Solidago speciosa is indeed one of the showiest goldenrods. Its flowers are in a dense, upright panicle that is pyramidal in shape. The unbranched, rigid stems are reddish and up to 4' tall, with flowers clusters on the upper third. The inflorescences on showy goldenrod are erect, unlike the arching form typically associated with goldenrods. The leaves are alternate, lance-shaped, and up to 6" long at the base of the plant, decreasing in size as you move up the stem. Showy goldenrod is native to the Central and Eastern U.S., growing in open woods, fields, and roadsides. Expect a big display of bright yellow with a stand of this goldenrod!
Showy goldenrod is very easy to grow under typical garden conditions. It is tolerant of poor soil, and will thrive in slightly moist to slightly dry environments in full to part-sun. Overly moist, or fertile soil can lead to taller, weaker plants that will have a tendency to topple over without additional support. This species can provide intense color contrast in the late summer garden, or perennial border. It is also a favorite to naturalize wild gardens, prairies, and meadows. The blooming period lasts about a month, during late summer or early fall. Zones 3-8
Space plants 2'-3' on center.
The root system is fibrous and rhizomatous, and the species can spread vigorously in moist soils.
Solidago speciosa is an excellent late-season source of nectar and pollen for a variety of native bees and butterflies. Showy goldenrod has been used medicinally by indigenous communities for a wide range of applications—everything from easing childbirth, to treating burns, to managing lung conditions. Although often blamed for inflaming seasonal allergies, goldenrod pollen is spread via pollinators and is too large and sticky to be wind borne. The real culprits are lightweight pollen-bearers like ragweed, which rely on the wind to spread their pollen and bloom around the same time as goldenrod. People who are allergic to ragweed can be sensitive to goldenrod, but it would take direct contact with the plant to spark a reaction.

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 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.
