  1. The Multiflora Rose Project by: David Kauffman

  2. About the Multiflora Rose • Scientific name: Rosa multiflora Thunb. • Common names: Multiflora rose, baby rose, Japanese rose • Native to Japan, Korea, Eastern China • Description: thorny, perennial shrub, flowers in May with white and yellow flowers

  3. Life Cycle • Beginning in May or June- clusters of white and pink flowers appear on plant • During the Summer- small red fruits develop and stay until winter • Seed germination assisted by birds • Reproduces sexually and asexually

  4. Problematic? Multiflora Rose is very prolific and can grow very dense- crowds out native species Causes death of native species Distribution occurs throughout US except for the central areas This rose has a high tolerance to different soil conditions, therefore can grow almost anywhere

  5. How did it come here? • Originally from Japan • Planting in the US was encouraged by U.S Soil Conservation Service to help soil erosion • Promoted by wildlife managers as a source of food and cover to animals • Since the 1960s it was been a serious problem due to its dense growing habits

  6. How to deal with it • Chemical Control- application of herbicides has proven effective to destroy root system and prevent re-sprouting • Biological Control- 2 insects feed on rose- the rose seed chalid wasp, and the larva of the rose stem girdler beetle • Mechanical Control- cutting or mowing at a rate of 3-6 times per growing season- proven effective in achieving high mortality

  7. Spread • The Multiflora rose reproduces by seed and by forming new plants from the tips of arching canes that contact the ground • Each plant may produce a million seeds per year which can stay viable in soil for 20 years • Important to control the spread of this rose to enable a large biodiversity of plants • People should care and take steps to stop its spread. If it is not stopped, our environment will be a giant field full of thick weeds
