I've been looking for local sources and found two options. One is the the local "fish club" where people apparently have spare plant cuttings that they might be selling or giving away.
I'm more hopeful about my second option... I was searching eBay for domestic plant options by using their "Distance" option for sorting. Well, I kept finding this person who was like 6 miles from me. I finally got up the courage to use the "Ask a question" to introduce myself and we've been communicating by email. Turns out this person has a *huge* fish room with over 100 tanks! In addition to having plants she also breeds guppies, plattys, mollies and BETTAS!
She has some amazing fish. Apparently she often "rehomes" her breeding pairs, which are sometimes AquaBid imports, after they've given her some spawns. Oh the possibilities!
Anyway, those are some options. :)
