Spiked Speedwell: A European Perennial for North American Gardens
Meet spiked speedwell (Veronica spicata incana), a charming European perennial that has found its way into North American gardens. This silvery-leaved beauty brings a touch of old-world elegance to modern landscapes, though it’s worth understanding both its benefits and considerations before adding it to your garden.
What Is Spiked Speedwell?
Spiked speedwell is a non-native perennial forb that has established itself in parts of Canada, particularly Ontario. Also known by its synonym Veronica incana, this plant belongs to the speedwell family and shares characteristics with other Veronica species. As a forb, it’s a non-woody vascular plant that dies back to the ground each winter and returns from its roots in spring.
Geographic Distribution and Native Status
Originally from Europe and Asia, spiked speedwell has naturalized in Ontario, where it reproduces on its own without human intervention. While it’s not considered invasive or noxious, it’s important to remember that this is an introduced species rather than a native North American plant.
Garden Appeal and Characteristics
What makes spiked speedwell attractive to gardeners? Here are its standout features:
- Distinctive silvery-gray foliage that provides excellent contrast in the garden
- Spikes of small blue to purple flowers that bloom in summer
- Compact, mounding growth habit perfect for borders and rock gardens
- Drought tolerance once established
- Low maintenance requirements
Where to Use Spiked Speedwell
This versatile perennial works well in several garden settings:
- Rock gardens where its silver foliage creates striking contrasts
- Perennial borders as a front-of-border plant
- Cottage-style gardens for a naturalized look
- Dry gardens where its drought tolerance shines
- Ground cover in sunny areas with well-draining soil
Growing Conditions and Care
Spiked speedwell is refreshingly easy to grow when given the right conditions:
- Sunlight: Full sun for best flowering and foliage color
- Soil: Well-draining soil is essential; avoid wet, heavy clay
- Water: Drought tolerant once established, but appreciates occasional deep watering
- Hardiness: Suitable for USDA zones 3-8
- Maintenance: Minimal care required; deadhead for extended blooming
Planting and Care Tips
Getting the most from your spiked speedwell is straightforward:
- Plant in spring or early fall when temperatures are moderate
- Space plants according to their mature size to ensure good air circulation
- Avoid overwatering, especially in heavy soils
- Deadhead spent flowers to encourage more blooms
- Divide clumps every 3-4 years to maintain vigor
- Be aware that it may self-seed in favorable conditions
Wildlife and Pollinator Benefits
The flower spikes of spiked speedwell do provide some benefit to pollinators, attracting bees and butterflies during its blooming period. However, as a non-native species, it doesn’t support native wildlife as effectively as indigenous plants would.
Should You Plant Spiked Speedwell?
The decision to grow spiked speedwell depends on your gardening goals. While it’s an attractive, low-maintenance perennial that’s not considered problematic, gardeners interested in supporting native ecosystems might consider native alternatives instead.
If you’re drawn to the silvery foliage and blue flowers, consider these native alternatives that provide similar aesthetic appeal while supporting local wildlife:
- Native asters for late-season blue flowers
- Wild bergamot for aromatic silver-green foliage
- Native salvias for drought tolerance and pollinator appeal
The Bottom Line
Spiked speedwell can be a lovely addition to the right garden, especially for those seeking low-maintenance perennials for dry, sunny spots. Just remember that every plant choice is an opportunity to support native ecosystems, so consider whether this European beauty aligns with your gardening values and local growing conditions.
