What is Creeping Speedwell?

Creeping speedwell (Veronica filiformis) is a low-growing, perennial ground cover. It spreads rapidly via slender, creeping stems that root at the nodes, making it an effective choice for erosion control or filling gaps in lawns and gardens. However, it can become invasive in some areas due to its aggressive growth habit. It’s often valued for its ability to provide a soft, colorful carpet-like cover in gardens.

Native Area

The perennial is native to Europe and Western Asia.

Creeping speedwell is native to the temperate regions of Europe and Western Asia, particularly in the Caucasus. It thrives in meadows, woodlands, and other open, grassy habitats in its native range, with a cool and moist climate. The plant’s natural distribution includes regions with well-drained soils and moderate rainfall, making it well-suited to thrive in similar conditions worldwide.

Although it is native to these areas, it has been introduced to other parts of the world, including North America and New Zealand, where it is sometimes regarded as an invasive species due to its rapid growth and ability to outcompete native flora.

Characteristics

It is known for its delicate, rounded green leaves and small, pale blue flowers with violet streaks, which bloom in spring and early summer. These blossoms attract pollinators like bees and butterflies. It features slender, creeping stems that root at the nodes, allowing it to create a dense ground cover over time. This plant thrives in various conditions, from full sun to partial shade, and prefers well-drained soil.

Varieties

These tend to be rather durable plants as a whole. There’s multiple species of Veronica, but we’re going to touch briefly on a few of the most popular ones today.

Don’t limit yourself to our recommendations, though! Low-growing varieties like Veronica austriaca or Veronica montana are also beautiful and have similar growth patterns.

Veronica filiformis

This variety prefers to grow in shade with moist, loamy soil.

Veronica filiformis is a type of creeping speedwell that prefers to grow in shade with moist, loamy soil. It has a low mowing height and is typically sold as an ornamental ground cover.

This variety of creeping speedwell spreads by stolons like ground ivy and may grow out of the landscape beds. Veronica filiformis produces blue-violet flowers in the spring. It is also known as slender speedwell and creeping Veronica.

The leaves are very small, opposite and scallop-shaped. Alternate leaves and stems emerge from the base of the plant. The stems root at the nodes and form a fibrous root system that grows rapidly as it spreads in patches. It can become difficult to manage because of its spreading nature. Keep a watchful eye on it to ensure it stays put!

Veronica repens

It has white flowers in late spring and early summer.

Veronica repens is a very popular speedwell variety. It forms small white flowers in the late spring and early summer. This plant’s perfect to plant between paving stones or use as a ground cover for a large area. It can grow in full sun to partial shade.

It can tolerate moderate foot traffic and is tough and versatile in nature. The best time to propagate Veronica repens is spring or early fall. You can easily divide the plant by ripping it apart and planting elsewhere. It can grow well in all types of soil with an average moisture level.

This ground cover has deep green foliage with white flowers. It can grow up to one to two inches in height and spread up to 15 to 30 inches. If you’re looking for a lawn substitute, this variety is among the most popular. It’s lightly drought-resistant, more so if it’s got mulch or compost at the plant bases.

The ‘Sunrise’ variety has brilliant yellow-green foliage and can be quite stunning even without flowers.

Veronica ‘Tidal Pool’

This variety is a hybrid that produces deep blue flowers.

Veronica ‘Tidal Pool’ is a hybrid creeping speedwell that has traits of Veronica armena and Veronica pectinata ‘Rosea’. Developed at the Chicago Botanic Gardens, this hybrid mix of creeping speedwells is dense with fast-spreading capability. It forms vivid green foliage with a silverish tint, and produces deep blue flowers in late April to mid-May.

Veronica ‘Tidal Pool’ makes an attractive ground cover that can survive cold and heat across the year. It can tolerate drought well and can thrive at various humidity levels. ‘Tidal Pool’ averages about two inches tall, with a spread of up to 22″ across.

It can be propagated easily by dividing its clumps in early spring or fall. It has a fast growth rate and will become visually appealing very rapidly.

Planting

Before planting, loosen the soil and remove any weeds to avoid or reduce competition.

Planting creeping speedwell is a straightforward process that begins with selecting a suitable location. Choose a site with well-drained soil and full sun to partial shade, as the plant adapts well to varying light conditions.

