Crater Lake Blue Speedwell
Veronica austriaca 'Crater Lake Blue'
Plant Height: 10 inches
Flower Height: 15 inches
Spacing: 10 inches
Sunlight:
Hardiness Zone: 3b
Other Names: Austrian Speedwell, Hungarian Speedwell
Description:
Elegant and tiny saucer-shaped flowers of intense gentian blue cover this dense perennial; an excellent selection for a sunny front yard perennial or bedding plant border
Ornamental Features
Crater Lake Blue Speedwell has masses of beautiful spikes of royal blue flowers rising above the foliage from late spring to early summer, which are most effective when planted in groupings. Its serrated oval leaves remain dark green in color throughout the season.
Landscape Attributes
Crater Lake Blue Speedwell is a dense 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 should only be pruned after flowering to avoid removing any of the current season's flowers. 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.
Crater Lake Blue Speedwell is recommended for the following landscape applications;
- Mass Planting
- Rock/Alpine Gardens
- Border Edging
- General Garden Use
- Groundcover
- Container Planting
Planting & Growing
Crater Lake Blue Speedwell will grow to be about 10 inches tall at maturity extending to 15 inches tall with the flowers, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 10 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 8 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
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 not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. 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.
Crater Lake Blue Speedwell 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.
