‘Twilight’ is a thornless, semi-erect, high-quality blackberry (Rubus subg. Rubus Watson) that has very firm, large, dark, and sweet fruit suited for the fresh market; it ripens in the early midseason for a semi-erect type of blackberry. ‘Twilight’ was released by the U.S. Department of Agriculture-Agricultural Research Service (USDA–ARS) breeding program in Corvallis, OR in cooperation with Oregon State University’s Agricultural Experiment Station. This cultivar is an offspring of blackberries similar in pedigree to Eclipse and Galaxy, that combine germplasm from the eastern and western North American blackberry germplasm pools (Finn et al., 2020a, 2020b). ‘Twilight’ produces good yields of very firm fruit with tough skin and an excellent, sweet flavor. ‘Twilight’ fruit should be well suited to fresh market production in the early-midseason because it was earlier than ‘Triple Crown’, had a similar appealing flavor as ‘Triple Crown’, but was much firmer and with a tougher skin. ‘Twilight’ is expected to be adapted to areas where other semi-erect blackberries (e.g., ‘Chester Thornless’, ‘Triple Crown’) can be grown successfully. A U.S. Plant Patent has been granted (USPP 30,879) (Finn, 2019).
