110 days. Cucurbita maxima Blue Hubbard Squash was introduced in 1909 as Symmes Blue Hubbard Squash by James J. H. Gregory & Son seed company. It was first listed in their 1910 Retail Catalogue. JJH said of the Blue Hubbard, “Thick meated, fine-grained, dry and very sweet; close your eyes while eating and you would think you were eating cake.” Hubbard Blue Squash is a soft grey-green to deep green on the outside, the sweet orange flesh is an amazing keeper and great for pies! If you’d like a winter treat, bake one of these with butter salt/ pepper and serve in slices. Fruits can weigh up to 15 lbs! Blue Hubbard happens to also be the favorite of cucumber beetles. Why is this important? Use it as a trap crop! Plant blue hubbard first on your gardens borders and "trap" all the cucumber beetles in their favorite squash. Hubbard Blue Squash is an excellent keeper lasting up to 5 months in a root cellar or cool closet. Contains 15 heirloom seeds
