How are the heights measured?
All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.
What is a gallon container?
Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.
How does the delivery process work?
All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!
Why are some states excluded from shipping?
The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.
The Undaunted® Ruby Muhly Grass is a wonderful late-season ornamental grass that has soft, hair-like leaves and many spikes of flowers from late summer all through fall. These are dusky red-pink to ruby-red, and glow entrancingly in the fall sunlight. Add a beautiful late season lift to your garden beds, or grow it among rocks, on slopes, and in dry places around your garden. It forms a dense clump and is entirely non-invasive.
- Beautiful ruby-red flower spikes from late summer all through fall
- Graceful clump of hair-like leaves
- Clump forming, so it never spreads and takes over your beds
- Very drought resistant and ideal for xeric gardens
- More cold resistant than other varieties
Full sun and well-drained soil are needed for the Undaunted® Ruby Muhly Grass, which should not be grown in soil that is frequently moist. It is free of pests or diseases and entirely untouched by deer, and well as being extremely drought-resistant once it is established. Established clumps should be trimmed back in early spring, before new leaves begin to grow.
- Plant Hardiness Zones 5-10
- Mature Width 1.5-2
- Mature Height 1.5-2.5
- Sun Needs Full Sun
Depending on the variety, ornamental grasses are at their best twice a year – in spring and in late summer to fall. This fits with the way we divide these grasses into ‘cool season’ and ‘warm season’. Some grasses spring into growth with the first hint of warmer weather, and these are soon fresh, bright and lush, flowering early in the season. The warm season grasses wait out the uncertain spring weather, and don’t wake up until reliable hotter days are here. While the cool season grasses often look untidy and sad by summer, needing a trim and fading from interest, the warm season grasses only get better and better. They flower in late summer and fall, just when the rest of the garden is looking tired. They give a lift and a freshness that lingers on, extending the garden season, and with the Undaunted® Ruby Muhly Grass that lift is richly colored, a glowing cloud of dusky dark pink that glows in the low sun. Two or even three feet tall by then, the softness of its look hides how tough this grass is. It’s easy to be highly drought resistant and revel in dry ground when you grew up on the Prairies, as this native grass did. Perfect in the foreground of beds to hide the declining plants behind, or among boulders and on slopes for a modern, xeric look, you will love this grass for its ease of growth and the beauty it brings to your garden. Oh, did we forget that it’s hardy even in zone 5, unlike other red-flowering grasses of this type? Well it is.
Growing the Undaunted® Ruby Muhly Grass
Size and Appearance
The Undaunted® Ruby Muhly Grass is a perennial, long-lived warm season grass that grows into a mound of fine foliage that is between 18 and 24 inches tall and wide. The many narrow leaves rise from the base making a fountain-like mound like a cloud of soft green . Although the leaves are very thin, this grass doesn’t have a hard, spiky look. It forms a dense clump, without spreading and taking over your beds, and unlike many other clump-forming grasses it doesn’t die out in the middle. It is long-lived and once established it won’t disappear in a couple of years, as some other grasses can annoyingly do.
By late summer you will see the many tall flowering spikes rising above the leaves and approaching 3 feet tall. At first silvery-green, these soon turn a beautiful dusky dark reddish pink, and the color floats like a crimson cloud above your beds in a magical way, especially when the late fall sun shines through it.
Using the Undaunted® Ruby Muhly Grass in Your Garden
This beautiful grass is perfect for all those hot, dry spots in your garden, such as sunny slopes and among rocks. It’s essential when creating a water-wise, or xeric garden, but it also grows in regular beds, where it blends in with both shrubs and perennial flowers. Grow it with other native plants like asters, or with shrubs like hydrangeas. Use it to draw attention away from plants that bloomed early and are now looking past their best. As a single plant, or mass planted, it’s a unique addition you will love. For group plantings space each plant 12 to 18 inches from its neighbors. Of course, being a native plant, it’s an excellent choice for a natural garden, especially one in a hot, dry spot.
The Undaunted® Ruby Muhly Grass is much more cold-resistant than other grasses of this type, and more cold resistant than the wild species it came from. It is reliably hardy in zone 5 and all the way into the heat of zones 9 and 10.
Sun Exposure and Soil Conditions
Grow this grass in full sun. In shadier spots it will be floppy and bloom badly. It grows in any soil, but it must be well-drained, and sandy, drier soils are preferred. Avoid wet areas, especially through winter, as dormant plants are more sensitive to dampness. This grass is very tolerant of alkaline soil conditions. Established plants are extremely drought resistant.
Maintenance and Pruning
The Undaunted® Ruby Muhly Grass will take about 3 growing seasons to reach its potential, and during the first season some extra watering during dry periods is valuable. After that this truly is an easy grass, needing no attention even during the hottest and driest parts of the year, and living undisturbed for many years, keeping to a dense, non-invasive clump. Pests or diseases are rare, and it is entirely resistant to deer. The leaves are often perennial, and in time form a tangled mass. You can cut this plant back to the base in early spring, every year or two, to keep it neater, once it has been growing for a few years – leave young grasses untrimmed until they are well-established.
History and Origin of the Undaunted® Ruby Muhly Grass
Seep Muhly, Muhlenbergia reverchonii, is a perennial grass native to Oklahoma and Texas. It grows on rocky slopes and outcrops, and in seeps, which are areas where water periodically flows, with dry periods in between. In 2003 garden designers and plant experts Scott Ogden and Lauren Springer Ogden, were exploring in north-central Texas when they found a very sturdy population of this grass growing, which was about to be ploughed under for crops. Among the plants they found one that had striking red-pink flowers, instead of the usual brownish flower color. Colorado State University and Denver Botanic Gardens have a joint venture for new plants, called Plant Select®. The new grass was officially named ‘PUND01S’, and released with the registered trademark of Undaunted®, a mark registered to the University’s Department of Horticulture and Landscape Architecture.
