Prime-Ark 45 Primocane Blackberry Plant

Description

Description

Prime-Ark® 45 is an early, heavy-producing primocane blackberry that delivers one of the longest harvest seasons available — and fruit that stores exceptionally well long after picking. The erect canes make the firm, midnight-black berries easy to spot and harvest, and the dual-season production structure means you’re picking from June through frost. Disease resistant, cold hardy in Zones 5–8, and self-pollinating, it’s a reliable and rewarding blackberry for home growers who want consistent performance and a pantry-worthy harvest.

Two Harvests, One Long Season

Prime-Ark® 45’s primocane nature delivers a production structure that stretches from June all the way through the first frost. Second-year floricanes produce the heaviest crops in June, while first-year primocanes begin ripening in July and continue fruiting until frost. That extended window means fresh blackberries are available from early summer through fall — far longer than standard summer-bearing varieties.

Firm Fruit That Stores Well

What sets Prime-Ark® 45 apart from many other blackberry varieties is the storage quality of its fruit. The firm, medium-to-large berries hold up well after harvest — maintaining their texture and flavor for longer than softer varieties — making them practical for fresh eating over multiple days, canning, freezing, and any use where shelf life matters.

Erect Canes for Easy Management and Picking

The naturally erect cane habit keeps the planting organized and accessible without constant training or support. Combined with the firm, easy-to-spot midnight-black berries, harvesting is straightforward and efficient — an important practical consideration when the plants are producing abundantly over an extended season.
