A hybrid from Q Dyckia in Thailand. The parentage is Hechtia and Dyckia but the Hechtia characteristics are not seen. The inflorescence is like your typical Dyckia. Grows to 12 inches across. The leaves are narrow and armed with large spines. The leaf color is a glossy black and the spines are white. Grow in full sun to get optimum color.
Anything I ever ordered from Tropiflora always arrives promptly and in good shape, including this X Dycktia 'Satit 18', which looks very impressive but still cute. I love it! BTW - I also like to add here that if you ever have a question about a plant purchase - even acquired months ago - you will get a prompt answer from the very friendly staff.