To plant, prepare the soil by loosening it and removing weeds to reduce competition. If propagating from established plants, take small divisions with rooted stems or use plugs purchased from a nursery. Place the plants or plugs six to twelve inches apart to allow room for spreading. Gently firm the soil around the roots and water thoroughly after planting to help the plant establish. Once planted, creeping speedwell requires minimal maintenance, though regular watering during the initial weeks helps promote healthy growth. Mulching around the plants can help retain moisture and reduce weed growth.

Over time, the plant will spread and form a lush ground cover.

How to Grow

Creeping speedwell is easy to grow and easy to look after. Its tenacious nature and ability to thrive in any condition makes it easy to grow and care for.

However, you may have to look out for its growth as this perennial can be aggressive in nature. It easily outgrows its landscape area and may enter other spaces via runners. Here’s a breakdown of what you’ll need to do when growing Veronica plants.

Light

The perennial thrives in full sun and partial shades.

Creeping speedwell thrives in full sun and partial shade. While it can grow in complete shade, it doesn’t flower as well there. If you’re in a hot climate, an area with afternoon shade is ideal. Too much blistering sun can cause the plant to wilt.

For people who’re using it as a lawn replacement, it’s perfect if you’ve got partially-shaded conditions under trees. Lots of bright, indirect lighting is fine.

Water

A soaker irrigation system is best for these perennials.

When you newly plant speedwell, it should be watered daily and then reduced gradually with time. Established plants should only be watered when the top inch of soil is dry. Over-watering can create conditions leading to stem and root rot.

Adding a thick layer of compost or mulch when first planting can reduce watering needs. This will provide a barrier against soil moisture evaporation. Once established, water it when the soil begins to dry out for optimal growth.

Soaker hoses hidden underneath the plant’s dense foliage can be used to great effect here. Just be careful not to accidentally prune your hoses when trimming the plant!

Soil

Brown sandy loam soil with a mixture of fine and coarse particles, providing a nutrient-rich foundation for plant growth.
Use a sandy or loamy well-draining soil.

This low-growing perennial is grown in all sorts of soil types. When it has a choice, it prefers either sandy or slightly loamy soil. Well-draining but moisture-retentive soil is best to keep it happy.

Soil pH isn’t a major concern for this plant as long as it’s not heavily acidic or heavily alkaline. Like most ground covers, a neutral soil pH is easiest to maintain, but if you veer slightly to one side or another, it’s okay.

Temperature

This plant prefers cool to mild temperatures.

Creeping speedwell thrives in temperate climates and is well-suited to areas with moderate temperatures. It prefers a cool to mild temperature range, typically flourishing in zones with average daytime temperatures between 50°F to 75°F. This hardy plant can tolerate frost, making it suitable for regions with cold winters. However, it may struggle in extreme heat or prolonged drought conditions, as it prefers moist, well-drained soils and adequate hydration.

In hotter climates, planting creeping speedwell in partial shade can help protect it from heat stress and ensure its continued health and vigor.

Fertilizer

A leaf mold compost will help maintain soil moisture.

Typically, fertilizer isn’t really required for this ground cover. It survives in conditions where other ground covers won’t, including poor soil nutrition scenarios.

To encourage a healthy spread, you can apply an organic fertilizer in the early spring. The higher the phosphorous level, the better flowering, and the light addition of fertilizer will keep the plant happy. If it’s necessary, you can add a second half-strength feeding in mid-summer.

If you’d like to skip a standard fertilizer, work some good compost or leaf mold around the base of the plants in the spring instead. This has the added benefit of keeping the soil moisture consistent.

Don’t over-fertilize this plant. In rich environments, it can rapidly invade other parts of your garden. If you want to set a schedule, the maximum fertilization should be once in early spring and once in early summer. Skip the fall and winter months.

Maintenance

Maintenance can be done by using a mower of deadheading spent flowers.

To maintain the height and shape of the creeping speedwell, you can use a mower in the non-flowering season to trim it down in height. Pruning creeping speedwell after September hinders the new growth and affects the plant’s tendency to wither in the cold temperature, so stop mowing around Labor Day. It will slow its growth through the fall months.

