plant sale text: Excellent delicate vine for the garden, use this plant as a climbing accent in shrubs or small trees. The thin twines will not harm your woody plants and the pink to lavender urn-shaped flowers will provide interest. Of course a fence post or trellis will work just as nicely. Anywhere you will be able to enjoy the show. The seed heads are reminiscent of little Truffula tree tufts (remember The Lorax?) and are seen into autumn. An easy vine to grow and tolerant of soil type in a filtered shade location.
