Europe and North America both depended on flax for plant-based cloth until the 19th century, when cotton overtook flax as the most common plant for making rag-based paper. Flax is grown on the Canadian prairies for linseed oil, which is used as a drying oil in paints and varnishes and in products such as linoleum and printing inks.
The earliest cultivated plant in North America is the bottle gourd, remains of which have been excavated at Little Salt Spring, Florida dating to 8000 BCE. [7] Squash (Cucurbita pepo var. ozarkana) is considered to be one of the first domesticated plants in the Eastern Woodlands, having been found in the region about 5000 BCE, though possibly not domesticated in the region until about 1000 BCE.
It is a slender herbaceous plant growing to 80 centimetres (31 + 1 ⁄ 2 inches) tall, with spirally arranged narrow lanceolate leaves 1–3 cm (1 ⁄ 2 – 1 + 1 ⁄ 4 in) long. The flowers are pale blue or lavender to white, often veined in darker blue, with five petals 1–1.5 cm long and in varying length styles.
A trial scheme is reviving the growing of flax, which was a staple of Scottish farming 100 years ago.
Northern highbush blueberry. A number of popular and commercially important food plants are native to the Americas.Some are endemic, meaning they occur naturally only in the Americas and nowhere else, while others occur naturally both in the Americas and on other continents as well.
Before the arrival of Europeans in North America, the continent supported a diverse range of indigenous cultures. While some populations were primarily hunter-gatherers, other populations relied on agriculture. Native Americans farmed domesticated crops in the Eastern Woodlands, the Great Plains, and the American Southwest.
In 1988, the Israeli botanist Daniel Zohary and the German botanist Maria Hopf formulated their founder crops hypothesis. They proposed that eight plant species were domesticated by early Neolithic farming communities in Southwest Asia (Fertile Crescent) and went on to form the basis of agricultural economies across much of Eurasia, including Southwest Asia, South Asia, Europe, and North ...
It is said to have arrived in the United States in shipments of flax seeds to South Dakota, perhaps about 1870. [8] It now is a noxious weed throughout North America, dominating disturbed habitats such as roadsides, cultivated fields, eroded slopes, and arid regions with sparse vegetation.
