Gasteria Nigracanus
The Gasterias get their botanical name from their flowers, which are shaped like a stomach (“gaster” being Latin for stomach”), but I think it’s their leaves that make them really interesting. The thick, fleshy leaves grow out of the center, so if you look at them from the top they sort of look like they’re sticking their tongues out at you (which is probably why some people call them “cow’s tongue”).
This one is Gasteria nigracanus, which really likes the heat of late summer and shows it by rocking some cool salmon pink, green and yellow leaves.
