Anthurium cubense x pendulifolium (same cross as Big Bill)
Anthurium cubense x pendulifolium can get to enormous size! It's the same cross as famous Anthurium 'Big Bill', named after the owner of Silver Krome Gardens. All plants are seed grown so there may be some variability but given other clones of cubense x pendulifolium we have seen, these plants should all have the ability to achieve enormous proportions!
NOTE: After speaking with Bill, he now believes the mother plant of 'Big Bill' may have been an aberrant form of Anthurium plowmanii, one that is very closely related to cubense.
