Razz (northern highbush): Zone 4-7 mid season 1.5 yo tissue cultured plant
RAZZ, tested as 11-104, is a sibling of the cultivars ‘Bluecrop’ and ‘Blueray’, and is a progeny of the cross GM-37 x CU-5 (two USDA selections from early in the history of the USDA blueberry breeding program). The cross was made by F.V. Coville (USDA) in 1934 and selected in 1941 (presumably) by G.M. Darrow (USDA) and J.H. Clark (NJAES). Its desirable characteristics are: reliable productivity, good yields (about 75% of ‘Bluecrop’), midseason ripening (slightly later than ‘Bluecrop’), medium to large fruit (similar to ‘Bluecrop’), medium to light blue fruit color, and excellent flavor with remarkable raspberry overtones. Its other characteristics are: acceptable scar and acceptable firmness (similar to ‘Blueray’; 120-129 g/mm deflection). Plants of RAZZ are vigorous and robust; they are upright and less willowy than ‘Bluecrop’. Its flowering time is similar to ‘Bluecrop’. RAZZ has flowers with a distinct creamy coloration and immature foliage with less anthocyanin coloration than its siblings ‘Bluecrop’ and ‘Blueray’. RAZZ is suitable for production in areas where highbush is typically grown. Zone 4 -7. 1.5 yo tissue cultured plant.

I'm intrigued by the idea of a blueberry that has some raspberry flavor overtones. It has Blue Crop as a parent, which is one of my favorite tasting blueberry., So I am looking forward to tasting the berries. It arrived well packaged and is extremely healthy. I have never seen any evidence of disease on the plants I receive from BU.
