This form has big, apricot coloured, and is very frosthardy when dry.
This form has big, oange flower and is spinier than the darwinii MK 1173. I have a soft spot for this plant, because it originally came Jan Essers, an old friend of mine. The collection number was JES 89-15.
I grow these plants in trays, so they grow into a nice clump. Eventually they will outgrow their tray.
Small joints with barbed spines. Joints will hang on our fingers.
