It came out of a deliberate U.S. breeding project that crossed a Central American highland squash with Waltham Butternut, then selected the result over several generations for downy mildew resistance and for the ability to keep setting fruit through weather that swings hard. That is exactly the problem a Kansas summer hands you, which is why it earned a spot in this catalog. The variety is named in honor of climate activist Xiye Bastida, and it carries the Open Source Seed Initiative pledge, meaning it stays free for anyone to grow, save, and breed from. The fruit is a classic butternut silhouette with tan skin and rich, deep orange flesh that gets sweeter in storage. It handles the brutal mid-summer stretch without losing fruit set, and cured squash will hold in a cool dry room for months. Xiye is Cucurbita moschata , a species often chosen for vine borer resistance. Its dense stems can make damage less likely, but pest damage is still possible. Check plants for eggs, entry holes, sawdust-like frass and wilting, and continue scouting for squash bugs.
