FAQ
Is this the same as black-eyed Susan flower?
No. This is Thunbergia alata, a flowering vine. It is not Rudbeckia, the daisy-like black-eyed Susan perennial or annual.
How long do the vines get?
The source describes African Sunset as a fast climber with vines about 5-8 ft. long, ideal for supports, baskets, or trailing displays.
Can I overwinter it?
In cold climates it is usually grown as an annual, but stem cuttings may be rooted indoors in water or protected warmth for the next season.
