Overview

Royal Ace PM (listed as Acorn Squash 'Royal Ace') is an acorn squash bred to stand up to powdery mildew, which can wipe out an acorn crop. It carries intermediate resistance and produces big yields of uniform, attractive dark green fruit whose color holds in storage and whose flesh quality rates high.
