  • Care
    Care Information
    Provide rich, acidic, well-drained soil. Shelter from harsh afternoon sun in very hot, arid climates. Water deeply and regularly. Before new growth begins in early spring feed with an acidic fertilizer, and prune away dead or non-fruiting wood to promote growth and berry production. Recommended winter chill: 1,000 hours.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    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.
