Ornamental Features

Sweet Kate Spiderwort has masses of beautiful clusters of royal blue flowers at the ends of the stems from early to late summer, which are most effective when planted in groupings. Its attractive grassy leaves emerge gold in spring, turning chartreuse in colour throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Sweet Kate Spiderwort is an herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting 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.

Sweet Kate Spiderwort is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Naturalizing And Woodland Gardens

Planting & Growing

Sweet Kate Spiderwort will grow to be about 18 inches tall at maturity, 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 fast rate, and under ideal conditions can be expected to live for approximately 10 years. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant does best in partial shade to shade. It requires an evenly moist well-drained soil for optimal growth. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
