Perpetua® is a true double-cropping blueberry that sets one crop of fruit in mid-summer, and then flowers and fruits a second time to provide ripe fruit in the fall. The leaves are dark green, somewhat shiny, and curly or twisted in the spring and summer, turning to deep reds and greens in the winter. The new canes are bright yellow and red in winter. Perpetua® has smallish berries that are mild and sweet.
