Ribbed fringepod (Thysanocarpus radians, formerly T. curvipes) is an intriguing annual native to California and reportedly found in a few other parts of western North America. It’s a delicate little thing, with very slender stems typically 12 to 18 inches tall and tiny, barely noticeable blooms. Its primary beauty comes from its small but showy seedpods, with a flat, circular, green center surrounded by a white ring with radiating pink stripes. It thrives in cool weather, doing its thing in spring and then disappearing as soon as hot weather arrives. The seedpods do not hold their colors as they dry on the plant; I don’t know if they would if silica-dried.
Honestly, this is not a good choice if you are looking for a high-impact plant. You pretty much need to get on your knees to appreciate it, or else grow it in a container in a raised position. (Siting it where the pods will be backlit shows them off to best advantage, by the way.) If you enjoy growing rare plants and appreciate that beautiful things don’t have to last forever to be worthwhile, then I think you will love it as much as I do. It’s an exquisite little gem for full sun to light shade.
I was lucky enough to get a few seeds of ribbed fringepod and grew it for the first time in spring of 2019. I keeping most of the small harvest I get each year to grow out more plants the following year, but so many people have expressed interest in growing this plant that I am parting with a few seeds here. Please, if you get some, collect the seeds from your plants and share them with others! It is practically impossible to find them in the trade.
2022-collected seeds are sold out. I hope to collect again in mid to late June 2023. Each packet contains at least 10 seeds.
Please read the germination information as well before ordering.
