Strawberry Cultivars for Western Oregonand WashingtonE C 1618 R e vised Apr il 2014Chad E. Finn, Bernadine C. Strik, and Patrick P. Moore‘Totem’ (June-bearing)The cultivated strawberry (Fragaria ananassa), resulted from a cross between twowild strawberry species: Fragaria virginiana(meadow strawberry), which is native throughoutmuch of North America, and Fragaria chiloensis,which is native to the Pacific coast of North andSouth America. Colonists in eastern North Americasent the meadow strawberry, F. virginiana, back toEurope. A French spy, who was also a botanist, wasmonitoring the Spanish in Chile and brought plantsof F. chiloensis, which had been improved greatly bynative South Americans, back to Europe. By chanceor design, the two species crossed, and the offspringbecame the cultivated strawberry we know today.This publication briefly describes the main typesof cultivated strawberries. Tables 1–3 list cultivarswithin each type that are adapted to conditions westof the Cascades.June-Bearing StrawberriesThe primary type of strawberry is the June-bearingstrawberry. These cultivars are sometimes referred toas short-day strawberries because they initiate flowerbuds the previous summer/fall as the days becomeshorter. This type of strawberry is commonly grownin perennial matted rows, where runners are encouraged to root within the row each year to establishproductive crowns for the following year.Many California-developed June-bearing strawberry cultivars are available. However, many of thesecultivars, including ‘Camarosa’, ‘Chandler’, ‘CaminoReal’, ‘Gaviota’, ‘Lassen’, ‘Tioga’, ‘Torrey’, ‘Tufts’,and ‘Ventana’, are not good choices for the PacificNorthwest. The plants tend to be short lived, not veryproductive, and have poor fruit quality. June-bearingcultivars are listed in Table 1.Chad E. Finn, berry crops geneticist, USDA-ARS, Horticultural CropsResearch Unit, Corvallis, Oregon; Bernadine C. Strik, Extension berrycrops professor, Oregon State University; and Patrick P. Moore,scientist, Washington State University.

Everbearing StrawberriesAs people noticed that some types of strawberries bore small fall crops in addition to a springcrop, breeders and hobbyists began selecting forthis trait. The result was everbearing strawberries,such as ‘Ft. Laramie’, ‘Gem’, ‘Ogallala’, ‘Ozark Beauty’,‘Quinault’, and ‘Rockhill’. Everbearing strawberriestend to have large spring and fall crops, with littlefruit in between. An everbearing cultivar is listed inTable 2.Day-Neutral StrawberriesIn the 1970s, day-neutral (remontant) strawberries were developed at the University of California.Day-neutral strawberries flower throughout thegrowing season as long as temperatures are below90 F. Periods of hot weather will cause a temporarygap in fruit production. Day-neutral strawberriesdo not produce as many runners as the other types,so they are usually grown commercially with plasticmulch in a hill system, where runners are removed tomaintain individual plants. This type of strawberrycan be grown in annual or perennial production systems. Cultivars are listed in Table 3.‘Puget Crimson’ (top) and ‘Puget Reliance’(bottom), both June-bearingDistinguishing between everbearing andday-neutral cultivars can be confusing for the homegardener. Day-neutral cultivars are “everbearing,”whereas the old everbearing cultivars produce twodistinct crops—one in the spring and one in thefall. Furthermore, both day-neutral and everbearing cultivars are usually sold as “everbearing” inretail nurseries.Fragaria vesca (Alpine)StrawberriesFragaria vesca (fraises des bois or woods strawberry) is also commonly found throughout thenorthern hemisphere. Many “alpine strawberries”have been developed from this species. Cultivarsinclude ‘Alpine’, ‘Baron Solemacher’, and ‘Ruegen’.Plants are moderately vigorous but have poor durability because they are highly susceptible to viruses(these cultivars often are used as virus indicators).Berries are small, with a bright red external color andpale internal color. They are soft, very aromatic, andhave a mild flavor. Berries are suitable only for freshuse. Yields are low, and commercial value is limited.2‘Seascape’ (top) and ‘Albion’ (bottom),both day-neutral

Cultivar Table NotesTables 1–3 list June-bearing, everbearing, andday-neutral strawberry cultivars that are adaptedto conditions west of the Cascades. Most of thesecultivars are not adapted to colder regions in thePacific Northwest. In colder regions, choose cultivars that grow well in the Midwest or easternUnited States, including ‘Allstar’, ‘Jewel’, ‘Honeoye’,‘Earliglow’, ‘Clancy’, ‘Lateglow’, ‘Annapolis’, and‘Cavendish’ (June-bearing) or ‘Monterey’, ‘SanAndreas’, ‘Tristar’, and ‘Tribute’ (day-neutral).Not all of the listed cultivars are available innurseries.DurabilityDurability refers to how long lived a cultivarmight be in the field. Plant viruses and otherdiseases, particularly root rot, can shorten theproductive life of a planting. Some cultivars, suchas ‘Hood’, often bear for only 1 or 2 years, whereasothers, such as ‘Tillamook’, often produce for several years.Fruit Descriptions and YieldDescriptions of yield, flavor, and berry size areprimarily based on results of trials by the USDAARS/OSU cooperative breeding program at theOSU North Willamette Research and ExtensionCenter in Aurora, Oregon, and the WashingtonState University breeding program in Puyallup,Washington. If a cultivar has not been tested atthese sites, yield and berry descriptions are basedon grower experience. Yield ratings are based oncomparison to other cultivars of the same type.Fruit traits, particularly flavor, can vary tremendously based on location (because of differences intemperature and rainfall), cultural practice, and, ofcourse, personal preference.Commercial ProductionA commercial value score is provided to helpcommercial growers select appropriate cultivars forfresh and processed markets:1 Appropriate for most commercial operations2 May have commercial value but:(a) not enough is known about its performanceor(b) may meet a specific requirement(e.g., unique color or very early harvest) buthas a negative trait (e.g., low yield or poorshipping quality)3 Unlikely to have good commercial valueSmall Farm, U-Pick, and HomeGardensCultivars that are well suited to small farms,local sales, U-pick farms, and home gardens arenoted as such.What if you find a cultivar that’s noton these lists?Find out as much about it as you can: Is it June-bearing, everbearing, orday-neutral? Does the nursery’s description indicate thatit’s susceptible to any diseases, such as rootrot or viruses? What’s the fruit like?Remember: If you purchase a cultivar that is noton these lists, it probably hasn’t been extensivelytested in this region. It’s best to try a few plantsfirst and see how well they grow and how you likethe fruit.“Ease of capping” refers to how easily the fruitpick without the cap or calyx—an important traitfor processing.3
