Description
Clematis viorna is a low-growing, deciduous, non-woody perennial vine. It has a creeping habit and will also climb up structures, natural or man-made, to a height of 10' by means of tendrils. The flowers are thick and leathery, resemble bells or upturned vases, and vary in color from pink or purple to red. These give way to very attractive, spidery seed heads that persist on the vine well into fall.
Cultivation
Vasevine is easy to grow, adaptable, and non-invasive. It is best grown in part-sun, in rich, moist well-drained soil. It will also tolerate full sun in a wetter location, or part-shade in a dryer one. It can be left to ramble and form a loose low-growing thicket, or trained up a fence or trellis. Flowering can extend for a couple of months, between between May and August. Zones 5-8
Additional Notes
Clematis viorna is commonly found on east facing slopes of the lower Appalachians, an area with the richest variety of native Clematis.

SHIPPING INFO:

Shipping is free on all 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 you 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, aan 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.
