Winter Squash – Burgess Buttercup




The classic, heirloom buttercup introduced by Burgess Seed and Plant Co. in 1932. Striking, turban-shaped squash with thin, dark green skin and a light blue “button” on the bottom. This variety 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.
