Gymnocalycium mesopotamicus (15 seed)

Gymnocalycium mesopotamicus is a small cactus often solitary in habitat, but freely branching in cultivation where it makes pleasing clumps.
Stem: Flattened-spherical with an umbilicate depression at the apex, dark green, 1,2-2,5 cm tall and up to 4 cm in diameter (but often more in cultivation)
Ribs: 7-9, low and obtuse, well developed or rather indistinct, rounded, with transverse grooves.
Areoles: Wide, oval-elongated, slightly sunken at the top of the tubercle.

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 )
