When is the end of the Israeli harvest for sunflower seeds for export to the USA?

Question

While sunflowers seem to be summer crops requiring warmth and irrigation, I have found at least one site offering fresh sunflowers exported from Israel even now in late January. Are sunflower seeds harvested all year long? If not, when did the havest season end?

Answer 1

Well, they just have them in bins, that's why they can offer them all year around, just like any other country in the world.

If you storage sunflower with less than 11% of moisture, seeds are perfectly fine for a long time.

Answer 2

The Negev Desert in Southern Israel stays warm in the wintertime, with a high as much as 15 to 20 degrees Celsius (59-68 degrees F) or sometimes higher.
