  1. Star of this season

    Just like Grace says, why grow butternut when you can grow these. They taste similar to butternut, but mature and ripen much more quickly, without suck a thick skin. If you take the time to trim/prune them properly, then around 3 squash from each plant is what you'd expect. They look like slightly smaller pumpkins. Roasting them is the way to go, 45 mins or so and they're perfect. Will definitely grow again next year.

  2. So tasty!

    Why grow butternut when you could grow these? They are very tasty and the flesh is a lovely orange colour which looks great in soup. They are fantastic roasted and the skin is thin and good to eat too, which makes them very easy to prepare. I think I got 10 from 3 plants and still have one looking healthy in store at the end of January.
