Starke Ayres

Starke Ayres supplies vegetable, lawn and flower seeds in its headquarter country of South Africa, as well as internationally. Its origin dates back to 1870, when Charles Ayres established a nursery in Rosebank, South Africa, and in 1896 formed Starke Ayres (Pty) Ltd with Charles Starke’s local seed business. Pannar Seed took over the company in 1985, and after Corteva Agriscience (DuPont Pioneer) acquired Pannar Seed, Starke Ayres became part of the Plennegy Group. The company sees supplying subsistence farmers with seed, chemical products and fertilizers as its secondary business activity behind commercial farmers.
