Thunbergia alata 'Blushing Susie' seeds

Thunbergia alata (black-eyed Susan vine, suzanne aux yeux noirs, oeil de suzanne) is a perennial vine native to eastern Africa, grown as an annual here in Toronto.

Despite the similarity of the common names, thunbergia should not be confused with our native black-eyed Susan, Rudbeckia hirta (rudbeckie dressée). Unlike rudbeckia, thunbergia is not a composite flower; rather it has trumpet-shaped flowers with five petals and an almost black throat. The species has light yellow-orange petals, however cultivars are available in yellow, white, and in the case of 'Blushing Susie', peachy-pink.

I got these seeds from Park Seed.

Veseys claims this plant attracts hummingbirds, however I haven't been able to find any photos of hummingbirds visiting T. alata so I'm a bit sceptical.