Please be aware that if you’re mowing to prune, it’s best to attach your mower bag. They will readily form new plants from trimmed segments with leaf nodes. A mulching mower may spread these small stem pieces into areas you don’t want the plant to grow!

To encourage more blooming, deadhead spent flowers regularly. You can use lawn shears to snip off clusters of the spent blossoms, but try not to take off too much foliage at the same time.

Propagation

Propagation can be done by its cuttings, division or air-layering techniques.

Veronica-species plants spread via runners under the soil surface. They readily self-propagate in that way. They also form roots at stem nodes, so they are a good choice for cuttings or air layering. Plant division is also an option.

Cuttings can be taken and pressed into moistened potting soil. Be sure a couple of stem nodes are beneath the soil’s surface, and keep them in an area with bright but indirect light until the cuttings take.

It’s possible to root additional plants in place by pressing a stem node underneath the soil’s surface. This is a variation on air layering that works very well with Veronica species.

In colder temperatures, the center of older plants can begin to die out and look brown. Before it begins actively growing again in the spring, it’s a good time to divide your plants. Use a shovel to cut the plant into multiple segments with attached roots, removing the dried-out center. Replant your new starts in the soil, and it will fill out again.

Common Problems

Very few pests and diseases will impact your Veronica plants. They tend to be tough and durable. But let’s discuss the few problems that might arise.

Growing Problems

Too much growth is the biggest issue as it self-propagates very easily.

Probably the biggest growing problem that people encounter isn’t actually a problem with growing it – it’s too much growth! Creeping speedwells are considered weeds in many parts of the United States because they do so well here. Because of this, I do encourage regular pruning in areas you don’t want the speedwell to spread to.

Since it self-propagates by underground runners, using garden edging or barriers that go at least four inches beneath the soil’s surface can also slow growth.

In hotter desert-like climates such as southern California, full sun may cause your plant to wilt in the summer months. This is mostly caused by the soil drying out too rapidly beneath the plant. Water when the plant’s soil is dry in the first inch. Adding mulch or compost around your plants will prevent moisture evaporation.

Pests

There are no reported pests that plague this perennial.

There are no reported pest problems with this perennial, but it can be a haven for some insect species, such as ticks or fleas. Adding beneficial nematodes to your soil will kill off flea and tick eggs and larvae that may be hiding amongst your plants.

Larger animals also tend to leave Veronica-species plants alone. They’re deer-resistant and rabbit-resistant. If you’re in a lightly forested area with partial shade and wild animals, this makes it ideal for you to use as ground cover!

It should be noted that Veronica species are great lures for beneficial insects and pollinators. If you’re trying to develop a pollinator-friendly garden, add a little speedwell for variety.

Diseases

Root rot is a result of overwatering.

Don’t overwater. Too much water creates the conditions that encourage fungal rot diseases to form. Veronica species are susceptible to multiple types of root rot and stem rot, especially if they’re weak already. Try to keep your plants healthy, and the soil evenly moist but not soggy.

Frequently Asked Questions

There are white flowers in my creeping speedwell ground cover. I expected them to be violet-blue. What did I do wrong?

White flowers are produced by Veronica repens. For deep blue varieties, I personally like Veronica filiformis. The ‘Tidal Pool’ hybrid is also an excellent choice for blue blooms. Other Veronica species may produce lilac or baby blue flowers, too!

How often should I fertilize my creeping speedwell?

Rarely if ever. I personally spread some compost among my plants in the early spring, and that provides plenty of nutrition as well as soil moisture retention. If you do want to fertilize, do so in the early spring months. If heat is slowing down its growth mid-summer, you can use a half-strength fertilizer to give it a quick boost again.

I want to plant creeping speedwell but my soil is alkaline. Will it affect the ground cover’s growth?

Lightly-alkaline soils shouldn’t negatively impact your plant’s growth. However, you can improve its chances by working some good composted material into your soil before planting. Once it’s established, an annual application of compost should help bring the soil to a more neutral pH level.

Can you walk on creeping speedwell?

You certainly can! The plant can handle foot traffic like a pro.

Is creeping speedwell evergreen?

It is, indeed, an evergreen plant.

Is creeping speedwell invasive?

In most parts of North America, Veronica species, are simply non-native annual weeds. However, in Alaska and West Virginia, the plant is classed as an invasive species.
