Crinum thaianum

  It should come as no surprise that common names are inconsistent. There is an actual onion sold as an aquatic plant (like many "aquatic" plants - it's really a marginal plant that can handle periods of submersion) - so that's likely what you saw. It merely lingers in an aqaurium - I've never seen it do more than slowly decline when kept submerged. $2.50 for that sounds about right - I've never seen C. thaianum that cheap. $25 for calimistratum sounds about right, tho. Expensive, but they do grow into superb aquarium specimens.

My query about Crinum thaianum elicited some doubts, but the sales guy did recognize the name crinum and said that he thought they had C. calamistratum. When I offered the name "on\ion plants", he brightened up and took me over to see them. They were being sold as "octopus plants" - Alani's description of the 12 foot leaves immediately came to mind. Whatever they are, they were being sold for about $2.50 each. The bulbs reminded me of those of Acis autumnalis - maybe a bit bigger -  and so did the chive-like foliage (it was proportionally coarser than that of the Acis and not flat). Maybe they are onion plants after all!

What I saw was at first glance  a dead ringer for the fern known as Athyrium filix-femina 'Frizelliae'. - Dave's description of it as highly crenulated was spot-on. I was greatly tempted by this one, but the $25 price tag was more than wanted to spend.
