Muhlenbergia reverchonii Undaunted®

Commonly called Ruby Muhly Grass, Muhlenbergia reverchonii Undaunted® is a low-maintenance Ornamental Grass that takes its name from a rugged disposition that’s unfazed by winter cold, summer heat, and drought. It forms a neat clump of light green foliage, and in late summer, mounts a display of airy, ruby-tinged flower spikes. Backlit by the afternoon sun, these blooms are breathtaking. This North American native perennial is a great choice for xeric or water-wise gardens, as well as dry borders where it mixes well with Blue Fescue, Yarrow, and Butterfly Weed. 'Pund01s'

Muhlenbergia, commonly called Muhly Grass, is a genus of about 150 species of mostly perennial Grasses growing in open, arid, and semi-arid areas of the Western Hemisphere, particularly in the xeric Southwest and dry prairie states. They are warm-season growers that form clumps of fine-textured basal foliage and inflorescences ranging from stiff, narrow spikes to clouds of airy pink or white. Native Muhlenbergia species and cultivars are tough and beautiful plants. They are extremely low-maintenance and drought-tolerant, useful in xeriscapes and water-conserving situations, and can take the heat. Well-draining soil is essential for winter survival. Here in Connecticut, we have taken advantage of extra-good drainage on a steep hillside site in full sun to grow Muhlenbergia reverchonii Undaunted® with great success. Plant in groups or drifts in full sun on rocky slopes, in sandy, unimproved soil, or as a single spectacular specimen skirted with other water-wise native plants, such as Solidago sphacelata ‘Golden Fleece’ or spring-blooming Phlox subulata.

We want our customers to receive strong, healthy plants that are ready to thrive in their gardens and homes. Here's what we'd like you to know about our shipping practices.

Delivery Timing

We aim to deliver your plants at as close to the proper time for planting in your area as possible. To do so, we consider the USDA Hardiness Zone to which we're shipping, current and forecasted weather at the destination and along the shipping route, and whether your plants are ready for transplant.

In spring, we ship first to the warmest regions and move north as planting conditions improve. For fall deliveries, we begin with the coolest regions and work south. We frequently adjust shipping schedules when extreme weather could put plants at risk while in transit or soon after arrival.

Because different plants reach readiness at different rates and are weather-sensitive in varying degree, a single order may be delivered via multiple shipments. Plants sold as part of a collection, or that are otherwise meant to arrive together, will be shipped together. Please contact our customer service team with two weeks' advance notice if you anticipate being away at the expected time of delivery. 

Tracking information for each package is delivered via email. 

Plant & Container Sizes

We deliver plants in various sizes and stages of growth, and the product detail pages of our website indicate the form and/or pot size in which the plant will be delivered. Pot sizes range from 1 pint to 1 gallon and larger. Many perennials, roses, shrubs and vines are delivered bareroot - that is, not in a container at all. Bulbs and tubers are generally delivered bareroot and fully dormant. We choose container sizes and delivery methods based on how each plant grows best, how we can minimize transplant shock, and how to minimize unnecessary bulk/weight in shipment. 

Caring for Your Plants Upon Arrival

It is important to acclimate greenhouse-grown plants to life outdoors. All plant shipments include simple instructions for handling your plants upon arrival. Further how-to information, including planting instructions, is available on each plant's product page.
