A Guide to English Garden Flowers

The English garden is renowned worldwide for its romantic, naturalistic style and abundant flowering displays. From the informal cottage garden bursting with hollyhocks and delphiniums to the structured herbaceous borders of grand estates, English gardens showcase an extraordinary variety of flowering plants that thrive in Britain’s temperate maritime climate.

Spring Flowers (March – May)

Daffodils (Narcissus)

The quintessential spring flower, daffodils naturalize beautifully in grass and woodland areas. Varieties range from the classic yellow trumpet daffodil to delicate white and cream cultivars. Plant bulbs in autumn for spring displays that multiply year after year.

Tulips (Tulipa)

While originally from Turkey, tulips have become garden staples. Darwin hybrids and cottage tulips work particularly well in English gardens, providing bold splashes of color in borders and containers from April through May.

Primroses (Primula vulgaris)

These delicate native wildflowers carpet woodland floors and shaded borders with pale yellow blooms. Modern cultivars offer colors from white to deep purple, all sharing the characteristic five-petaled flowers.

Wallflowers (Erysimum)

Fragrant and long-flowering, wallflowers are perfect for cottage gardens. Their spicy-sweet scent and rich colors—from cream to deep burgundy—make them invaluable for spring borders.

Forget-me-nots (Myosotis)

These charming blue flowers self-seed freely, creating drifts of color beneath taller plants. White and pink varieties are also available, all equally good for naturalizing.

Early Summer Flowers (June – July)

Roses (Rosa)

No English garden is complete without roses. English roses bred by David Austin combine the fragrance and form of old roses with modern repeat-flowering. Climbing roses on walls and arbors, shrub roses in borders, and rambling roses through trees all have their place.

Peonies (Paeonia)

These sumptuous flowers are long-lived perennials that improve with age. Herbaceous peonies die back in winter, while tree peonies form woody shrubs. Both offer spectacular, often fragrant blooms in late spring and early summer.

Irises (Iris)

Bearded irises are particularly popular, with their architectural flowers and sword-like foliage. They prefer sunny, well-drained positions and come in almost every color except true red.

Aquilegia (Columbine)

These graceful flowers with their distinctive spurred petals self-seed readily, creating natural drifts. They’re perfect for cottage gardens and woodland areas, flowering in early summer.

Lupins (Lupinus)

Tall spikes of pea-like flowers in jewel tones make lupins spectacular border plants. They prefer slightly acidic soil and benefit from cutting back after flowering to encourage a second flush.

High Summer Flowers (July – August)

Delphiniums (Delphinium)

These majestic plants produce towering spikes of blue, purple, pink, or white flowers. They’re quintessential English garden plants but require staking and rich, moist soil to perform well.

Hollyhocks (Alcea rosea)

Tall, architectural plants perfect for cottage gardens and against walls. Their papery flowers attract bees and butterflies, and they self-seed readily. Watch for rust disease on older plants.

Lavender (Lavandula)

Fragrant and drought-tolerant, lavender is essential for sunny borders. English lavender (L. angustifolia) is hardiest, while French lavender offers more exotic flower forms.

Catmint (Nepeta)

These hazy blue or purple flowers are bee magnets and complement roses beautifully. They’re drought-tolerant once established and benefit from cutting back mid-season.

Geraniums (Geranium)

Hardy geraniums (not to be confused with pelargoniums) are invaluable ground cover plants. They flower for months and many have good autumn color.

Late Summer to Autumn Flowers (August – October)

Dahlias (Dahlia)

These tender perennials provide spectacular late summer color. From dinner-plate sized blooms to delicate pompons, dahlias come in every color except blue. Lift tubers in areas with hard frosts.

Chrysanthemums (Chrysanthemum)

Traditional autumn flowers ranging from button sprays to large exhibition blooms. Korean and rubellum types are particularly hardy for outdoor growing.

Asters (Symphyotrichum)

Michaelmas daisies provide vital late nectar for butterflies and bees. They prefer moist conditions and benefit from division every few years to maintain vigor.

Sedum (Hylotelephium)

These succulent perennials produce flat heads of pink flowers that attract butterflies. Their fleshy leaves and architectural form provide year-round interest.

Japanese Anemones (Anemone hupehensis)

These elegant late-flowering perennials produce pink or white flowers on tall stems. They can be invasive but are perfect for naturalizing in woodland gardens.

Classic English Garden Combinations

Cottage Garden Style

  • Combine hollyhocks, delphiniums, and roses as backbone plants
  • Fill gaps with self-seeding annuals like nigella, calendula, and sweet peas
  • Edge paths with lavender, catmint, or lady’s mantle

Herbaceous Border

  • Plant in drifts of odd numbers (3, 5, 7 plants)
  • Use tall plants like delphiniums and hollyhocks at the back
  • Middle layer: peonies, irises, and day lilies
  • Front edge: hardy geraniums, lamb’s ear, and low-growing sedums

Woodland Garden

  • Focus on spring bulbs and shade-tolerant perennials
  • Combine hellebores, pulmonarias, and ferns
  • Add structure with shrubs like rhododendrons and camellias

Growing Tips

Soil Preparation

Most English garden flowers prefer well-drained, fertile soil. Add compost annually and ensure good drainage, especially for Mediterranean plants like lavender.

Planting Times

  • Spring bulbs: Plant in autumn
  • Summer perennials: Plant in spring or autumn
  • Tender plants: Plant after last frost

Maintenance

  • Deadhead regularly to extend flowering
  • Divide perennials every 3-4 years
  • Mulch annually with compost or well-rotted manure
  • Water deeply but infrequently once established

Seasonal Care

  • Spring: Plant, divide, and feed
  • Summer: Water, deadhead, and stake tall plants
  • Autumn: Plant bulbs, cut back perennials, lift tender plants
  • Winter: Protect tender plants, plan next year’s garden

Wildlife Benefits

English garden flowers support local wildlife:

  • Bees love lavender, catmint, and single-flowered varieties
  • Butterflies prefer flat-headed flowers like sedums and asters
  • Birds enjoy seed heads left standing through winter
  • Native plants like primroses support specialist insects

Conclusion

The beauty of an English garden lies in its seeming naturalness—carefully orchestrated combinations that appear to have evolved organically. By choosing plants suited to your soil and climate, providing good growing conditions, and allowing for some self-seeding and naturalization, you can create a garden that captures the timeless appeal of the English gardening tradition.

Whether you’re creating a small cottage garden or planning extensive herbaceous borders, these flowers will provide the backbone of a truly English garden that offers beauty, fragrance, and wildlife value throughout the growing season.
