A few months ago at HD, I noticed all the poplar was very green in color. Today I purchsed some that allmost looked like walnut. Thought it was a new shipment, But maybe it just turned. My question is, will it change color after it is finished? Whether purchased white, green, or brown.jerrymayfield said:The greenish streaks often found in poplar will turn to brown in time,which will add to the proplem.
