I plant this squash every year--it is by far my favorite winter squash. It has excellent flavor, is extremely productive, and keeps through the winter. Give it lots of room because it will take over the rest of your garden.

My favorite winter squash so far. Very productive (24 from 4 plants in 2006 in Wisconsin) and delicious. The most productive squash I have grown to date, as well as the tastiest. Japanese F1 hybrid (maxima x moschata), 91 days. It is round, somewhat bumpy, and ridged, with very dark green-black skin. Flesh is a deep yellow-orange. Extremely nutty and sweet tasting, with flavor similar to a kabocha. Flesh is firm. Has been very resistant to vine borers and squash bugs for me. Was also a very good keeper through the winter. Requires a pollinator so you have to grow something else too - too bad!
