Thunbergia grandiflora

Amazing !

I agree :-)

This is another vine I love!!! However, it's much too aggressive for my garden. Believe-it-or-not, it can grow to this size in two years here in San Diego.

I believe it. It seems to be aggresive here as well. Lots of people grow it mixed with bugenvilias

Another issue with Thunbergia species, is that they pop up everywhere. I used to have Thunbergia 'Blushing Susan', I dug it out about two years ago...and still have hundreds popping up all over the yard and in my potted plants.

:-(

Thunbergia mysorensis is the exception. I've never seen it naturalize here or any other place.

Had to google this.They are astonishing plants .

I have several pics of Thunbergia mysorensis posted on GoY. The San Diego Zoo has many beautiful ones which bloom all year.
