The Best Ground Cover Plants for Irish and European Gardens: Cotoneaster, Geranium & More
The best ground cover plants for Irish and European gardens are Cotoneaster dammeri, Geranium macrorrhizum, and Leptinella squalida — all frost-hardy, low-maintenance, and well-suited to Ireland's Atlantic climate. Ground cover plants suppress weeds, prevent soil erosion on banks and slopes, and dramatically reduce the time you spend maintaining borders. This guide covers six of the best varieties available in bulk packs of 60 plants from €127.95, with delivery throughout Ireland and across the EU.
A single square metre of well-established Cotoneaster ground cover can suppress weed growth by up to 90%, according to horticultural research on dense-canopy shrub planting. By blocking light from reaching the soil surface, ground cover plants eliminate the conditions that allow most annual weeds to germinate — reducing or eliminating the need for herbicides entirely.

In Ireland's mild, wet Atlantic climate, the most reliable performers are Cotoneaster dammeri (and related prostrate varieties), Geranium macrorrhizum (the Bigroot Geranium), and Leptinella squalida (New Zealand Brass Buttons). Each fills a different niche: Cotoneaster excels on slopes and open ground; Geranium macrorrhizum is the go-to for shaded and dry positions; Leptinella is ideal for pathways and planting between paving stones.
All six varieties available from PlantGift.ie are supplied in 9cm pots at 10–25cm height, ready to plant directly into prepared ground. They are packaged in bulk packs of 60 plants — the most cost-effective way to cover a large area, a bank, or a commercial landscaping project.

Which Cotoneaster Varieties Are Best for Ground Cover?
🌿 Featured Ground Cover Bulk Packs
Top picks from this guide — pre-curated bulk packs delivered across Ireland & EU.
The three best Cotoneaster varieties for ground cover in Irish gardens are Cotoneaster dammeri 'Major', Cotoneaster prostratus 'Queen of Carpets', and Cotoneaster suecicus 'Coral Beauty' — all low-growing, spreading shrubs that hug the ground and spread 1–2 metres wide over two to three seasons. These varieties produce white flowers in spring (a valuable early nectar source for pollinators) and colourful berries in autumn and winter that provide food for blackbirds, redwings, and other garden birds throughout the colder months. All three are fully evergreen and frost-hardy to well below -15°C, making them an excellent fit for Irish conditions from Donegal to Cork.
Cotoneaster dammeri 'Major' is the most vigorous of the three, hugging close to the ground and spreading rapidly. It is particularly effective on sloped ground and banks where erosion control is a priority. Cotoneaster prostratus 'Queen of Carpets' forms a flat, prostrate mat that is slightly more compact, with white flowers in May and red berries appearing from November. Cotoneaster suecicus 'Coral Beauty' offers a distinctive ornamental touch with its striking orange-red berries in autumn — a favourite for wildlife-friendly landscaping schemes and one of the most widely planted Cotoneaster varieties across Europe.

How Do You Use Geranium Macrorrhizum as Ground Cover?
Geranium macrorrhizum, the Bigroot Geranium, is one of the most effective herbaceous ground covers for Irish gardens — particularly in partially shaded or dry positions where other plants struggle. It spreads via thick, aromatic underground rhizomes (hence "macrorrhizum" — big root), forming a dense, weed-suppressing mat 30–40cm tall with attractive, semi-evergreen foliage that takes on red and orange tints in autumn. Flowers appear in spring, typically April to June, in shades of pink to magenta depending on the variety.
To use Geranium macrorrhizum as ground cover, plant at 30cm spacings (approximately 9–11 plants per square metre for quick coverage, or 4–6 per square metre for a more economical planting that fills in over two seasons). It requires minimal maintenance once established — cut back the old foliage in late February or early March before new growth begins. Geranium macrorrhizum 'Czakor' is the standout pollinator variety, producing deep pink to magenta flowers that are a magnet for bees throughout spring and early summer. Its autumn colour — rich orange-red foliage — is also superior to the straight species, making it excellent value for money in an ornamental border as well as a purely functional ground cover planting.

