Ratings & Reviews
Great flavor, unbelievable keeper.
Ordered this variety last year and was very pleased. Excellent sweet nutty flavor. Was amazed at how long it keeps, just baked the last one, in April!
Very easy to grow, very prolific
Grew several plants this past season, one in a container and all were very prolific. Dozens of good sized squash from just a few plants.
Had pumpkins succumb to vine borers, these squash a few feet over were unaffected.
Tasted great! Ate them / gave them away before I could see how long they'd keep.
If you only choose one winter squash, choose this one.
If you only grow one type of winter squash, this is the one to grow. Hugely prolific (we got more than 40 from four plants!), excellent flavor, and they keep for as long as a year.
As always, a pleasure to grow in the garden and eat! They seem to fair a little better than some types with squash vine borer. I always get many, many of these to harvest. They keep making more fruit until frost kills them! They store well. We just ate the last one yesterday because I needed to plant seeds for this year! I did actually get a few that were fatter and more squat, but that was not a negative in any way! And some that tipped the scales at 6+ pounds! For best storage: harvest when stem is browning. Cut the vine, not the stem. You can trim the vine off and make them pretty once the stem has dried. Cure in eastern sun for a couple weeks. Wash in dish soap and vinegar. Dry in sun. Wipe down with an oil like olive or rapeseed. Keep in cool and dry place. Check at least every week or two and use up squash with blemishes or soft spots. NY zone 6b
Sprawling over 15ft in each direction. Each plant produced over 8 fruits each. Great for roasting. The were susceptible to squash bugs though

Had an outbreak of squash bugs this year that decimated my Delicata and Hubbard squashes, along with my yellow crookneck summer squash. They slowed down my Long Island Cheese but didn’t kill it and I’ll get one pumpkin this year, I think. These butternuts were apparently hated by the squash bugs. I would occasionally see some eggs on the leaves but it was the exception rather than the rule. These vines struggled less with powdery mildew as well, probably because they weren’t as stressed by the squash bugs. Great yields every year I’ve grown them and keep really well. Delicious flavor too!
Good for squash newbs like myself. Big delicious squash, with lovely orange flesh. Definitely growing them again.
