Dyckia — 10 species

Dyckia is a genus of roughly 120 terrestrial bromeliads native mainly to central Brazil, distinguished by stiff, spine-edged leaves in rosettes ranging from silver-grey to deep burgundy — cultivars like 'Cherry Cola' and D. fosteriana are collector favourites for their drought resilience and sculptural form. They demand bright, direct light and very infrequent watering: allow soil to dry completely between sessions, as their thick leaves store moisture efficiently. Toxicity varies across species; check each specific variety before buying, and handle with gloves as the serrated leaf edges cause physical injury.
