Chamaecereus silvestrii has long stems about 1 cm (0.4 in) across. Orange flowers up to 4 cm (1.6 in) wide appear in late spring. In cultivation, Ch. silvestrii is hardy to temperatures as low as −7 °C (19 °F) if kept dry.[2]
Ch. silvestrii was first collected and described in 1896 as Cereus silvestrii by Italian-Argentinian botanist Carlo Luigi Spegazzini in the mountains between the provinces of Tucuman and Salta, Argentina.[3] However, subsequent expeditions to the area failed to find the species Spegazzini had collected and it is unknown whether the species has gone extinct since the initial collection.[4]
This plant is a recipient of the Royal Horticultural Society's Award of Garden Merit.[5]
