Danna produces fruit on primocanes and floricanes (everbearing blackberry), plants of this cultivar are vigorous and prolific, thornless. Primocanes and floricanes are erect in growth haЬit. The canes are best managed if trained to а hedgerow and а trellis with supporting wires used to prevent canes from falling over due to wind or heavy fruit loads. Leaves have yellow-green color.
Danna is early-ripening blackberry. The average floricane blооm peaks at the end of April, earlier than APF-45 and АРF-190T. The first harvest of floricane fruit begins in early June, compared to average first harvest on АРF-190T and APF-45. Primocane first ripe fruit date is second half of July on tipped primocanes. Fruit yields on floricanes average 3 kg per plant. Fruit yields on primocanes average 1 kg per plant. Primocane fruit harvest can Ье dependent on environmental conditions, most importantly temperatures being below 32 С to allow fruiting. Fruit size is medium, about 6 g per berry.
The fresh fruit rates good in flavor. The soluble solids concentration averages 11.7% on shiny blасk fruit harvested from floricanes and 11.9% from primocanes. Primocane fruit and flowers are bome on the cane terminus or on lateral branches if primocanes are tipped, and fruiting continues down the primocane during the season. Canes usually attain а length of approximately 1.8 m prior to the appearance of flower buds. The number of nodes down the cane that develop flowers is largely dependent on the length and conditions of the late summer to fall growing period.
Principal use - for home garden, lосаl fresh-market, or commercial shipping. Plants are hardy to minus 17 C.
Danna blackberry variety is moderately resistant to anthracnose, and have shown no evidence of susceptiЬility to orange rust.
