Thanks so much for the feed back. The prices from Santa Rosa seemed very good. Will the plants be a good size this year?

I've a catalog (Plants of the Southwest) that says Sporobolus wrightii will get to seven feet. 300 seed for $2.50. May require three years?

I forgot about S. wrightii. I have a packet of seeds from PoSW waiting to be started, too.

grammie..different varieties grow at different speeds. In general, the old rule for perennials also applies to perennial grasses;

First year they sleep.
Second year they creep.
Third year they leap.

An example is two Miscanthus varieties I got last year, M.s. 'Gracillimus' and 'Gold Bar.' I potted them up in early summer, and by the end of the growing season, the 'Gracillimus' was 2' tall, but the 'Gold Bar' had only grown 6".

Gold Bar is a little on the slow size, donn, from my experience. It is an outstanding miscanthus grass, but moves about as fast as a teenager getting up for school.

I agree, the perennial rule fits grasses for the most part, but if you provide proper conditions, an early spring planted miscanthus grass clump or pot should reach 1/3 to 1/2 size by fall, and 3/4 to full mature size the following fall, or by 3rd year at least. Conditions and weather are everything!

If you're in Chester county, take a visit over to Longwood Gardens and se their grasses coming up this spring.
