Landscape Attributes

Meadow Rue is an herbaceous perennial with an upright spreading habit of growth. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This is a relatively low maintenance plant, and should be cut back in late fall in preparation for winter. It is a good choice for attracting bees and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Meadow Rue is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use
  • Naturalizing And Woodland Gardens

Planting & Growing

Meadow Rue will grow to be about 18 inches tall at maturity extending to 32 inches tall with the flowers, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 14 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.
