Anthurium crystallinum is an easy growing species with beautiful veins. The foliage opens up a metallic green with yellow/red tones and slowly darkens to deep green.
Note that many A. crystallinum circulating in cultivation are "bench hybrids" with complex parentage from origins in Hawaii/Florida/Indonesia/Thailand. The crystallinum produced here are bred from our from selected stock plants from Ecuadadorian/Colombian origin that were previously distributed as crystallinum "Dark Form" from Ecuadorian nurseries. They seem much more consistent with the species type description though there's probably still work to be done to fully elucidate their exact origin.
