Best grown in well-drained sandy loams with regular moisture in full sun to part shade. Tolerates some drought. Tolerant of a wide range of soil conditions. Plants are less apt to spread invasively in poor, lean soils. Vines need a support structure upon which to grow unless grown as a sprawling ground cover. This is a somewhat weedy vine that spreads quickly by rhizomes. May be pruned back each year in late winter to early spring. To renovate, prune back in late winter to 1-3’ from the ground. To keep within bounds, trim off excess growth as needed throughout the year.
Silver lace vine is a vigorous, adaptable, fast-growing, deciduous, twining vine that typically grows 25-35’ (12-15’ in one year). Ovate leaves (to 3.5” long) emerge tinged with red, but mature to a bright green. Masses of small, fragrant, creamy white flowers in profuse, narrow panicles cover the vine over a long bloom period of mid-summer to fall. From a distance, this vine is similar in appearance to autumn sweet clematis (C. paniculata). Synonymous with Polygonum aubertii and Polygonum baldschuanicum.
No serious insect or disease problems. Watch for Japanese beetle.
Provides quick cover in sun or shade for trellises, fences, arbors, pergolas and walls. May also be sprawled over the ground as a ground cover to camouflage rock piles or old tree stumps or to provide soil stabilization for banks. Best to grow on structures or grounds that are not adjacent to areas where the invasive tendencies of this vine could become a problem.
