This is Coryphantha robustispina aka #pimapineapplecactus grown from seed I collected near the Pima and Santa Cruz county line, Arizona. #coryphantha #coryphanthascheeri #coryphantharobustispina #cactiarecool #cactusmania #cactusaddict #kaktus #lifesuccs

Coryphantha robustispina budding up for the first time! I collected seed from Amado, Arizona a while back, and it seems to have gotten around. #pimapineapplecactus #coryphantha #coryphantharobustispina #coryphanthascheeri #grownfromseed #cactusflower #cactusmania #cactusgarden #cactusmagazine #cactusworld # #cacti #kaktus

Finally got a flower today on this Coryphantha robustispina (aka Coryphantha sheeri var. robustispina, Pima pineapple cactus, stout needle mulee). It opened the same day as my Coryphantha scheeri from #bandbcactusfarm, which is probably C. scheeri var. valida. #coryphantha #coryphantharobustispina #coryphanthascheeri #thetwocorys #grownfromseed #cactusflower #cactusmania #cactusgarden #cactusmagazine #cactusworld # #cacti #kaktus
