Finding a storage squash that will produce in our little corner of Alaska, in the hills above Anchorage (830 ft.), has involved years of mostly failed trials of the hardiest and shortest season storage squash. The time required for significant spring warming of even raised beds can slow the start of growth and even protection with row cover and starting indoors is not
enough to allow ripe fruit production. With the changing climate, there is more heat and drought in the summer but volatility seems greater with high chance of early frost. Short season storage squash can be grown in some of the optimal microclimates in our fair state, but that would not include our garden.
After years of block-headed failure, we tried Nantucket long pie pumpkin (C. pepo). This is an old variety that was reported as far back as 1832 that is very poorly suited to commercial cultivation for the same reason it is outstanding for the home gardener growing “on the edge”. Long pie is very aggressive, even in cool soil. It produces secondary
roots, and the vines push aside anything that grows in its way such as the weeds I forget to pull.
The reason we tried long pie is that it is harvested green with only a small patch of orange and slowly ripens over many months in the house during winter. Usually, this ripening varies from fruit to fruit and spreads out the “harvest” often till March. This would be the bane of the commercial grower but is perfect for how we eat and greatly extends the harvest. It has outstanding taste and texture that is the equal of many winter squash. The fruit range from 5-10 lbs, making them a convenient size for use. We are still working on cultivation practices that optimize production but it looks like we can obtain a yield of 1.5-2 pounds of pumpkin/square foot. Early pollination failure probably is most limiting of yield at present.
The fixation error of focusing on a short season variety provided another humbling lesson. When what we needed was a plant that grows and is used in a different manner. This is relevant to only a small segment of the
permie community, but for some other folks
gardening at the edge this could be a useful variety.
