Green Hubbard squash and Blue Hubbard as well, holds up great after it is harvested. Even 2 months after the harvest, IN THE SUN, the seeds matured great and the shell held its firmness. A few seeds were sprouted inside the squash. I made a puree out of the cooked meat and WOW is it amazing in breads. I have the ULTIMATE RECIPE for squash raisin bread if you want it.

I have many seeds. Check my profile on the have list and I will be glad to trade or sell some.

This is a large Hubbard with a dark green shell color. This is the most notable difference between it and the Blue Hubbard which has a bluish gray shell. These things grow to 15 - 20 pounds so are most suitable for pies or other processed dishes, Vines take up a lot of space. This is one cultivar that puts down roots at every node so the infamous squash vine borer can be held at bay by burying the vine at each node. Probably the best keeper of the winter squashes and one the better flavored. Shell is extremely hard and requires effort to open.
