Introduced in 1907 as an ornamental ground cover Native to east Asia including China Japan and Korea Mostly invasive in the southeastern states Still sold in nurseries due to its drought tolerance and rapid growth
An evergreen woody vine that grows as a climbing vine or vining shrub Spreads vegetativley by means of lateral roots Has thick waxy cuticle that makes it difficult to kill
Tolerates a variety of environmental conditions including poor soils, full to dense shade, and a wide pH range Grows in forests and forest gaps near urban areas Mainly occurs in the southeast but also found in New England and parts of the Midwest
Can reach 40 to 70 feet That impedes the growth of native species particularly spring ephemerals By depleting soil moisture and nutrients and blocking sunlight
Flower and fruit form only on plants that climb vertically Birds and other animals eat and disperse the seeds Seed also travel along Deer Creek
35 acres in Ladue 14 acres are woodlands and about 40% is covered with euonymus. Deer Creek runs through the property as well.
Use Accord or Rodeo because it does not contain a ionic surfactant that is detrimental to amphibians Rodeo does contain a surfactant that should not be used near water A study by John Solodar at Ruth Park sprayed four days in a row completely kills it Weed shipping or mowing vines to the ground and then spraying increases mortality rate Important to spray before dormancy period. Cuticle is beginning to break down
After a prescribed this past winter. The vines burned in the fire and we have been watching for resprouts
Since the plant is still sold in nurseries I thought I would give some alternative plants to replace euonymus fortunei in urban landscapes
