question about a type of sunflower

Выращивается с 1960 года. Это семена от известного фермера из Австрии - Зеппа Хольцера. Подсолнухи вырастают до 5-ти метров в высоту и до 50 см. в диаметре. Семена можно употреблять в свежем виде, получать из них масло и жмых. Листья, стебли и корни можно использовать в лекарственных целях. Можно выращивать в оградительных целях, как живой забор.

I will try to translate this. "It is grown since the  1960's. These are seed from the famous Austrian farmer -Sepp Holzer. the sunflowers grow up to 5 m in height and 50 cm in diameter.
The seeds can be consumed raw or they can be used for oil production. The leaves, stem and root may be used for medicinal purposes. This plant can be grown as a hedge."

unquote.

I found this plant in a Russian website and I would like to ask if anyone has some information about it. Looks interesting. I would definitely like to know more about this
variety of sunflower.

That just about has to be a multi branching variety of "Russian Giant" judging by the stem length.

The sunflower originated in North America and was first hybridized by the First Peoples, when the invaders landed they took back some examples and the flower ended up in Russia, where it was exploited for the seed oil.
This brought about a surge in production in Russia and Europe in general while at the same time the sunflower almost disappeared from the soils it had sprung from.
It was in the 1800's that the venerable sunflower made its way back to native soil.

Since then it has become both a seed oil plant and a flower for home use as decoration along with the roasted seeds as human food, it is also animal food.

I have not been able to locate the name of any tall, branching variety listed anywhere I have searched.
But I am sure that variety was developed, most likely in Russia, as a seed oil plant.
