Sunny gardens are full of colour, fragrance, texture, and life. In Metro Vancouver and the Pacific Northwest, a well-planted sunny border can provide flowers from spring through fall, attract pollinators, and return year after year with the right care. Sun loving perennials are especially useful because they give gardeners long term value. Once established, many of them become dependable plants that need less replanting than annuals and can form the backbone of a beautiful garden bed.
When we talk about sun loving perennials, we usually mean plants that perform best with at least six hours of direct sun per day. Some will tolerate part shade, but most bloom better, grow stronger, and stay more compact when they receive enough sunlight. In too much shade, many sun perennials stretch, flop, bloom less, or become more prone to disease.
In our coastal climate, the biggest challenge is often not summer heat, but winter wet. Metro Vancouver gardens can receive plenty of rain through fall, winter, and spring. Plants such as Lavender, Agastache, Dianthus, Red Hot Poker, Iris, Gaillardia, and Upright Sedums need good drainage to thrive. If they sit in heavy, soggy soil through winter, they may decline or fail to return well the following spring.
That does not mean sun loving perennials are difficult. It simply means the right plant should be matched to the right place. Some plants love lean, dry, sunny conditions. Others prefer sun with richer soil and more consistent moisture. A little planning makes a big difference.
The following are twenty of our favourite sun loving perennials for Pacific Northwest gardens. They are sorted alphabetically and include a mix of long blooming perennials, pollinator favourites, classic garden plants, fragrant choices, drought tolerant performers, and late season colour providers.
Before You Plant
Start by observing your garden through the day. A true full sun location receives at least six hours of direct sun. Morning sun is gentler, while afternoon sun is stronger and warmer. Many of these perennials will be happiest in open, bright locations where air can move freely around the plants.
Next, check your soil. If water sits in the planting area after rain, improve drainage before planting plants that dislike winter wet. Raised beds, mounded planting areas, and compost improved soil can all help. For plants that prefer leaner conditions, avoid adding too much fertilizer or rich organic matter. Overly rich soil can cause soft, floppy growth on plants like Achillea, Sedum, Russian Sage, and Lavender.
During the first growing season, water deeply while plants establish. Even drought tolerant perennials need regular water when newly planted. Once roots grow into the surrounding soil, many sun perennials become much more resilient.
Our Favourite 20 Sun Loving Perennials
Achillea
Achillea spp., Yarrow
Achillea, commonly called Yarrow, is a tough sun perennial with flat topped flower clusters and fine textured foliage. Flower colours include white, yellow, pink, red, orange, and soft pastel blends. It grows best in full sun and well drained soil. Yarrow is useful in pollinator gardens, dry borders, meadow style plantings, and cottage gardens. It does not need rich soil and may flop if the soil is too fertile or too wet. Deadheading can encourage additional bloom and keep the plant looking tidy.
Agastache
Agastache spp., Hyssop or Hummingbird Mint
Agastache is a fragrant, pollinator friendly perennial with upright flower spikes and aromatic foliage. Depending on the variety, flowers may be blue, purple, pink, orange, peach, or coral. It grows best in full sun and very well drained soil. Good drainage is especially important through winter. Agastache is excellent for bees, butterflies, and hummingbirds, and it works beautifully in sunny borders, herb gardens, and low water plantings. Avoid heavy wet clay and avoid over fertilizing.
Coreopsis
Coreopsis spp., Tickseed
Coreopsis is a bright, cheerful perennial known for long blooming flowers in yellow, gold, red, pink, or bicolour forms. It is excellent in sunny borders, pollinator gardens, containers, and lower maintenance plantings. Most Coreopsis prefer full sun and well drained soil. Many varieties tolerate dry conditions once established. Deadheading can encourage continued bloom, although some modern varieties flower well with minimal care. Avoid wet winter soil, which can reduce plant longevity.
