Squash (Pumpkin)

Squash (Pumpkin)

Family: Cucurbitaceae
Genus: Cucurbita
Species: C. maxima, C. moschata


The squash (Cucurbita spp.), also known as pumpkin, is an annual herbaceous plant belonging to the Cucurbitaceae family.
The species is native to central/south America and is currently grown almost all over the world.
The varieties most commonly cultivated belong to two species: Cucurbita maxima Duch. and Cucurbita moschata Duch.
The plants grow in spring and summer, all the phases of cultivation occur within 6 months, from sowing the seeds to harvesting the fruit.  
This species should be planted in full sunlight and prefers soils rich in organic matter; it needs to be watered well while the plant is growing, but when the fruits are growing it prefers a dry climate.
In nature squash plants grow as climbers which, in the absence of vertical wall or supports, can seem to be creepers.
They have a fascicled root system which grows to a depth of around one metre, however the majority of the roots are found in the layers of soil near the surface.
The stem is very sturdy; it grows to a length of several metres (from 2 to over 10) and has tendrils, which can anchor the plant to vertical supports.
The leaves grow to a considerable size and are attached to the stem by long petioles. The shape of the leaves varies according to the variety, they are usually heart-shaped or palmate with lobes that are not very pronounced.
The flowers are bright yellow and are supported on fairly long thick peduncles.
The squash is a fruit with characteristics that vary according to the specific variety. The fruit can be round, turban-shaped, elongated or flat and can vary in colour from yellowy orange to green. The skin can be smooth or wrinkled, and can be “warty” or have ribs and stripes.
The flesh is yellow/orange and almost completely fills the fruit; the cavity inside contains filaments that bear the seeds.
In the kitchen the flesh is widely used, it can be eaten, cooked, on its own or as in ingredient in more complex dishes. You can also eat the seeds (roasted) as well as the flowers (fried).
