One of the most stunningly beautiful of Dyckias with narrow arching silver leaves and massive, soft, comb-like spines in a graceful rosette. Newly published in only 2002, it is a narrow endemic species known from only one site in the southernmost Brazilian state of Rio Grade do Sul where it is native to basaltic rock outcrops in isolated mountainous interior. Our clone came to us from Constantino Gastaldi in adjacent Santa Catarina state, from seed produced in his private collection. Because the seed are from cultivated plants, he admonishes us that it is altogether possible that they are not pure delicata. However, in our seedling crop, all plants are consistent and all “look like” what a Dyckia delicata should look like at this stage.
