Comment also on Buttercup Burgess. All mine are round box shaped and not acorn shaped.

Grew poorly here until I was finally able to save seed. From own seed it is growing much better in our cool climate in Britain. Variety seems to adapt.

Flavour and texture of this squash are wonderful and it keeps well too..

Comments pertain to the Burgess strain of this squash. Good producer with rampant vines. This squash averages 4-5 lbs and is a true acorn shape. It has a blossom end protrusion that makes it look very much like a giant white oak acorn in the husk. Flavor is outstanding. It is small enough to split in half and bake, yet large enough to use for pies and puddings.
