Ornamental Features

Blue Midnight Beard Tongue has masses of beautiful spikes of navy blue tubular flowers with white throats and violet stripes rising above the foliage from early to late summer, which emerge from distinctive purple flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its narrow leaves remain green in colour throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Blue Midnight Beard Tongue 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 and hummingbirds to your yard. It has no significant negative characteristics.

Blue Midnight Beard Tongue is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Container Planting

Planting & Growing

Blue Midnight Beard Tongue will grow to be about 24 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. It grows at a fast 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 prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. 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. This particular variety is an interspecific hybrid. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Blue Midnight Beard Tongue is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our store for more information on how to protect it over the winter months.

At Shelmerdine, we treat this plant as a "HOBBY PLANT" meaning that it is not recognized as winter-hardy in our Zone 3 climate. However, there is a possibility that it could survive winter. Regardless of whether it survives a winter or not, this plant is only warrantied until Nov. 1 of its season of purchase.
