blue haven grass
Does Blue Haven grass self-seed? We currently have native bluestem planted on the edge of a rain garden. We have a problem with it self-seeding into an adjoining area of lawn. Does Blue Haven have this same characteristic? Does it maintain its upright position? Where can it be purchased if we would want to plant it? Thanks for your help!

The grass you are looking for is Blue Heaven. That is a cultivar of the native species you currently have. Blue Heaven is not known to self-seed but like all ornamental grasses, the clump will gradually get larger over the years. You should be able to find Blue Heaven at full service garden centers starting in early/mid-summer. It will not be available early in the spring as it is grown outdoors and has to come up. This link will give you some more information on the cultivar. https://www.waltersgardens.com/variety.php?ID=SCHBH
