I just had a bad experience with an ornamental grass that made so many babies that I had a hard time keeping up. I've removed them and wanted to know about purple fountain grass. Does it overly propagate? What other grasses would you recommend? How do I control over-population of grasses. Do I cut the plumes back? Thanks.

While it really depends on the type of grass you have, removing plumes as they develop does often help to prevent seeding and subsequent spreading. As for the fountain grass, you should not have any of these issues. It is not considered invasive at all.
