Thinking about planting Japanese Knotweed, Giant Knotweed, or Silver Lace Vine in your garden? Please reconsider. Even "non-invasive" cultivars can contribute to the general problem of knotweed invasion, because hybridization can occur. Also, consider planting native species instead!
Photos of Japanese Knotweed
Below are links to photos of Japanese Knotweed in many stages of growth. This page documents the resprout of knotweed stems from an established rhizome, beginning in spring of 2002, and follows the plant through the summer, during flowering time. All photos were taken along the Monatiquot River in Braintree, Massachusetts.