Daylilies
Hemerocallis spp., Daylily
Daylilies are dependable and adaptable perennials with grassy foliage and trumpet shaped flowers. Each flower usually lasts one day, but mature plants produce many buds over the season. Daylilies flower best in full sun, although they can tolerate part shade. They grow in a wide range of well drained soils and appreciate deep watering during dry weather. Remove spent flower stalks after bloom and divide older clumps when they become crowded or produce fewer flowers.
Dianthus
Dianthus spp., Pinks
Dianthus are compact perennials known for fragrant flowers and neat blue green or grey green foliage. Flowers may be pink, red, white, or bicolour, often with fringed petals. Dianthus grows best in full sun with well drained soil. Good drainage is especially important in winter because wet soil can cause crown problems. These plants are excellent for edging, rock gardens, containers, sunny borders, and cottage garden plantings. Deadhead spent flowers to encourage repeat bloom where varieties allow.
Echinacea
Echinacea spp., Coneflower
Echinacea is a strong summer blooming perennial with daisy like flowers and raised central cones. It is best known in shades of pink and purple, but modern varieties also come in white, yellow, orange, red, and green toned forms. Echinacea grows best in full sun to part shade with well drained soil. Once established, it has good drought tolerance and is excellent for pollinator gardens. Leave some seed heads standing into fall if you want to support birds and add winter texture.
Gaillardia
Gaillardia spp., Blanket Flower
Gaillardia is a bright, cheerful perennial with daisy like flowers in warm shades of red, orange, yellow, and burgundy. It is a good choice for sunny borders, dry gardens, containers, and pollinator plantings. Gaillardia needs full sun and well drained soil. It performs poorly in heavy wet clay, especially in winter. Some varieties can be short lived, but they provide excellent colour and can bloom for a long period when happy.
Hardy Geraniums
Geranium spp., Cranesbill
Hardy Geraniums are long lived garden perennials that should not be confused with annual bedding geraniums, which are actually Pelargonium. Hardy Geraniums produce mounding foliage and saucer shaped flowers in shades of blue, purple, pink, or white. Many varieties grow well in full sun to part shade, although the best location depends on the cultivar. In sunny sites, they appreciate well drained soil and regular moisture. Some can be cut back after flowering to encourage fresh foliage and possible rebloom.
Iris
Iris germanica and related types, Iris
Bearded Iris are dramatic spring and early summer bloomers with upright sword shaped foliage and colourful flowers. They need full sun for best bloom and disease resistance. Good drainage is essential because rhizomes can rot in wet soil. Plant bearded iris rhizomes shallowly, with the top of the rhizome near the soil surface. Avoid heavy mulch directly over the rhizomes. Divide clumps when flowering declines or the centre becomes crowded.
Lavender
Lavandula spp., Lavender
Lavender is loved for its fragrance, silvery foliage, and purple flower spikes. It is a classic choice for sunny borders, dry gardens, herb gardens, containers, and pollinator plantings. Lavender needs full sun and very good drainage. It does not like wet winter soil or heavy mulch around the crown. In Metro Vancouver, plant it in a warm, open site with airflow. Prune lightly after flowering or in spring to maintain shape, but avoid cutting hard into old woody stems.
Monarda
Monarda spp., Bee Balm
Monarda is a colourful perennial with shaggy flower heads that attract bees, butterflies, and hummingbirds. Flowers may be red, pink, purple, lavender, or white. Monarda grows best in full sun to light shade and rich, evenly moist, well drained soil. It is not as drought tolerant as Lavender or Yarrow and should not be allowed to dry severely. Good airflow is important because some varieties are prone to powdery mildew. Choose mildew resistant varieties when possible and avoid overhead watering.
Nepeta
Nepeta spp., Catmint
Nepeta is a soft, easy growing perennial with aromatic grey green foliage and long blooming blue lavender flowers. It is excellent along pathways, around roses, in pollinator gardens, and at the front of sunny borders. Nepeta grows best in full sun to part shade and well drained soil. Many varieties are drought tolerant once established. After the first major bloom, shear plants lightly to refresh the foliage and encourage more flowers.
