No, it is not a trumpet vine (Campsis Radicans, I hate!). Thunbergia Grandiflora, too my knowledge does not spread via root sprouts. Nor does it produce any seeds (for me, anyway).

I first saw this flower on a huge harbor in an old Magnolia Nursery estate, years ago when on a Master Gardener field trip. It was planted with Passiflora Incense. I already had Passiflora Incense, but didn't have the Thunbergia Grandiflora. The new owner, who graciously sponsored the visit, gave me cuttings which I rooted, and now have many.

I adore this vine. Can you tell?
