Veronica decumbens, commonly known as trailing speedwell, is a perennial herb native to the South Island of New Zealand. It forms a low, spreading mat typically reaching 2-6 inches in height, with a width of 12-18 inches. The plant is characterized by its small, bright blue flowers that bloom profusely in spring and early summer, creating a striking display. The foliage is also attractive, with small, glossy, ovate leaves that remain lush throughout the growing season.

Trailing speedwell is valued for its ground-covering ability, low maintenance, and the vibrant color it adds to the landscape. It is often used in rock gardens, alpine gardens, borders, and as ground cover in sunny to partly shaded areas. In cultivation, it thrives in well-drained soils and requires moderate watering, particularly in dry conditions. While it prefers full sun to partial shade, it can tolerate a range of light conditions, making it versatile for various garden settings. It is not known for having significant disease or pest problems, but in wet or poorly drained soils, it may suffer from root rot.CC BY-SA 4.0
