Winter Squash – Burgess Buttercup



The classic, heirloom buttercup introduced by Burgess Seed and Plant Company in 1932. While we like to err on the side of offering less-common varieties over the commercial standards, we’ve made an exception for Burgess due to its dominance in our butternut trials. Striking, turban-shaped squash with thin, dark green skin and a light blue “button” on the bottom. Burgess Buttercup Squash perennially wins us over with its rich, nutty and sweet flavor.  When baked, the bright orange flesh is not as dry and flaky as a kabocha, yet not as moist as other Maxima-type squash.  3-5lbs fruits that will store for several months after harvest. Seed grown by Thompson Creek Farm.
