Kolomikta Kiwis (Actinidia kolomikta) The kolomikta kiwi varieties are known to be hardy to -40C. Their highly decorative vines are more shade-loving and require less pruning since they are not as fast growing. They do start to bear earlier, sometimes in the second year. The fruit is smaller but starts to ripen earlier in the season and can be harvested continually over a longer time period. Bareroot plants
