I have six of these planted beneath a long bed of 3 river birch. They definitely do flop toward the end of the season, but the bigger problem is self-seeding. The first three years, no problem, but this year, I have tiny volunteer grasses EVERYWHERE.

You can try to deadhead, but mine produce tons of seed heads so it's tough to get them all in time. Plus, without the seed heads, the winter interest is minimal.

Consider carefully--I wouldn't plant this again.

I love this grass until it finally sprouts up past 4'. Once it hits that mark it flops over in my garden. What I have read is that it does not like fertile rich soil or to be watered. At this point I plan on moving it outside the compost enriched beds.
