KTRS 550 Inside Out Show featured Plant Solidago Fireworks August 8 2009


Solidago ‘Fireworks’


Add Solidago ‘Fireworks’ (Goldenrod) to the Sun Rain Garden

Feature this upright goldenrod’s outstanding display of lacy bright yellow flowers in the late summer / fall landscape as a perfect solution for wet/dry spots!

Wrongly accused as instigator of hay fever, this innocent bystander is actually a great cut flower appreciated by homeowners “with water issues”. It is also great for attracting natural helpers to your garden, including butterflies!

Solidago rugosa ‘Fireworks’ is a landscape selection, chosen for its profuse flowers, study upright habit and doorstep gardening because of its non-aggressive good manners when used in cultivated spaces.
With a predictable steady growth rate, most specimens will reach 3-4’ tall and wide in 3 to 4 years if in average Missouri growing conditions.

Perfect for sunny rain gardens, this outstanding perennial can both be a design anchor as well as an erosion specialist regardless of fluctuating moisture levels throughout the season.

To keep a tidy landscape and extend the flower interest-go ahead and remove the finished flowers as they begin to fade. This will extend the bloom period, encourage more flowers to finish developing and stretch the color interest into the fall mum and aster season. .

For indoor use cut just as flowers open or till the fresh feeling of color just begins to slip. At that point, cut everything and use all you want as an indoor cut flower arrangement addition. Goldenrod can last for weeks in indoor flower arrangements.

If you are an primarily an “outsider”, and don’t bring flowers inside, enjoy them for as long as you like “ah natural” and just trim stems close to the base foliage near ground level before seed sets. Be aware that there needs to be some control in cultivated spaces if a managed look is desired! Restoration projects are cared for differently than cultivated green spaces!

Leaf rust is occasionally reported with the species but S.r. 'Fireworks' is said to be resistant to both rust and mildew. If it is affected, it is not likely to interfere with flowering or affect growth.

Care Factor Rating: 3 (It must be watered regularly till established but is very drought tolerant.) Plan to manage twice annually in late spring and as it completes it flower cycle. Divide or limit the area in use in the late spring once the primary plant reaches its desirable level by cutting around the base with a sharp shovel edge Remove excess material as needed. The slowly expanding clump grows 3-4 feet tall.
Many plants appear most balanced if the height and width are somewhat equal. When including this goldenrod in a design, consider leaving a 3’ minimum footprint. Plan to manage this plant twice annually.

'Fireworks' has proven it to be hardy to Missouri for several seasons and is on display in the perennial border at the Missouri Botanical Garden’s Kemper Center for Home Gardening. . It is not favored by deer. It was introduced in 1993 from the North Carolina Botanical Garden. Selected and named by Ken Moore of North Carolina Botanical Garden in 1970, it was introduced by Niche Gardens. It originated from a selected form of a coastal population of the species. It was also the top-rated cultivar in the 5-year goldenrod trials at the Chicago Botanic Garden (completed in 2001) that included 22 species and cultivars.

Because of its height, ‘Fireworks’ is often best placed at the back of the border. Plant with ironweed (Vernonia), Sedum 'Autumn Joy’, Asclepia incarnata and beauty berry (Callicarpa Americana)
