Astrophytum plant story

Botanical name: Astrophytum myriostigma

Common Name(s): Bishop’s Hat, Star Cactus, Fossil Cactus 

The Astrophytum myriostigma, commonly referred to as the Bishop's Hat or Star Cactus is a fun and unique cactus! It derives its names from its distinct star-shaped structure and dome-like appearance.

What makes this plant stand out is that not one cactus is alike! Each plant displays 3-7 defined ribs and differs in coloration, from pristine white to vibrant green. Unlike the stereotypical image of spiky and prickly cacti, the Bishop's Cap is notably different—it doesn't sting! This distinctive trait makes it an appealing choice for those seeking a low maintenance cactus but prefer a gentler touch.

May your Astrophytum bring starry joy to your space!

Fun Fact: Given its slow growth, larger specimens of the Bishop's Cap cactus are often considered collectible items, adding an additional layer of fascination to these plants.
