Description

Panicum virgatum 'Shenandoah' is an ornamental grass with a compact, clumping habit. The key characteristics that differentiate it from the parent species, are its short stature, which at about 3' is likely the shortes and most compact P. virgatum cultivar. Also, and more notably its blue-green foliage develops fall colors of burgundy and purple as early as late June, which is much earlier than even other cultivars. It is thought that his color shift accounts for the plant's compact habit, because the lack of chlorophyll so early in the season likely stunts the plant's growth

Cultivation

As with the straight species, 'Shenandoah' is adaptable to a wide range of soil types, and moisture levels ranging from wet to dry. It is best grown under full some, but it will tolerate some shade.

Additional Notes

Many people involved in horticulture and garden design, believe that 'Shenandoah' will likely become the most popular of all Panicum virgatum cultivars. It was discovered by Hans Simon in Germany from a seedling of Panicum virgatum ‘Hänse Herms’, and assigned the variety name in 1990.

Would you like your plants shipped later? You may choose to do so in the shopping cart.

Note: Early spring shipments might include plants that have not yet broken dormancy, or have not been vernalized and will be frost-tender. Please use your best judgment when selecting your preferred ship week.

Did you know? When plants are available from multiple growers, we list growers closest to your location first.

Why choose plants from the nearest grower? Choosing a the grower closest to you makes it more likely the plants are consistent with your ecoregion and better adapted to your location. In addition, shipping plants shorter distances typically uses fewer resources, something we can all get behind!

32-Count Deep Plugs

32-count plug

Size
2 ¼” x 2 ¼” across by 4” deep. They are referred to as 32s, or LP32s®. They can also come as individual cells—sometimes called liners—in a holding tray.

Recommended Use
32s are landscape-ready plugs and can be planted as they are. Because they are slightly wider, but shallower than DP50s, some growers reserve this size for growing species with shallow and/or fibrous root systems. They can also be used as starter plants to be finished in gallon-size pots.

Pros
They hit the sweet spot by combining the benefits of young plants with deep root systems and the lower cost of 32 plugs per flat. The plants are still at a vigorous stage of growth and establish quickly in the landscape. Due to their large size, they require less TLC once planted than the smaller plug sizes. They are ideal for new installations as well as filling gaps in established plantings.

Cons
We haven’t really found any downsides to using DP50s. However, to install them we recommend purchasing a good soil knife, or a drill auger for large installations.

Shipping & Planting

SHIPPING INFO:

Shipping is free on all plants orders!

Your plants will ship using each grower’s preferred method: FedEx Ground, UPS Ground, or Spee-Dee Ground (in select midwestern states). Our growers ship orders Monday through Wednesday. The farther your plants need to travel, the earlier in the week they will ship. The goal is to have all plants delivered by the end of the week.

Shipping plugs:

Plugs are shipped in full flats, sometimes also referred to as trays. Multiple flats can be shipped in a single box. The flats are wrapped in netting or craft paper to secure the plants, and spacers are used between flats to keep the plants from being crushed.

When you unpack your plugs, the plants will have been somewhat flattened by the netting or craft paper. They will straighten out within a couple of days. You may also gently “fluff” them a bit to speed up the process. In some cases, your plants might have been cut back before packing, if the grower deemed them to have become too tall for safe packaging. Don’t worry, though, these guys know what they’re doing and would not compromise the health of the plants. They’ll fill back in in no time.

After receiving your plants’ journey in a dark box, it will be important to acclimate them to sunlight again. Over a couple of days, you should gradually move them into their preferred light exposure, and water them as per their requirement.

Although we always recommend putting your plants in the ground as soon as possible, they can stay healthy in the flats for a considerable amount of time. The key is to respect their growing requirements: if the species requires full sun, do not store them in the shade. If it is best adapted to dry soil, do not over-water.

PLANTING INFO:

Planting plugs:

We consider plugs ready to ship when the plants’ roots have filled the entire liner cell and the plants can easily be pulled out. In some cases you will have to go about it gently, wiggling the plant by the crown, and possibly squeezing the bottom of the liner to compress the growing medium and release the roots. Other times, the plants will appear to be root bound. They are not in the traditional sense. The plants are healthy but they have used up all the growing medium available to them. Plugs are at an aggressive stage of growth. As soon as planted the roots will immediately expand into your native soil. They establish faster than plants in larger containers, because they don’t have the luxury of a lot of growing media that can inhibit the roots from venturing outside of their comfort zone.

We are not going to address area preparation because the process can be complex and is always site-specific. However, as a rule, we recommend disturbing the soil as little as possible, and we do not recommend amending the soil. If you chose the right plant for the right conditions they will thrive. Any disturbance and amendments will only encourage weeds to emerge that never had a chance to do so before.

Installing plugs cannot be easier: dig a hole large enough for the roots to fit snugly inside, then water them in to eliminate air gaps. We recommend using a soil knife, sometimes referred to as hori hori, or a drill-adapted auger if it’s a large installation. If you use an auger, you will need a powerful drill. Depending on the size of the project and the type of soil, the process can be beyond what an average drill will bear. Mulching is recommended after installation to help keep weeds down while the plants establish. Be sure to keep it away from the crown of the plants. For large projects, you may want to mulch the area before planting, rather than tiptoeing through it after the fact. As a side note: if you are installing plugs in the fall, you might want to plant them so that the crown is about ¾” lower than the surrounding soil. The winter’s freeze/thaw cycles can push plugs out if the roots did not have enough time to establish and anchor them in.
