Squash
Cucurbita pepo
Botanical family: Cucurbitaceae
A trailing cucurbit grown for its flesh (butternut, musquée, spaghetti…). Sow in pots in the warmth or in place after the frosts, on a mound or in a well-mulched pocket, spacing 1 to 1.5 m. Harvest at the end of the season before the frosts, hard skin and woody stalk, keeping a long stem for storage.
Full sun
Very rich, deep
Abundant
Frost-tender annual: planted out after the last frosts, its fruits are brought in before the first frost
An annual killed by frost in your zone
The same plant bears male and female flowers; insects, mainly bees, carry pollen from one to the other
One plant is enough for a crop
Role in permaculture
The ground cover of the Three Sisters: its large leaves keep the soil cool and hold weeds back.
Good companions
Fix nitrogen from the air (legumes)
Attract pollinators and beneficial insects
Trap plants (variable effect, need watching)
Traditional companion planting (benefit not demonstrated)
Poor companions
Traditional avoidance (antagonism not demonstrated)
Insects attracted or useful

Family behaviour: Cucurbitaceae
In general, Cucurbitaceae are trailing and hungry for organic matter: they need water, warmth and a compost-rich soil. Their large leaves cover the soil and limit evaporation, the role they play in the Three Sisters guild (maize + bean + squash).

In the Three Sisters farming system, the squash is called the 'youngest sister'. Its own contribution is distinct from that of maize and bean: its broad leaves form a living mat at ground level, shade it, retain moisture in it, and smother weeds, while its prickly stems keep deer and raccoons at a distance. Grown together, the three plants are called 'those who make us live' (the Sustainers of Life): each thrives only through the care it takes of the other two, the squash protects the soil on which maize and bean depend.

Agricultural and cultural knowledge shared publicly by Haudenosaunee educators (non-ceremonial, not secret). It is attributed here to named nations, never merged into a generic 'Native American folklore': the Three Sisters motif belongs to specific peoples. Kimmerer, who conveys it in a popular book, is Potawatomi and not Haudenosaunee, the teaching, though, is Haudenosaunee.
