80-90 days.  This unusual tan acorn squash is totally under-rated!  Vines bear abundantly and all fruits mature in 90 days or less, perfect for our short season climate.  Flesh is tan and like the name suggests, smooth, sweet, complex, and even chestnut-like.  So flavorful, we like to steam it and eat it plain!  Originally from Thelma Sanders of Kirksville, Missouri, the seed was given from Evert Pettit to Sue and Tom Knoche, Ohio squash collectors. Thelma described this good keeper as ‘better than sweet potatoes.’

Plant 1-2" deep in small mounds 24" apart. Winter squash are heavy feeders so provide fertility initially, then every few weeks through the season.  Harvest before the first frost, as even a slight frost will damage the flesh and make the squash unstorable.  Allow to cure in a sunny, frost free location for 2-3 weeks.  This curing process seals the pores of the squash skin for storage and improves flavor.
