No... Some sort of ceramic but feels like it may have a little resin in it. It's really odd. I got it cheap and drilled a good sized drainage hole in it. I usually have to drill holes in about 80% of the pots I get.
Always looking for interesting plants for pollinators and food! Bonus points for highly, and pleasantly scented plants.
