In Illinois, Northern White Cedar was formerly listed as a state-threatened species, but delisted in 2004 (Mankowski 2012) and is localized to bluffs and cliffs of St. Peter sandstone and rocky outcroppings. Elsewhere, the species is abundant in sphagnum peat swamps, lake shorelines, and moist woods. This accession was collected on the southwest edge of the species native range and is one of the southern-most, known native localities in Illinois and thus may contain genetics for heat and drought tolerance. Genetics for this accessions were collected from two areas separated by approximately 6.50 miles. | 2120343 | WLP 2484 |

This southern form was originally discovered by Brand et al. 2022 (Ploidy, genetic diversity and speciation of the genus Aronia) and is known for having glabrous stems and leaves and a distinct phyllotaxy than other Aronia species. In addition, plants tend to bloom approximately two weeks later than all other Aronia taxonomic groups and the inflorescences/infructescences are more spreading and extended due to longer peduncles and pedicels within the cyme. Fruit maturity tends to occur 2 to 4 weeks later than tetraploid A. melanocarpa and 4 to 6 weeks later than diploid A. melanocarpa. Phenolic levels are much higher in comparison to other A. melanocarpa accessions (Brand et al., 2017 - Anthocyanins, total phenolics, ORAC and moisture content of wild and cultivated dark-fruited Aronia species.) | 1953928 | Ames 34014 |
