I bought 2 pairs of 8” and a pair of 10” blue pots.  The pots  taper so the circumference at the bottom is 2” less than the rim which is fine for my plants because they like cozy roots.  They are a beautiful blue colors. The shade of blue varies quite a bit from one pot to the next.   They are heavy and that is exactly what I wanted to stabilize my tall, lanky cane begonias.  The ceramic glaze etched around the rim as a result of our hard water.  I’ll post again if the etching becomes a bigger problem.
