Are you thinking of Japanese Blood Grass, Imperata cylindrica 'Rubra' or 'Red Baron?' If so, use Google to search for those names, and you'll find several sources.

Be aware, zone 5 is at the bottom of this grass's hardiness range, and you may have to provide it with winter protection.

Imperata c. 'Red Baron' is on the noxious weed list for over 20 states, so you may want to check that first.

There are some other grasses that offer great red and burgundy coloring at various times of the year.

Panicum Shenandoah, Pennisetum Rubrum, Pennisetum Prince and Princess, Miscanthus Purpurascens are some that come to mind.

Here is a link that might be useful:

I think we've had this discussion before. Japanese blood grass, Imperata cylindrica 'Red Baron" (or less commonly 'Rubra') is a very slow to establish, slow to spread and rarely flowering (therefore seed-producing) form of cogon grass. The species IS invasive and rarely if ever seen in commerce, however I can find no evidence that has firmly concluded the cultivar 'Red Baron' produces the same aggressive behaviour and it is generally considered not to be invasive (nor is it listed on many invasive plant lists), certainly NOT in zone 5.

This grass is widely grown in my area and I've yet to encounter any reversion back to the species nor any indication of flowering/seeding or aggressive behaviour. Rather, it is an extremely slow-to-establish grass and demonstrates quite the opposite of any invasive characteristics.

I agree with your take on Red Baron's growing habits, Gardengal. It is, however, prohibited for shipment into over (I believe the number is 22) states at this time, as well as the commercial growing being prohibited in those same states. Wrong or right, it's an uphill battle arguing with the ag department.

I mention alternatives in keeping with those state's ag regulations, should wspiker happen to be in one.
