These heirloom varieties of squash are the literal fruits of my springtime obsession with Cucurbits (the gourd family – almost 1000 species of zucchini, pumpkin, watermelon, cucumber, etc).
This obsession grew thanks to Dr. Lori Shapiro who knows the coolest facts about squash! For instance, before domestication, wild gourds contained bitter toxins. Only megafauna like mammoths could ingest and disperse the seeds of these protected fruits (1). In the Americas, early hunter-gatherers used dried gourds as floats for fishing nets and to hold food and water. They also used fresh wild gourds for the medicinal properties of the bitter compounds (2). The wild gourd (Cucurbita pepo) was the first plant domesticated in the Americas, and the first agriculturalists likely grew them for their nutritious seeds rather than the bitter flesh. Thanks, Lori!
