Blue Sedge, Heath Sedge 'Blue Zinger'

This sedge was a huge mistake for me. It was well behaved for several years before rampaging wherever I planted it. It spreads seemingly ...Read Moreindefinitely.
It gets quite large and flops over onto itself. The foliage underneath gets ragged and literally rots underneath it.
It is a nightmare to dig out because the slightest bit of root left sprouts up. I have been digging it out and it has been awful.
It is also a haven for rodents. Mice and voles love to hide under it. This has not so great implications for tick populations.
It seems to harbor disease that affects evergreen shrubs and trees. It was growing beneath some arborvitae and Chamaecyparis and the foliage near the blue sedge was developing problems. It is one of the reasons I decided to dig it out.
It is now documented as being invasive in the Northeast.
All in all this just an enraging thug of a plant that does not play well with others. It will quickly outgrow its space, needs to be cut annually to prevent foliage issues and to look good. Defeats the purpose of a sedge ground cover.
I truly hate this plant I regret planting it.

I bought two of these plants from a large nursery in the Twin Cities a few years ago. Within a year or so, I was able to divide the two p...Read Morelants into 6 plants.

I have seen this plant thrive in mostly shade (medium moisture) and also mostly sun. It does not seem invasive here in Zone 4b. It is spreading out, but not at an alarming pace.

I'm going to try moving some of it to a dry shade spot in my front yard (under a large tree) so see if it can expand even in a difficult spot.

Here in Minnesota, the plant even manages to be an evergreen (when it's not covered in snow). It looks tidy and attractive for the entire growing season here.

A pretty plant; however, I had it in full sun and it spread a lot - about 6X - in less than a year, and was impossible to pull out! I had...Read More to dig it out with a large shovel. If I had known how agressive it really was to begin with, I may not have acquired it, as I do not want to devote that much room to it. It would probably be great as a solid groundcover of a large area, though.

This selection of C. flacca is exceptionally silvery blue and forms elegant fountaining clumps. It is quite vigorous in moist soils and h...Read Moreas spread to form a soft groundcover between our hostas and other tall shade perennials and shrubs. We also have it in a dryer location where it hasn't expanded in two years, but it still looks great! I also have it in a container with Eupatorium 'Chocolate', Painted Fern and Frosted Violet Heuchera. Stunning!
