We're always looking for ways to take fall color in gardens to the next level. The trees take care of the oranges, reds, and yellows, but what about the more subtle, awe-invoking colors link pink? Undaunted® Ruby Muhly Grass (Muhlenbergia reverchonii 'PUND01S') is exactly what the fall garden is missing.

Before its fall show though, Undaunted gives quite the spring and summer performance as an accent plant in your garden. Planted in clumps of three for maximum effect, this grass grows lovely green foliage.

You'll find that this grass tends to grow in a nice, compact, rounded formation. This creates a pleasing half-circle appearance that's sure to delight and invites a closer look.

Undaunted's genus, Muhlenbergia, honors amateur botanist Lutheran paster Gotthilf Henry Ernest Muhlenberg (1753-1815) who was quite distinguished in the field.

This grass is sometimes referred to as seep muhly but, personally, we like its official name as it isn't intimidated by colder weather in the slightest. You'll find this Muhly grass is hardier than many others in the genus.

As the air turns crisp and our thoughts turn to apple cider and pumpkin patches, Undaunted Ruby Muhly Grass gets to work setting up its own fall attraction. Finely textured red seed heads will rise above the foliage to make a stunning pink haze!

This native grass keeps its color through fall and into winter, giving your garden a burst of color even as other plants fade into dormancy.

Just imagine how pretty the ornamental grass would look surrounded by a fresh dusting of pure white snow!

As an added bonus, Undaunted Ruby Muhly Grass seems to be deer resistant for the most part. So you won't have to worry about waking up to find the munch markings of a hungry deer.

The unique pink seed heads and its impressive cold hardy tendency are just a couple of reasons to add Undaunted Ruby Muhly Grass to your garden. Order one or perhaps a few to accent your outdoor projects with today!

How to Use Undaunted Ruby Muhly Grass in the Landscape

The ways to use ornamental grass are endless! Add in the fact that it'll give fascinating fall color is just icing on the cake!

The most obvious way to use Undaunted is as an accent plant in your perennial flower beds. Its interesting texture will elevate the elegance of the perennials around it without overpowering the pops of color.

Not to mention it'll get to work producing color just as the rest of the bed is hunkering down for the colder months. No need to share the spotlight!

Plant in a line around the edges of your beds or property to create a pretty border. This grass is especially good for edging because of its compact growing habit.

Do you have a bench or seating area in your garden? Plant a clump on either side to give added interest during all seasons!

For the best effect, you'll want to consider planting in clumps of two or three in the landscape. You won't be sorry! As the plumes that evoke thoughts of autumn embers bloom, grab a picnic blanket and use Undaunted as a backdrop for fall family pictures!

Add this grass to your container growing regimen as the thriller in the thriller-spiller combo.

If you have a larger space to work with, use this Muhly grass as a mass planting. Fields of pink seed heads would be a sight to behold for sure!

#ProPlantTips for Care

This Plant Select introduction from Colorado is just as low maintenance as you'd expect from a hardy native grass.

To keep Undaunted happy, all you need to do is pick a place to plant it where it'll get full sun and in well drained soils.

That being said, this grass can tolerate drought relatively well as well as soggy soil for short periods of time. It's a real plant it and forget it grass!

Follow those few instructions and you'll have this long lived grass for years to come. You can always consider adding a layer of mulch around its base, however, that's hardly necessary to keep Undaunted happy as a clam (well, grass).

You'd be hard-pressed to find an easier to take care of plant with such a power fall presence than Undaunted Ruby Muhly Grass. Order one for your garden from our expert growers at Nature Hills Nursery today!
