Still Cactus Bloom Season
Yowza, that’s a vibrant yellow.
I recently posted a less vibrant yellow flower picture from this species. I also mentioned it used to be a notocactus. But I forgot to mention that Parodia was described and named in 1923 by Spegazzini. Also, while they are no longer in the notocactus genus (since the genus has been eliminated) it is still in the Tribe Notocacteae.
