Columbia Star is a thornless trailing variety — needs a sturdy 5-6 ft trellis for the long canes. Bears on second-year (floricane) wood; first real crop 1-2 years after planting, ripening mid-July in Zone 7. After harvest, prune fruited canes to the ground and tie up the new primocanes for next year.

Two thornless trailing canes in Deck bed A, flanking a 2×2 garlic chives block. From One Green World; planted late May 2026.

Columbia Star is a thornless trailing variety — picks heavy mid-July in Zone 7 once established. Bears on second-year (floricane) wood, so a real first crop won’t show until 2027. For now I’m focused on training the long primocanes along the arch trellis above the bed.

    Both canes leafing out at the corners of the bed; garlic chives bulking up in the middle 2×2. The deck arch overhead will hold the canes as they extend.
