I was so impressed with myself that I recognized this as a purple version of Holmskioldia, not even knowing if there was such a thing, but then it turns out this used to be called something like Holmskioldia tettensis, but now it has been renamed Karomia tettensis. Or else it's Karomia speciosa. Or are they synonyms? I've seen pages with both species (tettensis and speciosa) listed, and I've seen pages that say they're the same. I'd love to know which to call this.
