The Q&A Archives: Hibernia Lilac

Question: I bought this lilac vine some 6 years ago. I planted it and put up a trellis for it to grow on. My neighbor put a trellis up on her side . The vine became massive and very woody. It broke the trellis and fell over. I cut it all down, it is a growing fast and is the size of a small shrub. My question is, if I don't use a trellis will the vine grow upright like a bush and not become so woody? How do I keep it leafy and not woody, full of dead brush and twigs ?


Answer: Hardenbergia violaceae is the Australian Lilac Vine. This twining evergreen vine produces large, cascading sprays of white, purple and pink flowers from late winter into early spring. This beautiful triad of color creates a fabulous look for walls, fences, arbors or as a trailing groundcover. It will reach more than eight feet in length. The lustrous green foliage has large leaves, two to four inches long. It prefers full sun to part shade and well-drained, light soil that is kept evenly moist. It is a trailing plant by nature and will not grow into a shrub form but you can keep it under control with judicious pruning throughout the spring and summer months. Periodic pruning will encourage more leafy growth and remove the bare wood from the previous season. Enjoy!
