Same amount. I bought one plant years ago circa 2003/4 off of an eBay vendor. It started out like the normal one. I only know of one other person who bought the same plant at the same time from the same eBay seller, a fellow old time collector of aroids who lives in Hawaii. Hers is normal and has never exhibited this trait. If other people have a plant from the same seller that still exists (and there must be a few, I think there were maybe 5-6 plants sold) they do not appear to be in the online plant community at large. This plant offsets I wouldn't say frequently but easily, and I have divided it several times over the years. I first saw this mutation several years ago and separated the offset off immediately to grow out separately.It was a stable trait, and all offsets produced by this first one have been high silver. Further, I pollinated some other anthuriums to hybridize them (forgetii, Mehani, magnificum) and the children of the FORGETII so far also can carry this trait. (photos 3,4) (I put the pollen from the silver plant onto the forgetii, the forgetii made the seeds...photos 1,2). Some years ago, an anthurium called Selby Silver came around, it was a plant that seemed to be a spontaneous mutation/hybrid of a crystallinum that was found in the collections of the Marie Selby Gardens. It resembles mine superficially but there are differences.
