The P. 'Purple Tiger' in my bedroom is blooming now. It's lighter colored than the plant that's outdoors.
Passiflora 'Purple Tiger' Bud
'Purple Tiger' flower from below
This plant shares a pot with P. phoenicia,P. alata 'Hirt's Ruby Glow', P. 'Flying V', P. candollei and P. vitifolia 'Scarlet Flame'.
I'm not certain that there is enough light and humidity in my room for all these plants: the batwing passionflowers have both lost growth tips, possibly because the air is too dry. 'Purple Tiger' is supposed to by a large and fast-growing clone, so I built a climbing structure up the wall, that I will extend across the ceiling if it ever comes to that.
I moved to a new apartment in San Francisco with a large balcony. I've planted a hummingbird garden and many passion flowers. One of the first passionflowers to bloom was a Passiflora xdecaisneana 'Purple Tiger'.
P. x decaisneana is listed as P. alata x P. quadrangularis, two similar looking species with entire leaves and long purple and white filaments. This hybrid was first made in the 19th Century and was named for the botanist Joseph Decaisne. The flowers are fragrant and tend to hang down below the leaves
Hummingbirds visit the garden to feed everyday, and sometimes even stop to rest.
