grew approximately ten feet or so but I successfully got it inside and after waiting patiently for two years it bloomed.
If you have a place to let it grow it is one of the most spectacular blooms I've ever seen.

I visited the Fruit and Spice Park in Miami (Homestead) last week; they have a good length of fenceline with this plant growing; I believ...Read Moree that it is this species. The rule in the park is that you CAN pick up fruit off the ground to taste; there was one fruit, a bit past its prime that I was able to taste. It had fermented a bit. The flowers smell like perfume. I plan to obtain one of these once I return home, although I will have to keep it indoors during the winter (Johnston County, NC).

There is great confusion of this plant with the much more hardy hybrid Passiflora x decaisneana. In Europe most nurseries still mislabel ...Read MoreP. x decaisneana as P. quadrangularis. On the other hand the real P. quadrangularis is a much more demanding plant, very sensitive to frost and looks really pitiful in the winter here. Even light frosts can kill it. If you don't live in the tropics and not have a heated greenhouse don't expect any fruit (except for South Florida probably). I can distinguish it from P. x decaisneana from the characteristic shape of it's leaves, similar looking to the common Hydrangea. It is noticeable that even Passiflora macrocarpa (aka P. 'Blue Moon') is much more hardy to near freezing low temperatures. By the way, there is still great confusion if P. quadrangularis 'Warmlands' is actually Passiflora macrocarpa (aka P. 'Blue Moon').

There was a discussion among Passiflora experts about the cultivar called 'Warmlands' some time ago. Logee's claimed to have discovered ...Read Morea new passiflora hybrid in San Diego and named it "Warmlands" only to find out later that it was not a new hybrid and it already had a name of Passiflora macrocarpa, also known as Passiflora quadrangularis. The correct name is Passiflora macrocarpa, but they did sell some as 'Warmlands' so the confusion may exist for some time.
