The Best Low Maintenance Flowers for a UK Garden

The Best Low Maintenance Flowers for a UK Garden

Andrew Rocks · 6 August 2026

The best low maintenance flowers for a UK garden: RHS award-winning picks for sun, shade and pollinators, plus when to plant them.

The best low maintenance flowers do more than survive a dry summer, they still look good doing it. After a summer like this one, the plants worth having are the ones that cope on the least water and the least time. Here's where to start.

Top 10 Low Maintenance Flowers

Plant

Best for

Why it earns its place

Lavender 'Hidcote'

Full sun, pollinators

Blooms for months, rarely gets straggly

Nepeta 'Six Hills Giant' (catmint)

Full sun, pollinators

Flowers June to first frost, even left alone

Erysimum 'Bowles's Mauve' (perennial wallflower)

Full sun

In flower almost year-round

Erigeron karvinskianus (Mexican fleabane)

Sun, gaps and paving

Self-seeds and needs nothing from you

Geranium macrorrhizum 'Ingwersen's Variety'

Shade, ground cover

Dies back and tidies itself up

Helleborus 'Walberton Rosemary'

Flowers from Christmas to May, barely touched

Salvia microphylla 'Cerro Potosí'

Thalictrum 'Elin'

Cut back once a year, that's it

Osteospermum jucundum

Full sun

Hardy, and you can propagate it by pushing a stem into soil

Rosa Flower Carpet White

Full sun

Low, vigorous rose, one light annual trim

Every plant on that list carries the RHS Award of Garden Merit, which means it's been trialled and shown to perform reliably in ordinary UK garden conditions, not just in a nursery pot.

What we mean by "low maintenance"

Some flowers hold traits that make them low maintenance some of the main traits are:

  • Drought tolerant once it's settled in, not just while someone's watering it
  • Naturally disease resistant, so you're not reaching for sprays
  • A growth habit that doesn't need staking or constant cutting back
  • Minimal deadheading required to keep flowering

Bedding plants that need replacing twice a year, and roses that demand regular feeding and spraying, fail that test even though they're popular. There's nothing wrong with them, they're just not what this list is about.

For shady spots



Shade doesn't have to mean bare soil:

  • Geranium macrorrhizum, ground cover that flowers in June and July and needs no cutting back
  • Helleborus, in flower from the depths of winter into spring
  • Astilbe, good for damp, shady corners near water features
  • Heuchera, grown mainly for foliage colour but a reliable low-light filler

For pollinators



Look out for the RHS Plants for Pollinators label when you're buying, it's based on the RHS's own research into what bees, butterflies and hoverflies actually use. Lavender, catmint, salvia and Mexican fleabane, all in the quick picks above, carry it.

When to plant

Most hardy perennials go in during two windows: March to May, or September to October, when the soil's workable and not baking hot or frozen solid. Bare-root roses are best planted while dormant over winter. Container-grown plants are more forgiving and can generally go in whenever the ground isn't frozen or waterlogged.

Low Maintenance. Not, No Maintenance...

Low maintenance doesn't mean no maintenance in year one. Even the toughest plants on this list need watering in properly through their first season while the roots establish, the same point we made about new turf in our recent piece on lawn drought recovery. Get that first year right, and most of these will genuinely look after themselves from then on.
