Veronica subalpina, commonly known as Alpine Speedwell or Subalpine Veronica, is a perennial herb native to New Zealand. This plant is typically found at high elevations where it contributes to the diverse flora of the region’s grasslands and rocky habitats. It exhibits a moderate growth rate, reaching a height of 0.2-0.5 feet (0.06-0.2 meters) and spreading 0.5-1 feet (0.2-0.3 meters) wide. Alpine Speedwell forms a low-growing mat with lance-shaped leaves and bears clusters of bright blue, showy flowers during the summer months, adding a splash of color to the garden.

Alpine Speedwell is valued for its vibrant blue flowers and its ability to thrive in challenging mountainous conditions, making it a suitable choice for rock gardens, alpine collections, and as ground cover in well-drained areas. It is also utilized for border planting due to its compact size and attractive foliage. For optimal growth, it requires full sun to part shade and prefers medium to fast-draining loam or sandy soils. While it needs regular watering, it is important to avoid waterlogged conditions as this can lead to root rot. Alpine Speedwell is generally low maintenance but can be susceptible to powdery mildew and should be monitored for this disease.CC BY-SA 4.0
