    Jackmanii was the first of the modern hybrid large-flowered clematis to be grown in gardens and it continues to be very popular today. Many sources list it as hardy to zone 4, but in a more protected location it has been known to be hardy to zone 3. Since it gets so large, a sturdy support or trellis will be needed. It will tolerate being planted close to black walnut trees. Does not do well in heavy clay soils.
