Meet Speedwell
A reliable perennial with slender spikes of blue, pink, or white flowers that add vertical accent to borders and rock gardens. Speedwell is easy to grow in average, well-drained soil and blooms for several weeks in early to midsummer. Deadhead spent spikes to encourage reblooming and divide clumps every few years.
When to plant Speedwell
Speedwell can be grown from seed sown indoors 8-10 weeks before the last frost. Surface-sow on moist compost, as seeds need light. Germination takes 14-21 days at 18-20°C. Seed-grown plants usually flower in the second year. Named cultivars must be propagated by division in spring or by basal cuttings in late spring for identical plants. Division is straightforward—lift clumps, separate into sections with roots, and replant.

How to grow Speedwell
Speedwell is a dependable, easy-going perennial that produces slender tapering spikes of small flowers in shades of blue, violet, pink, and white. The spikes add valuable vertical accent to border plantings, rising 30-60cm above neat mounds of dark green foliage. Speedwell blooms from early to midsummer and, with diligent deadheading, often produces secondary flushes into early autumn.
Plant in full sun to partial shade in average, well-drained soil. Speedwell is adaptable and undemanding, tolerating a range of soil types from sandy to clay as long as drainage is reasonable. Space 35cm apart and water to establish. Once settled, speedwell is moderately drought-tolerant though it flowers best with regular moisture.
Deadhead individual spent spikes by cutting back to the nearest side shoot or set of leaves. This encourages secondary flower spikes and keeps the plant looking tidy. In autumn, cut all growth to ground level. Divide clumps every 3-4 years in spring to maintain vigor and prevent the center from dying out.

Speedwell's best neighbours
Speedwell's slender spikes provide excellent vertical contrast to rounded flowers like daisies, coneflowers, and geraniums. Plant alongside Shasta daisies, coreopsis, and daylilies for a classic cottage garden combination. Blue speedwell paired with yellow achillea and white Shasta daisies creates a fresh, cheerful color scheme. The compact mounding habit makes speedwell an excellent front-of-border plant.

Feed it well
Speedwell grows in average, well-drained soil with a pH of 6.0-7.5. It is adaptable to sandy, loamy, or clay soils provided drainage is adequate. Incorporate a light amount of compost before planting. Feed in spring with a balanced slow-release fertilizer. Avoid rich, heavy feeding that can produce lax growth. Mulch lightly to conserve moisture and suppress weeds.

Hardiness Zone Compatibility
From seed to harvest, stage by stage
Seed Germination
Veronica seeds are tiny and require light to germinate. Surface-sow on moist, well-draining seed-starting mix and keep at 18-21°C. Germination is often irregular, taking 14 to 21 days. Do not cover seeds with soil as they need light exposure to trigger sprouting.
Seedling Development
Seedlings develop their first true leaves and begin forming a small rosette. Growth is slow at this stage and plants are delicate. Thin seedlings to about 5 cm apart if sown directly, or transplant into individual pots once they have two sets of true leaves.
Vegetative Growth
Plants establish a dense basal mat of lance-shaped foliage. The root system expands and the plant begins to spread through short rhizomes. Leaves are opposite, finely toothed, and typically 5 to 8 cm long. By the end of this stage the plant forms a compact mound roughly 30 cm across.
Budding and Flowering
Upright flower spikes emerge from the center of the foliage mound, reaching 30 to 60 cm tall depending on the cultivar. Each spike is densely packed with small tubular flowers that open from the bottom upward. Bloom colors range from violet-blue and deep purple to pink and white. Peak flowering occurs from June through August in most temperate climates.
Seed Set and Late Season
After flowering, small capsules form along the spent spikes containing numerous tiny seeds. The foliage begins to yellow and die back as temperatures drop in autumn. In milder climates, some basal foliage may remain semi-evergreen through winter.
Winter Dormancy
Veronica spicata enters dormancy as winter sets in. The above-ground growth dies back to a low crown at soil level. The plant is hardy to USDA zones 3 through 8 and typically survives winter without protection in those regions. Root systems remain alive underground, storing energy for the following spring.
Spring Regrowth
As soil temperatures rise above 7°C in spring, fresh green shoots emerge from the dormant crown. Established plants grow vigorously and quickly reform their basal foliage mound. This is the ideal time to divide overcrowded clumps every three to four years to maintain plant vigor and improve airflow.
Mist the surface gently to maintain consistent moisture without disturbing the fine seeds. A humidity dome helps retain moisture during this stage.

Harvesting Speedwell
Speedwell spikes make attractive additions to mixed bouquets, adding a vertical element that complements round-faced flowers like daisies and roses. Cut when the lower half of the spike is in bloom. Stems last 5-7 days in fresh water. Deadheading spent spikes in the garden promotes additional flowering flushes.

