Ornamental Features

Siberian Bugloss features airy cymes of sky blue flowers at the ends of the stems from early to late spring. The flowers are excellent for cutting. Its heart-shaped leaves remain emerald green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Siberian Bugloss is an herbaceous perennial with a mounded form. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This is a relatively low maintenance plant, and should be cut back in late fall in preparation for winter. It has no significant negative characteristics.

Siberian Bugloss is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Groundcover
  • Container Planting

Planting & Growing

Siberian Bugloss will grow to be about 12 inches tall at maturity extending to 16 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 15 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 partial shade to shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. This species is not originally from North America. It can be propagated by division.

Siberian Bugloss is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
