Eared coneflower

Rudbeckia auriculata

Also called Alabama Coneflower

A tall, long-lived perennial coneflower from acid bogs of the southeastern USA, reaching over 3 m, grown mainly in prairie restorations and botanic gardens. Its key to success is boggy, low-nutrient soil, since it struggles in ordinary garden borders and tends to lodge in rich soil.

Family
Asteraceae (Daisy family)
Light
Full sun, Part shade
Water
Keep the soil consistently moist to wet, as in a bog margin.
Soil
Acidic, low-nutrient peaty or boggy soil; avoid rich, fertile soil.
Temperature
Tolerates typical temperate hardiness of its native southeast US range; no specific limits recorded.
How easy
Hard
Native range
SE. U.S.A.

About

Rudbeckia auriculata (Perdue) Kral., commonly known as the eared coneflower, is a species of flowering plant in the Asteraceae Bercht. & J.Presl., native to acid bogs in the southeast United States.

How to grow it

This species is little known in cultivation as it is difficult to grow within a typical mixed or herbaceous border unless provided with boggy soil. R. auriculata is occasionally available from specialist nurseries but is typically only used in prairie restorations or within botanic gardens. One major drawback is R. auriculatas propensity to lodge, this is most severe when grown in rich soils that differ from the low nutrient peaty soils the species is adapted to

Where it grows

Rudbeckia auriculata is endemic to the USA especially the southeast. Most recorded populations occur in Alabama with one population in Georgia. Previously this species was found in Florida but this population is presumed extinct. The distribution and population of this species is reducing with the majority of sites producing fewer than 50 flowering stems annually. R. auriculata along with the closely related R. scabrifolia and R. morhii occupy habitats such as peat bogs and can be found in disturbed areas such as alongside roads and within grazed fields. Healthy beaver populations support R. auricuata by engineering rivers to slow waterflow and create bogs. R. auriuclata is found in similar habitats to R. scabrifolia and Sarracenia spp. Tourn. ex L.
