Are pine and poplar too soft for flooring?
Both can be good choices for flooring depending on your tastes and needs. There are White Pine floors still in use today in New England that are over 300 years old. They do show the nicks and dings of age, but this just adds to their character, history, and patina. Pine and Poplar are by no means as hard as Oak, but the dents occurred during normal use as flooring will in no way shorten the lifespan of the floor.
