In the previous post about growing Black-Eyed Susan Vine I posted a picture of a developing seed pod on my Black-Eyed Susan Vine. If you're growing Black-Eyed Susan Vine then chances are good that soon you'll have Thunbergia alata seeds-if you know where to find them on the vine and how to collect them. Knowing how to collect Black-Eyed Susan Vine seeds is more important than knowing when to collect the seeds.
Black-Eyed Susan Vine flowers are tubular-shaped and pollinated by pollinators with long tongues. After the bloom fades you'll be able to tell whether it was pollinated or not within a day or two.
