- History & LoreHistory:Perpetua was developed by Chad Finn at the USDA-ARS in collaboration with Oregon State University. Discovered in Corvallis, Oregon, originating from open pollinated seed of CVAC 45 (PI 296412) in the USDA-ARS National Clonal Germplasm Repository. CVAC 45 was collected from the wild in 1963 in Monmouth, Me., listed as Vaccinium corymbosum L. (highbush blueberry) by the USDA-ARS GRIN database. Because this parent plant's characteristics are intermediate to those of V. corymbosum and V. angustifolium Aiton (lowbush blueberry, and both species are found in the region where the accession was collected, CVAC 45 is presumed to be a hybrid between the two species. Perpetua is unique in that it produces flower buds that break without winter dormancy, then flowers again to produce a a late-season crop. While many blueberries will produce a few fruit in the fall at the tips of new growth, 'Perpetua' will produce on 12-16 nodes of new growth.
