Gymnocalycium platense is a small, usually unbranched, cactus species, depressed, half-hidden in the earth. It will flower when 3-5 cm in diameter. The flowers with long floral tube, open wide in sunlight, & are commonly white with a reddish reddish throat & a hint of dark shading at the tips of the tepals. This is a delightful plant & well worth growing. All seeds are fresh of this season & 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 Gymnocalycium Platense | Britton & Rose | 15 Seeds
