You certainly could. If you are buying Morning Glories in packets from the store, they will germ very easy. I think that the biggest problem with germing ethno seeds is that many aren't viable to begin with. Especially those meant for consumption. Start with a good vendor.

Yep.  Morning glories germ very easy, HBWR too but some vendors sell old unviable seed.  Psychotria germinates very easy if fresh, but very slow and poorly if old.  I have no experience germinating Calea.

Vendors are notoriously poor sources of viable seeds.  Better to look for individuals who grow these plants themselves.  Or non-ethno-vendor seed sellers.  Usually fresher seeds, better ID's, and more reasonable expectations of compensation.

As for Gibberelic acid, it's hit and miss.  Need the right PPM concentration and some luck.  You use the wrong concentration or the seeds didn't need the GA, and it can cause bolting and subsequent dieoff, inhibit germination altogether, or have no effect.  It's a tool with some use, not a panacea.  Best just to get good seed.
