Boston Ivy Parthenocissus tricuspidata Plant Profile
When we moved from an old historic brick house in Annapolis to the brand new brick house in North Carolina we were not thrilled with the starkness of the look and missed the ivy covered wall to which we were accustomed. No, problem; the head gardener ordered Boston Ivy (not an really) and within one year our house looked as though it had been on its site for years. After another year we were also treated to the magnificent scarlet autumn foliage of this spectacular vine. And no, this vine does not hurt the mortar or brick house; it climbs by producing branched tendrils equipped with sticky disks that do not penetrate the surface. (It may, however, hurt painted surfaces.) This vine is deciduous (drops its leaves) and in the winter its woody leafless stems adorn our house with beautiful patterns. Note that the vine shades your house in summer reducing air conditioning costs, but lets the sun through in winter warming your house and decreasing heating costs.