Geranium macrorrhizum 'Czakor' — Deep Pink Hardy Ground Cover (60 Plants)
Geranium macrorrhizum 'Czakor' produces flowers rich in pollen and nectar from April through June — one of the most important foraging periods for bumblebees emerging from winter hibernation. Planting a 60-plant block of 'Czakor' provides a substantial, sustained nectar source that supports local pollinator populations throughout spring. Ireland's All-Ireland Pollinator Plan specifically recommends mass plantings of native and near-native Geranium species in public landscaping schemes.
What Is Leptinella Squalida and Where Does It Grow?
Leptinella squalida, commonly called Brass Buttons or Lawn Chamomile, is a low-growing New Zealand native that forms a dense, feathery, fern-like mat only 2–5cm tall — making it one of the flattest true ground covers available. It is fully frost-hardy (rated to -15°C or below) and perfectly suited to Ireland's cool, moist Atlantic climate, where it remains evergreen year-round. Unlike most ground covers, Leptinella squalida tolerates light foot traffic, which makes it an excellent choice for planting between stepping stones, along pathways, and in paved courtyard gardens where a plant that can handle occasional footfall is needed.
Its spreading habit is dense enough to suppress weeds effectively, and its tiny, button-like yellow flowers appear in late spring, adding gentle seasonal interest without overwhelming the planting. Leptinella squalida grows in both sun and shade, though it prefers a position with at least partial light and consistently moist soil — conditions that are easily met across most of Ireland. Plant at 30cm spacings for full coverage within two seasons, or at 20cm spacings for faster establishment in high-visibility areas.

How Many Ground Cover Plants Do You Need Per Square Metre?
For most ground cover plants, you will need 4–6 plants per square metre for coverage that fills in fully within two to three seasons, or 9–11 plants per square metre if you want dense coverage within a single growing season. The right density depends on your budget, the size of the area, and how quickly you need coverage.
As a practical guide for the plants covered in this article:
- Cotoneaster dammeri, 'Queen of Carpets', 'Coral Beauty': Plant at 30–40cm spacings = 6–9 plants per m². At 40cm spacings, a pack of 60 covers approximately 9–10 m². At 30cm spacings, 60 plants cover approximately 5–6 m².
- Geranium macrorrhizum and 'Czakor': Plant at 30cm spacings = approximately 9–11 plants per m². A 60-plant pack covers 5–6 m² at this density, forming a weed-proof mat by mid-summer of the first year.
- Leptinella squalida: Plant at 20–30cm spacings = 9–25 plants per m². For pathway and stepping stone use, 20cm spacings give the quickest coverage. A 60-plant pack covers 2.5–6 m² depending on spacing.

What Are the Best Ground Cover Plants for Slopes and Banks?
The best ground cover plants for slopes and banks in Irish gardens are Cotoneaster varieties — specifically Cotoneaster dammeri 'Major' and Cotoneaster prostratus 'Queen of Carpets'. Their woody, spreading stems anchor firmly into soil and interlock as they grow, creating a living mesh that holds the soil in place and prevents erosion on gradients of up to approximately 45 degrees. This makes them a practical and attractive alternative to jute netting, bark mulch, or other erosion-control methods that require regular replacement.
For slopes, plant Cotoneaster at 4–6 plants per square metre (30–40cm spacings), positioning plants slightly offset from each other in a staggered grid rather than straight rows. This ensures maximum root contact with the soil across the slope. Water thoroughly in the first season, particularly during dry spells in May, June, and September — the months most likely to see moisture stress even in Ireland. Once established (usually by the end of the second season), Cotoneaster is remarkably drought-tolerant and will require no irrigation at all.
Geranium macrorrhizum is an excellent secondary choice for shaded slopes and north-facing banks, where Cotoneaster's preference for sun or partial shade may be a limiting factor. Its spreading rhizomes bind soil effectively and its dense canopy prevents rain from directly impacting the soil surface — a key mechanism in erosion control.
