2022 Perennial Plant Of The Year - Little Bluestem

The Perennial Plant Association is pleased to promote Little Bluestem (Schizachyrium scoparium and cultivars) as the 2022 Perennial Plant of the Year®. The wider selection of Schizachyrium scoparium and cultivars allows the perennial expert in any region to select and promote the cultivars that do best in his or her location!

PPA Board members selected top performers in their regions and shared appealing details about each one. Highlights of each selection are below:

Central region - Richard Hawke of the Chicago Botanic Garden selects Schizachyrium scoparium 'Jazz' for the Central region. Richard notes, "The striking silvery blue leaves of 'Jazz' are most comparable to 'The Blues’, but at 36 inches tall and 30 inches wide, 'Jazz' is a foot shorter than 'The Blues' and has sturdier stems.

Southern region - Shannon Currey of Hoffman Nursery selects Schizachyrium scoparium 'The Blues' for the Southern region. Shannon comments, "In the South, our humidity, high nighttime temps, and wet springs can slow down some Little Bluestem. ‘The Blues’ is a strong, vigorous grower and has fantastic color. Blues, pinks, purples in the summer followed by reds and oranges in the fall. In the right conditions, it stands out for us."

Canadian region - Tony Post of Brookdale Treeland Nurseries - Valleybrook Farm, choses Schizachyrium scoparium 'Standing Ovation' for the Canadian region. Tony says, “This selection adds excellent texture to the summer garden. Burgundy highlights add late season interest. Seed heads are attractive, particularly when backlit."

Western region - For the Western region, Nanci Hollerith Allen of MarkWatch Plants notes that Schizachyrium scoparium can be a tricky plant unless you have reasonably dry, well-drained soil. She shares two recommended cultivars for the Pacific Northwest and the Rocky Mountain region: 'The Blues' and 'Standing Ovation'.

Great Lakes region - Patty Steinhauser of Stonehouse Nursery chooses Schizachyrium scoparium 'Carousel' for the Great Lakes region. Patty says, "This uniquely mounded selection forms a wide clump of blue-green foliage that emerges nearly horizontal and matures into strong, upright stems that remain standing through inclement weather and winter. It takes on pink, copper and orange-red tones in fall topped with tiny seed tufts."

Mid-Atlantic region - Taylor Pilker of Cavano’s Perennials suggests 'The Blues', 'Standing Ovation', and 'Jazz'. Taylor likes ‘Blue Heaven’ because “it is taller and has good autumn color with a wide range of shades of burgundy and pink."

Best And Most Reliable Coneflowers

Echinacea 'Artisan Soft Orange'

In 2020 MT Cuba Center in Greenville, DE released their most up to date ratings. This represents an updated test summary from their previous 3-year Echinacea (coneflower) variety trial in 2007-2009. The new report lists many more coneflower introductions and compares some newer cultivars against some of the tried-and-true top performers from the 2007-2009 trial.

In addition, MT Cuba conducted a pollinator survey to determine the cultivars that were most attractive to pollinating insects. This data was collected by their Pollinator Observation group. They tallied insect visitation to help determine ecological value of plants in our trials. For Echinacea, special attention was paid to the difference between single and double flowers in their ability to attract pollinators.

The best performing coneflowers in the trial are E. purpurea ‘Pica Bella’, E. ‘Sensation Pink’, E. ‘Santa Fe’, E. ‘TNECHKR’ (KISMET® Raspberry), E. ‘Snow Cone’, E. ‘POST301’ (Postman), E. ‘Glowing Dream’, E. ‘Purple Emperor’, E. purpurea ‘Fragrant Angel’, E. ‘TNECHKIO’ (KISMET® Intense Orange), E. ‘Balsomcor’ (SOMBRERO® Hot Coral), and E. ‘Julia’.

Important to gardeners: if you live in the mid-Atlantic States, results from the MT Cuba trial should be most useful and are posted online on the MT Cuba website. Midwest gardeners should look to recent Echinacea evaluations at the Chicago Botanical Gardens.
