Thornless Blackberry 'Columbia Star'

Thornless Blackberry ‘Columbia Star’ (Rubus fruticosus ‘Columbia Star’). Rubus fruticosus ‘Columbia Star’ is a thornless blackberry renowned for its delicate flavour and superior fruit quality. This bushy, trailing fruit shrub develops long, flexible stems ideal for trellis cultivation or structured fruit hedges. It produces large, shiny black, elongated, firm, juicy, and exceptionally sweet fruits, perfect for fresh consumption and artisanal processing. Its summer fruiting, on the previous year's canes, ensures an abundant mid-season harvest.

To plant 'Columbia Star' thornless blackberry, choose a suitable exposure: full sun. The recommended soil is: rich, well-drained, slightly acidic. Provide access to pick the fruit without breaking new canes. Pruning depends on the fruiting cycle: distinguish between canes that have produced shoots destined for the next harvest. Support can facilitate the maintenance of vigorous varieties. Water the root ball before planting and ensure water can drain after planting. During establishment, check the soil moisture by hand before watering again.