Peonies
Paeonia spp., Peony
Peonies are long lived perennials with large, showy flowers in late spring to early summer. They are available in herbaceous, tree, and Itoh types, but herbaceous peonies are the classic garden form. Peonies grow best in full sun and rich, fertile, well drained soil. They dislike being moved once established, so choose the planting site carefully. In fall, cut herbaceous peony foliage to the ground and remove it from the garden to reduce disease carryover.
Red Hot Poker
Kniphofia spp., Red Hot Poker
Red Hot Poker is a bold perennial with upright spikes of tubular flowers in red, orange, yellow, cream, or bicolour combinations. It adds strong vertical form to sunny beds and is attractive to hummingbirds and bees. Kniphofia grows best in full sun with well drained soil that is not too wet in winter. Plant it where drainage is sharp and airflow is good. Remove spent flower spikes and avoid disturbing established clumps unless division is needed.
Rudbeckia
Rudbeckia spp., Black Eyed Susan
Rudbeckia brings cheerful yellow and gold flowers from summer into fall. It is one of the easiest perennials for adding bold colour to sunny beds. Rudbeckia grows best in full sun and average, well drained soil. Established plants tolerate some dry conditions, although they look best with steady moisture during bloom. Rudbeckia is excellent in mixed borders, pollinator gardens, cottage gardens, and late summer displays. Deadheading can tidy the plant and encourage more flowers, but seed heads can also be left for birds.
Russian Sage
Salvia yangii, formerly Perovskia atriplicifolia
Russian Sage is a tough sun perennial with silvery stems, aromatic foliage, and airy blue violet flowers. It is excellent for dry sunny borders, pollinator gardens, and low water landscapes. Russian Sage grows best in full sun and well drained soil. Rich soil or too much shade can make it floppy. Cut it back in late winter or early spring before new growth begins. It pairs beautifully with Echinacea, Rudbeckia, Sedum, ornamental grasses, and Yarrow.
Salvia
Salvia spp., Perennial Sage
Perennial Salvia is a reliable choice for sunny borders and pollinator gardens. Flower spikes may be blue, purple, pink, white, or violet depending on the variety. Most perennial salvias prefer full sun and well drained soil. Once the first flush of flowers fades, shearing or deadheading can encourage a second show. Salvia is useful for edging, mass planting, cottage gardens, and mixing with Lavender, Nepeta, Coreopsis, and ornamental grasses.
Shasta Daisy
Leucanthemum x superbum, Shasta Daisy
Shasta Daisies are classic summer perennials with white petals and yellow centres. They bring a fresh, cheerful look to sunny borders and cottage gardens. Shasta Daisies grow best in full sun and well drained soil. Wet winter soil can be a problem, so avoid planting them where water sits. Deadheading encourages a tidier plant and may extend bloom. Divide clumps every few years to maintain vigour and reduce crowding.
Upright Sedums
Hylotelephium spp., including Autumn Joy Stonecrop
Upright Sedums are excellent late season perennials with succulent foliage and broad flower heads that attract pollinators. Varieties like Autumn Joy are especially valued for late summer and fall colour. They grow best in full sun and dry to medium, well drained soil. Avoid overly rich soil, excess watering, or too much shade, as these can cause weak, floppy growth. Leave the dried flower heads standing for winter interest, then cut back in early spring.
Veronica
Veronica spp., Speedwell
Veronica is a tidy perennial with upright flower spikes in blue, purple, pink, or white. It is useful in sunny borders, pollinator plantings, and mixed perennial beds. Veronica grows best in full sun with well drained soil and regular moisture. It has shallow roots and can struggle if allowed to dry too much during active growth. Remove spent flower spikes to encourage more bloom and cut back after flowering if the plant needs refreshing.
