Ornamental Features

Sentimental Blue Balloon Flower has masses of beautiful spikes of blue bell-shaped flowers rising above the foliage from early to late summer, which emerge from distinctive violet flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its narrow leaves remain dark green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Sentimental Blue Balloon Flower 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 has no significant negative characteristics.

Sentimental Blue Balloon Flower is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • Border Edging
  • General Garden Use
  • Container Planting

Planting & Growing

Sentimental Blue Balloon Flower will grow to be about 8 inches tall at maturity, with a spread of 8 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 6 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 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. This is a selected variety of a species not originally from North America.

Sentimental Blue Balloon Flower 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 larger 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. 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.
