BLACKBERRY THORNFREE - Perron
Perron blackberry was developed in Canada and is a vigorous thornfree variety with canes that grow up to 3.5 meters (12 feet) long. Large delicious berries ripen over several weeks in late summer and are very easy and "painfree" to pick. Perron's self-fertile blackberry canes like to be planted in warm sunny location moderated from bitter cold winter winds...maybe south side of a building or other windbreak. Good hardiness( zone 4-5) for any Canadian city or farm with windbreaks or snow cover to help protect canes in winter.
