Hello Gabriel,
Echinocereus viereckii ssp morricalli is also present in my collection, but it is getting hard to spot among all those prickly pear cacti.
It is yet another of the beauties within the genus Echinocereus.
Hello Gabriel,
does that Mammillaria schumanni really have almost light purple (mauve) flowers or were the images perhaps taken in the evening or low light hours?
I did have a good-sized cactus a few years back, which did produce purplish blossoms. They had about the color of red cabbage.
Unfortunately, I did lose that cactus, a Ferocactus latispinus to a rot organism.
Either way, even if the flowers of the M. schumannii were pink, the cactus would still be a pretty plant.
