I love Mammillaria cuties :D These little babes are growing in one of the Smith Building greenhouses at Boyce Thompson Arboretum. The first is Mammillaria tesopacensis. The second didn’t have a label I noticed!
Expect many more pictures from my day trip down south! I took ~500…Boyce is my fave arb/garden in AZ.
Mammillaria pulmosa, feather cactus (Cactaceae) named for those adorable feathery spines. Native to northeastern Mexico. Has gained the Royal Horticultural Society Award of Garden Merit. Basically, they’re easy to cultivate in greenhouses.