Care and Advice for Success
Give them enough sun
Most sun loving perennials need at least six hours of direct sun for best bloom, strong stems, and healthy growth. If they receive too much shade, they may stretch, flop, bloom less, or develop more disease issues. For the brightest flower display, choose an open, sunny location with good airflow.
Focus on drainage
Good drainage is one of the most important success factors in Metro Vancouver gardens. Our wet winters can be hard on plants that come from drier or more open habitats. Lavender, Iris, Dianthus, Agastache, Sedum, Gaillardia, and Red Hot Poker are especially sensitive to wet winter soil. If drainage is poor, raise the planting area or choose plants that tolerate more moisture.
Water deeply during the first year
Drought tolerant does not mean drought proof at planting time. Newly planted perennials need deep watering while they establish. Water thoroughly, then allow the soil to begin drying before watering again. This encourages deeper roots and stronger plants.
Deadhead when useful
Deadheading means removing spent flowers. It keeps plants looking tidy and can encourage more blooms on plants such as Salvia, Nepeta, Gaillardia, Shasta Daisy, Veronica, Coreopsis, Dianthus, and Monarda. For plants with ornamental seed heads, such as Echinacea, Rudbeckia, and Sedum, you may choose to leave some flowers standing for fall and winter interest.
Do not overfeed
Many sun loving perennials perform better in average soil than in very rich soil. Too much fertilizer can create soft, floppy growth, especially on Sedum, Yarrow, Russian Sage, Lavender, and Agastache. Compost at planting time is usually enough for many of these plants unless your soil is very poor.
Divide when clumps become crowded
Some perennials benefit from division every few years. Daylilies, Shasta Daisies, Iris, Hardy Geraniums, and some Coreopsis may bloom better after crowded clumps are divided. Spring or early fall is often a good time, depending on the plant and weather.
Designing With Sun Loving Perennials
For a long season of colour, combine early bloomers, summer bloomers, and late season plants. Peonies and Iris provide spring to early summer interest. Lavender, Salvia, Nepeta, Shasta Daisy, Coreopsis, Monarda, Veronica, Daylilies, and Gaillardia carry the garden through summer. Echinacea, Rudbeckia, Upright Sedums, Russian Sage, Agastache, and Achillea extend colour into late summer and fall.
For a pollinator garden, combine Achillea, Agastache, Coreopsis, Echinacea, Gaillardia, Lavender, Monarda, Nepeta, Rudbeckia, Salvia, and Veronica. Use repeated groups rather than one of everything. Repetition makes the garden look more intentional and helps pollinators find flowers more easily.
For a lower water sunny border, focus on Achillea, Agastache, Gaillardia, Lavender, Nepeta, Russian Sage, Upright Sedums, and some Coreopsis. Improve drainage, avoid overwatering, and mulch lightly while keeping plant crowns open.
For a classic cottage garden feel, combine Daylilies, Dianthus, Hardy Geraniums, Iris, Lavender, Peonies, Salvia, and Shasta Daisies. This creates a softer, colourful look with a mix of flowers, fragrance, and foliage texture.
Summary
Sun loving perennials are some of the most rewarding plants for Metro Vancouver gardens. They provide strong colour, support pollinators, return year after year, and help build a garden that feels full and lively through much of the growing season.
The best results come from matching each plant to the right location. Some, like Monarda and Veronica, appreciate more consistent moisture. Others, like Lavender, Sedum, Agastache, Yarrow, and Iris, need excellent drainage and should not sit wet in winter. Most of them bloom best with at least six hours of direct sun.
Achillea, Agastache, Coreopsis, Daylilies, Dianthus, Echinacea, Gaillardia, Hardy Geraniums, Iris, Lavender, Monarda, Nepeta, Peonies, Red Hot Poker, Rudbeckia, Russian Sage, Salvia, Shasta Daisy, Upright Sedums, and Veronica all bring something useful to the sunny garden. With thoughtful planting, deep watering during establishment, and simple seasonal maintenance, these perennials can provide years of colour, texture, and garden enjoyment.
