Description:

Also marketed as V. teucrium or V. austriaca, this older variety is still outstanding with deep blue flowers contrasted exquisitely against delicate chartreuse-yellow foliage

Ornamental Features

Trehane Creeping Speedwell has masses of beautiful spikes of powder blue flowers rising above the foliage from late spring to early summer, which are most effective when planted in groupings. Its attractive crinkled oval leaves remain chartreuse in color throughout the season.

Landscape Attributes

Trehane Creeping Speedwell is a dense herbaceous perennial with a ground-hugging 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.

Trehane Creeping Speedwell is recommended for the following landscape applications;

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

Planting & Growing

Trehane Creeping Speedwell will grow to be only 4 inches tall at maturity extending to 8 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.
