8 Low Maintenance Hardy Perennials for UK Gardens (Easy-Care & Colourful)
Why These Low Maintenance Hardy Perennials Belong in Every UK Garden
If you want a beautiful garden but don’t have endless hours for weeding, pruning, and watering, then low-maintenance hardy perennials are your best friends. These are the plants that come back every year, thrive with minimal fuss, and still deliver colour, structure, and even fragrance across the seasons.
For UK gardeners, hardy perennials are particularly valuable because they’re tough enough to handle cold winters, unpredictable rainfall, and spells of drought in summer. Once established, they save time, money, and effort, while providing maximum impact.
In this guide, we’ll explore eight of the very best hardy perennials for low-maintenance UK gardens, with growing tips on position, soil, and maintenance for each. Whether you’re a complete beginner or a seasoned gardener looking to simplify, these plants will give you a resilient, wildlife-friendly, and stylish garden without constant work.
1. Lavender (Lavandula angustifolia) — Fragrance and Pollinator Appeal
Low Maintenance Hardy Perennials – Lavender is a household favourite.
Few plants say “summer in Britain” like lavender plants. Its violet blooms, grey-green foliage, and heavenly fragrance make it a staple in cottage gardens, contemporary landscapes, and containers. Lavender is a magnet for bees and butterflies, while its resilience makes it a superb low-maintenance choice.
Position
Lavender thrives in full sun, ideally a south – or west-facing spot that gets six or more hours of direct sunlight. It also performs well in coastal gardens, coping with salty winds that challenge more delicate plants.
Soil
This perennial loves free-draining soil. Heavy clay that holds water can cause root rot, so improve such soils with horticultural grit or sand before planting. Raised beds or containers are also excellent options.
Maintenance
Water sparingly once mature. The main task is pruning in late summer after flowering—cutting back flower stalks and leafy growth to keep a neat shape. Avoid cutting into woody stems, which don’t regenerate.
Why it’s low maintenance: Drought tolerant, pest resistant, long-lived, and highly ornamental.
2. Sedum ‘Autumn Joy’ (Hylotelephium herbstfreude) — Reliable Late-Summer Colour
Low Maintenance Hardy Perennials – Sedum are tough, tough, tough perennial plants for the UK.
Sedum, or stonecrop plants, are one of the toughest perennials available. Its fleshy leaves withstand drought, while its pink-to-bronze flower heads provide colour from late summer into autumn.
Position
Best in full sun, but tolerates light shade. Ideal for borders, gravel gardens, or even green roofs.
Soil
Sedum thrives in poor, free-draining soils. It actually prefers nutrient-lean conditions where many perennials struggle.
Maintenance
After its first season, Sedum requires almost no attention. Water only in severe drought. In spring, cut back last year’s dried stems to allow fresh growth through.
Why it’s low maintenance: Near-indestructible, self-sufficient, and colourful when many other plants fade.
3. Hardy Geraniums (Geranium Rozanne and others) — Long-Flowering Groundcover
Low Maintenance Hardy Perennials – Cranesbill has a long flowering period.
Cranesbill geraniums are generous bloomers, with many varieties flowering from May until the first frost. Unlike tender pelargoniums, hardy geraniums are perennial and come back year after year.
Position
Adaptable to both sun and partial shade. They’re excellent for edging paths, filling gaps in borders, or spilling over walls.
Soil
Happy in most UK soils, including clay, provided it’s not waterlogged. Adding compost helps new plants establish faster.
Maintenance
Almost maintenance-free. Deadheading promotes more flowers, but it’s optional. Cutting back midsummer can encourage a second flush of blooms.
Why it’s low maintenance: Long bloom period, adaptable to conditions, and excellent weed suppressors.
4. Echinacea (Coneflower) — Pollinator Magnet
Low Maintenance Hardy Perennials – Coneflower is another popular plant amongst gardeners.
Echinacea is a daisy-like perennial with bold purple, pink, or white blooms. It’s beloved by pollinators and provides seeds for birds in winter.
Position
Prefers sunny spots, but tolerates light shade. Ideal for wildlife gardens or naturalistic borders.
Soil
Well-drained soil is essential. Light sandy or loamy soils are best, though clay can be improved with grit and compost.
Maintenance
Minimal. Deadhead to extend flowering or leave seed heads for birds. Cut back dead stems in late winter before new growth.
Why it’s low maintenance: Highly resilient, drought tolerant, and attractive to wildlife.
5. Catmint (Nepeta faassenii) — Aromatic and Long-Flowering
Low Maintenance Hardy Perennials – Catmint, butterflies and bees will love you for planting this low maintenance hardy perennial.
Catmint is a long-flowering perennial with grey foliage and lavender-blue blooms. It’s loved by pollinators and adds a relaxed, cottage-style look to borders.
Position
Prefers full sun but grows well in partial shade. Ideal for lining borders, softening edges, or mass planting.
Soil
Needs free-draining soil, especially sandy or chalky types. It dislikes heavy, wet conditions
Maintenance
Minimal. Cut back after the first flowering to encourage a second flush. Otherwise, it needs only occasional watering during long dry spells.
Why it’s low maintenance: Flowers for months, tolerates poor soils, and requires very little attention.
6. Yarrow (Achillea millefolium) — Tough Meadow-Style Plant
Low Maintenance Hardy Perennials – Yarrow is a fantastic plant for wildlife.
Yarrow is UK native wildflower that’s also a garden favourite, yarrow provides flat clusters of flowers in various colours, with a feathery foliage.
Position
Sun-loving, suited to open borders, cottage gardens, and wildlife plantings.
Soil
Thrives in poor, sandy, or stony soils. Avoid overly rich soil, which produces weak, floppy growth.
Maintenance
Tough and forgiving. Deadhead for repeat blooms, divide clumps every few years to keep plants strong.
Why it’s low maintenance: Hardy, pest resistant, and brilliant for bees and butterflies.
7. Russian Sage (Perovskia atriplicifolia) — Airy and Architectural
Low Maintenance Hardy Perennials – If your soil is chalky or sandy its the perennial for you.
Russian sage brings texture and movement with its airy sprays of violet-blue flowers and silvery stems.

Deadheading prolongs flowering. In mild areas, it self-seeds readily, providing free plants the following year.
