Ferocactus hamatacanthus (a.k.a. Turk's head) is a medium sized barrel cactus with spines somewhat variable in number, diameter, and position, depending on origin.

Pericarpel surface with 10-40 small, triangular scales with greenish-yellow, fringed margins. Filaments yellow to orange-yellow, anthers and pollen yellow. Stigma stigma yellow longer than stamens, with 8-14 lobes curved and twisted 4,5-6 mm long. The flowers are scented.

All seeds are fresh of this season and obtained from my personal collection.
(NOTE: cactus seeds could be sown in any season under control environment, however if you wanna go with nature then best time to sow the seeds is early spring/summer ) (check my collection at https://www.instagram.com/planetcactus)
