Be cautious with this grass. It can self-sow aggressively in some areas. I've just planted it this year, so don't know how it will behave in my area.

Rating this negative for self sowing and invasive traits. It has taken hold along the shoulders of a local two lane highway, well away from any initial plantings. If you let the seed heads dry, the seeds can sprout and seedlings are very hard to pull. Beware of handling the dry seedheads, as the seeds are very sharp, and become stuck in your socks and gloves, giving painful pokes or hours of picking them out of the fabric.

I have clumps of it, for about 20 years. It does grow next to a maple tree making a nice flowing grass clump. I manage them by cutting off all seedheads before they dry and shed.

I have never found this cultivar to be beautiful and I don't know why it is grown at all. It self-sows like crazy and is aggressive in the garden by seed. It is not supposed to come true from seed. Fortunately, it is not nearly as popular as a few other cultivars and I don't see it very much.
