It's a Thunbergia mysorensis.
Great vine!
Blooms all summer into fall here in St. Petersburg, Fla.
This looks like an old one that never got cut back.
Mine on the other hand gets cuts back
to the main stem every spring - Feb/March here.
Looks cool when you grow them on a walk-thru trellis
that the flowers can drop down from.
I got my from Logees several years ago.........cheryl

thank you for the quick reply. I found it at logees and I also got a diff vine along with it. Do you propagate your somehow? Is it easy to reprodu e from cuttings? Any tips you can offer is appreciated. Thanks!

The old stems will root in perlite and C. peat
either by a cuttings (or air layering).
I usually start about a dozen or so every spring,
when they are starting to put out new leaves.
Same time I'm cutting it back.

Another vine that I just love that Logees now carries
is the Nong Noch Vine (Petraeovitex bambusetorum).
Brilliant 1-2 foot yellow blooms that stay
on the vine for month(s)!
---No, I don't work for them.
Wish I did!............cheryl
