The correct answer is - Flax could not be raised at all in England;
The fact that the flax was not cultivated in England had no influence whatsoever on the rise and development of the textile industry in the country.
The flax is hard to produce on a large scale in England, though it can grow, just with lesser quality, but the English were not using it for textile material, but instead they used primarily the wool from the large number of herds of sheep.
The wool was of high quality, it has excellent properties, and it was very popular as a material, especially because of its good properties for thermal isolation, so the textile industry flourished.
