Triple Crown is a thornless, semi-erect blackberry valued for large fruit and excellent flavor. It is a summer-bearing cultivar that fruits on second-year canes (floricanes) and ripens later than most trailing blackberries. Plant form: One dormant bare-root plant Growth habit: Thornless, vigorous, semi-erect floricane bearer USDA zones: 5–9; protect overwintering canes at colder or exposed sites Chill requirement: Approximately 300–500 hours Pollination: Self-fruitful; flowers still depend on pollinator activity for good fruit development Sun: Full sun Spacing: About 5 feet between plants Harvest: Typically late summer into early fall in mild climates; timing varies by region Training and care Plant in fertile, well-drained soil and keep the root zone evenly moist. Use a sturdy trellis for the long, arching canes. Tip primocanes in summer to encourage lateral branches, shorten laterals during dormant pruning, and remove spent floricanes after harvest.
