Thanks Gyr_Falcon. I think you are on to something. I looked up Symphoricarpos albus and it looks like it grows in places with regular moisture. This one gets no moisture other than rain, and the leaves on this one look thicker than the ones for Symphoricarpos albus. But similar enough that I put just Symphoricarpos into the usda plants database and checked out other members of the genus. Symphoricarpos occidentalis seems to be a good possibility. I guess the seeds are going to tell for sure, so I'll wait for them. In the meantime, I found the other gardenwebber's old posts and emailed her, so maybe she will email back if the email hasn't changed. Thanks!

Based on what appears to be a rosette of smaller leaves at the base I think it is a Dichanthelium sp. (which used to be in the genus Panicum). AFAIK all of the Dichantheliums are native.

You might see if there are any wholesalers who can supply smaller tubes of the Purple fountain for landscapers - even if you ask a landscaper to buy them in - if you can get cheaper pots and sacrifice some plunes by giving a good haircut, you could try dividing the clumps & could probably produce 4 times the number for planting out. In terms of native grasses, I don;t know your area, I know I find a lot of roadside grasses in my area very pleasant even though some may be weeds. Do be careful though when I say "weeds" some species can be very invasive - Qld now has a problem with the other fountain grass. I found this site which can supply small trial quantities of seed and has some good sections of notes on grasses and their uses (no commercial interest) Here is a link that might be useful: native grass seed supplier

looks like a pasture grass to me... Perhaps Poa pratensis (Kentucky bluegrass, english meadow grass, smooth meadow grass) You'll need a photo of the flower rather than the seeds if you want a good Id. Also, is it a runner grass? How often does it flower (once a year, any time in summer, straight after rain?). That fact that it has happily come up in mulch tells me that it is almost certainly a weed. I would recommend against propagating a grass you can't accurately identify - you might end up spreading something really hard to get rid off, like serrated tussock! (when I was young I carefully propagated some interesting grass I found on a friends farm - a year later I discovered it was mexican plume grass and spent 3 years getting rid of it.
