St. Charles County Missouri

Expert Response

This plant looks like Euphorbia trigona, African Milk Tree.  I know it looks like a cactus, but it's not. Cacti don't have leaves!  The milky sap is toxic if eaten and can be very irritating to the skin and eyes, so please take caution.  In Missouri, you'd be growing this as a houseplant, so be sure to give it lots of medium light, and don't let the temps get lower than 50F. Water until it drains from the bottom of the pot, and don't water it again until the first couple inches of soil are dry.  Never let the pot sit in water!.
