Question: sunflowers !!

A curiosity: are sunflowers considered wildflowers?

Answer: sunflowers !!

Dear Lia,
in general, wildflowers are those that develop without human help, without the need to be sown, and are therefore by definition wild flowers; sunflowers, those almost three meters high that are grown in the fields to get oil and feed, well, rather we could call them industrial flowers rather than wild flowers. Clear that these are hybrids, given that now the sunflower has been cultivated for hundreds of years, all originating from North America.
It is true that, apart from helianthus annuus (the classic sunflower, the huge one), all the other species of helianthus (or sunflower) are practically not grown in Italy. At one time the cultivation of helianthus tuberosus was also attempted in Europe, which is nowadays only cultivated in very small areas. This attempt at introduction, however, allowed the plant to grow wild, even in our peninsula; therefore, even if it is a "foreign" dish, we can safely say that there are sunflowers that can be considered wildflowers, as they grow spontaneously in non-cultivated areas or along roadsides; after all, sunflowers are relatives of our local daisies, and those are wildflowers in all respects.
So if you want a sunflower-type field flower, you will have to consider the sunflower species that resemble large yellow daisies, generally with a diameter of about 6-8 cm, which develop on large, slightly ramified plants, which can reach two meters of height. In Italy these sunflowers are known more for their roots than for their flowers, they are topinambur, and are hardly found in cultivation.
These are the field sunflowers, in practice; but their appearance is decidedly very different from that of cultivated sunflowers.
Then it depends on how you see the wildflowers: if among the wildflowers consider also the wheat (it often happens that in the bunches of "wildflowers" there are also some ears; in this case also the sunflowers are wildflowers.
