My original seeds came directly from the USDA seed bank and grew true to their description. A very unusual pube indeed. I think all 1st year blossoms are 5-lobed. Grape-sized and very hot. The only C. pubescens of over 40 varieties that I have been unable to self so be sure to grow 2 plants if you want pods & pure seed. Extremely prolific producer and will set pods in higher temperatures than any other pube I have grown. Also the fastest of any from seed start to ripe pods.
Sorry to say that I can't share seeds this year. I will isolate a pair of plants this summer and save seeds. All my seeds were donated a couple years ago.
