Last year, someone in a yahoo pepperomia group thought it was a crinum,
too, but I hadn't been convinced. However, last night I emailed a
website (Old House Gardens) that sells crinums and this is what they
"Thanks for your inquiry! The photos finally came through and we do not
think that what you have is a crinum. A crinum is a bulb and the
foliage would come right out of the ground, there wouldn't be a trunk
or any woody part of the plant. Unfortunately, the bloom looks a little
past it's prime, so it's hard to say what you've got, but we don't
think it's a crinum."
Does anyone else have any idea?
