Aubert's knotweed (Polygonum aubertii)

Silver Lace Vine (Polygonum aubertii). Polygonum aubertii, known as silver lace vine, is a vigorous climbing plant recognized for its rapid growth and abundant flowering. This deciduous liana quickly forms a dense screen, ideal for covering pergolas, fences, trellises, or walls in a short amount of time. Its long, flexible stems bear heart-shaped, light green foliage that creates a light and elegant mass of vegetation. In late summer and early autumn, the plant is covered with a multitude of small, creamy-white flowers gathered in long, airy panicles that create a very decorative cloud of blooms.

To plant silver lace vine, choose an appropriate exposure: sun to partial shade. The recommended soil is ordinary to poor, well-drained soil. Water the root ball before planting and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again. Spread mulch around the base, leaving the crown clear. Avoid systematic fertilizer applications without considering the soil's richness. In Quebec, choose a period when the ground is thawed and easy to work.

Allow for a width of 5 m (16 ft) to plan the placement of this plant in the garden. The indicated height of 10 m (33 ft) helps in choosing its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Pair this variety with plants that have compatible light and water requirements. If you are considering a container, first check that its volume and drainage are suitable for root development. Potted roots are more exposed to cold than those planted in the ground.
