Is there anyone who has grown this plant and saved the seeds? I want to know if it will come back true from saved seed. I really want to know the answer to this, because there are so few places that sell the pink variety, and one of the places I looked charges almost $14 for two plants, and $13 for shipping!!! In my zone this is an annual, so that seems VERY expensive to me. But if I knew it would come back true from seed, I wouldn't mind making that first time investment!

You could also take cuttings from the expensive plants.
I have never seen that one up here.

Thanks so much for that suggestion Caroline--that just might work! When I started some of the Blushing Susie variety from seed, in the house, they started getting too long and twining around the ones next to them. So, I had to cut them back, but I hated to throw out those cuttings, so I decided to throw them in a vase with some water just to see what would happen. Those cuttings were VERY small in diameter, practically hair like, so I wasn't expecting much. I was totally amazed when after a few weeks I saw roots on all the cuttings!!! So, if I wait till really late in the season and take some cuttings, I might be able to overwinter them. And, I'm thinking, I'd save some of the seeds and try planting them too, just to see what I get.

I had this variety last year and the regular orange variety. The pollinators loved the orange one I grew from seed but completely ignored the pink one I bought from Select Seeds and it made no seeds and the orange one made a ton. The plants were fairly inexpensive, though and it's very pretty!

The only roses that I know of that will come back true from seed are the species roses. Cuttings are the way to go.

I think rose is describing the color of the blooms. This plant seems to have 2 entries in the database on this site?:
Black Eyed Susan Vine (Thunbergia 'Arizona Rose Sensation')
Black Eyed Susan Vine (Thunbergia alata Sunny Suzy® Rose Sensation)

I would try to save it too. Gorgeous! First-year perennials rarely offer a full show of their potential the first year, though sometimes it's just a matter of size or overall mass.

Yes, that pink one is the one I bought from Select Seed last year. I kept it in a hanging basket on my patio and it climbed all over the place and made a ton of blooms. It wasn't very expensive at all as I recall. Maybe 7 dollars. It didn't set any seed, though.

So if it does not set seeds ……it is propagated by cuttings.
The plants could be grown as a houseplant where winters are cold.
