Hello,
I'm having a terrible time identifying what plant these came from!

They are not manzanita or driftwood. They may be holdfast or a type of mushroom (though they seem too woody and fibrous to be a fungus/mushroom, in my uneducated opinion).
I purchased a box of 30 for $5-7 at a craft store a few years back, being marketed as "floral decoration". I now have a use for them and desperately need to find a supply source.
Lightweight, fibrous and woody. They appear to have been bleached or sandblasted. The stalks seem to become hollow away from the root-like area; where solid, the core is a hard, foam-like substance (it cannot be dented with a fingernail, but looks similar to the insides of some reeds/grasses). Many of the pieces are more twisted than the ones shown in the photo.
I'll certainly take a better photo/answer questions if clarification is needed anywhere - please let me know. I am really having a tough time getting these identified!
Thanks.
Update: I'm in New York, USA. I bought them at Michaels, which is a chain/nationwide store - so the stems could be from anywhere in the world (maybe safe to assume from China).
