If anyone is reading this for them self to plant, just got off phone with Turner Seed. They said that I do not want peredovic sunflower. The guy at Turner said that peredovic seed mature in 60 days I think. He said if you plant them in the time frame they will be done and gone by June. He recommended using native but I am past the plant time for them. His second recommendation is Black Oil. He said if I plant them next few weeks they will be mature end July middle August.
Guy at Turner said Peredovic at use to feed dove but the seed will be gone by September.
Also if anyone need them around Garland / Dallas area Roach Feed and Seed has Black oil sunflower.
90 to 100 day maturity on Perodovik, they are a black oil sunflower seed, and you are correct, if you plant them april 15 they will be mature between july 15 and july 25, that would be 90 to 100 days. So you need to plant them may 1-15. Maybe you being further south and having more light matures them faster, but all Perodovik we've ever planted was 90 to 100 days depending on sun and rain. We plant them by may 15 and begin bushhogging strips middle of august.