Storage & Preservation
Speedwell flowers can be pressed for botanical crafts, though the small flowers are delicate to work with. The spikes dry reasonably well if cut at peak bloom and hung upside down for 2 weeks. For garden propagation, divide established clumps in spring or take softwood cuttings from basal growth in late spring.
What goes wrong — and the fix
Downy Mildew
DiseaseYellow patches on upper leaf surfaces with corresponding grey-purple fuzz on undersides. Can cause significant defoliation.
Leaf Spot
DiseaseBrown or black spots on leaves, sometimes with yellow halos. More common in wet seasons.
Aphids
PestSmall green insects clustering on flower buds and new growth in spring. Distorted flower spikes.
Troubleshooting Common Problems
The most common issue is flopping in too much shade or overly rich soil—full sun and lean conditions produce the sturdiest plants. Center dieback in old clumps is normal; divide every 3-4 years to rejuvenate. Some varieties are more prone to downy mildew than others; choose resistant cultivars in humid climates. Speedwell is otherwise a remarkably trouble-free, reliable garden perennial.
Growing Tips
- Plant in full sun for the best flowering performance. Veronica tolerates light shade but produces significantly fewer flower spikes and may develop leggy, floppy growth in less than six hours of direct sunlight.
- Ensure excellent soil drainage as veronica is far more likely to die from wet winter roots than from cold temperatures. Amend heavy clay soils with coarse sand, perlite, or fine gravel before planting.
- Space plants 30 to 45 cm apart to allow adequate air circulation, which helps prevent powdery mildew and other fungal issues during humid summer weather.
- Water deeply but infrequently once plants are established, allowing the top few centimeters of soil to dry between waterings. Overwatering promotes root rot and weakens the plant.
- Deadhead spent flower spikes by cutting them back to the nearest set of leaves rather than just removing the tip. This promotes bushier regrowth and a stronger second bloom.
- Divide clumps every three to four years in early spring just as new growth emerges. This prevents the center of the clump from dying out and rejuvenates flowering vigor.
- Apply a 5 cm layer of organic mulch such as shredded bark around plants to conserve moisture and suppress weeds, but keep mulch a few centimeters away from the crown to prevent rot.
- Avoid high-nitrogen fertilizers which encourage leafy growth at the expense of flowers. A single spring application of a balanced or phosphorus-rich slow-release fertilizer is sufficient for the entire season.
- Combine veronica with companion plants like Echinacea, Salvia, ornamental grasses, and Nepeta for a naturalistic planting scheme that provides continuous color and diverse pollinator resources from late spring through autumn.
- In regions with heavy winter snow, resist the urge to cut back foliage in late autumn. The dried stems help trap insulating snow around the crown and protect the roots from extreme cold.

Where Speedwell comes from
Veronica spicata, commonly known as spike speedwell, is a herbaceous perennial native to the grasslands, rocky meadows, and open woodlands of Europe and northern Asia. Its natural range extends from the British Isles and Scandinavia through central Europe, the Balkans, and across the vast steppes of Russia into Siberia. The plant thrives in well-drained, often calcareous soils and is frequently found growing wild on limestone outcrops, dry hillsides, and gravel-rich meadows where competition from taller vegetation is limited.
The genus Veronica was first formally described by Carl Linnaeus in 1753 in his landmark work Species Plantarum. The genus name is traditionally associated with Saint Veronica, though some botanists have suggested it may derive from the Latin 'vera unica,' meaning 'true unique,' in reference to its supposed medicinal virtues. The species name 'spicata' refers to the characteristic spike-like flower clusters that distinguish it from other members of the genus.
Throughout the Middle Ages, various Veronica species were highly valued in European herbal medicine. Herbalists prescribed preparations of speedwell for coughs, digestive troubles, and skin conditions. The common name 'speedwell' itself likely originates from the old English wish of 'speed well' or good health, reflecting the plant's association with healing and well-being. In Germanic folk traditions, the plant was carried by travelers as a protective charm believed to ensure a safe journey.
Spike speedwell entered formal horticultural cultivation in the seventeenth century and quickly became a mainstay of European cottage gardens and herbaceous borders. By the nineteenth century, plant breeders in England and Germany had begun selecting improved forms with larger flower spikes and a wider range of colors. Today, dozens of named cultivars are available commercially, ranging from compact dwarf selections suitable for rock gardens to tall border varieties reaching over 60 cm in height. The species received the Royal Horticultural Society Award of Garden Merit, cementing its status as one of the most reliable and rewarding perennials for temperate gardens worldwide.
