Another example for you to ponder. Epidendrum ciliare is one of my top 10 favorites out of my 300 orchids. It was one of three on the show table at our society meeting last week. All were mature, well grown and flowered plants. one had 3-4" long leaves and inflorescences, another's were 6" and mine are at least a foot long. It can't really be culture in our case, I don't believe, as we all grow outdoors which leaves genetics.
