I live near Towson.
I would never, never, never , plant any sedge on my property.
I live to keep it off, which can be a pain.
If you can give me the address of the church I will even go to get you some pictures.

Haha, wish I knew--the chapter doesn't name the church, unfortunately.

But see, grass won't grow in some places, I have a shady property. Under some of my trees my choice is either bare soil/mulch or something non-grass. Baltimore sedge likes the shade, unlike grass -- therefore my interest in trying it out. Green sedge seems preferable to brown mud. Another option is to plant a groundcover, but not much will grow under trees with a heavy shade, and I'm looking for other options besides liriope and pachysandra terminalis. Christmas ferns would grow there, and I planted some a couple years ago -- but the scourge of the ignorant lawn guys who don't know squat weed-whacked them out of existence.

What's your grudge against sedge? I have some very handsome ornamental ones. Not suitable as a grass substitutes, these ones, however.
