Squared Circle Star Cactus

The Astrophytum asterias is considered "Endangered," and is on the World Conservation Union's Red List of Threatened Plants. It is native from South Texas to North Mexico.


They have become endangered in the wild due to over-collection, herbicides, and urban development.


This Star Cactus was seen at the National Botanic Garden in Washington DC.
