Can boston ivy be planted now (mid november) in Zone 5 or is spring best?
Boston Ivy, Parthenocissus tricuspidata ‘Veitchii’ is a vigorous climbing vine with glossy, bright green foliage. It is considered an invasive plant in some US states. As a result be careful not to plant it near natural areas; it may escape it’s boundaries and threaten native plants. Prune the vine once a year to keep it in check.
The foliage can vary in shape between deeply toothed, three-lobed leaves, to three seperate leaflets, but it all turns spectacular shades of red-purple in autumn if planted in a partially shaded spot. Mature specimens also provide an important habitat for insects and small birds.
If you wish to have your Boston ivy scale the walls of a building, make sure that you want it as a permanent fixture. Once Boston Ivy gets a hold, removing it may cause damage to the wall. It is better to train this vine to grow on trellises.
It is best to plant Boston Ivy in late spring and early summer, after the last frost date when the soil is warm and the ground is moist. You don’t want the roots to dry out, so the ideal time is when the sky is overcast. If it’s a very sunny day, plant in early morning or evening.
