I grew butternut pumpkins, thirty years ago & had a few in march, but they were dry or less wet.
Yours look like you picked them off the vine & cut them up.
south anna is a cross between waltham butternut and seminole pumpkin. they crossed this in 2011 and then stabilized it into a 'new heirloom' they done this for seminoles disease resistance.
it was very moist and it stained my hands from color it is.

Latin Name: Cucurbita moschata
Days to Maturity: 110
Description:
High quality downy mildew resistant butternut squash bred for the South. We developed South Anna from a cross between Seminole Pumpkin and Waltham Butternut, and have been selecting for nine years for downy mildew resistance, productivity, flavor, brix, dry matter content, keeping quality, and general butternut shape. Exterior color is a deeper tan than most butternuts. The majority of fruits are 2-4 pounds, though they can range from 1-5 pounds.
South Anna will avoid the crop failure that can occur in years when downy mildew comes early, and provide a better quality harvest in years with average DM pressure. The healthier foliage leads to sweeter, riper fruits of a rich tan color. When used as a late planting, South Anna grows strong until frost, allowing for later harvests that will keep better into the winter and spring. Because this variety is somewhat indeterminate, we often make two harvest passes, separated by a few weeks. Strong, vigorous, fully vining plants.
South Anna is an Open Source Seed Initiative (OSSI) variety. OSSI is a movement to help protect seed from corporate monopolization. Read more at
