Royal Knight Green Crookneck Squash

Can be eaten in both the immature and mature stages.

In its immature stage, it is medium green, tender outer skin, robust flavor.

In itís mature stage it has a dark green/black hard skin/shell that will allow you to keep it like a winter squash for a couple of months. Treat this mature squash the same way you would a winter squash when cooking.
