Throughout the seasons, this captivating perennial displays spectacular summer interest—in mid to late summer (July-September), the plant produces its most spectacular display. The flowers are tubular with five spreading petal lobes creating classic phlox form, measuring 2-2.5cm across and arranged in large dense dome-shaped to pyramidal flower heads (panicles) measuring 10-15cm across at stem tips creating substantial displays. The flower colour is the cultivar’s most spectacular feature—each flower is white with striking pink to rose-pink stripes radiating from the centre creating enchanting candy-striped effect. The striping pattern varies slightly from flower to flower—some flowers show bold distinct stripes, others show softer blush-pink striping or pink-edged petals, creating charming variation within each flower head. The overall effect is delightfully cheerful and cottage garden charm—like old-fashioned peppermint candy! The flowers are sweetly fragrant, particularly in evenings, with honey-like scent attracting butterflies, bees, hoverflies, and other beneficial pollinators. The flowering is profuse—multiple flower heads are produced on upright stems creating abundant displays. Flowering lasts 6-8 weeks, and deadheading spent flower heads encourages continuous blooming and may extend flowering into early autumn. The flowers are excellent for cutting, lasting well in fresh arrangements and bringing fragrance indoors. The foliage provides attractive backdrop—the leaves are lance-shaped to elliptical, measuring 8-12cm long with smooth edges and pointed tips, arranged in opposite pairs along upright stems. The foliage is mid-green to dark green creating lush presence. The foliage emerges in spring, supports summer flowering, and dies back to ground level in autumn/winter—this is a herbaceous perennial with no above-ground presence in winter. The growth habit is upright and clump-forming—multiple stems arise from basal crown creating bushy presence. Mature plants typically reach 60-90cm tall and 45-60cm wide. Growth is moderate to vigorous, forming substantial clumps within 2-3 years. The overall effect is charming, colourful, and delightfully fragrant—like having candy-striped summer blooms with sweet fragrance creating cheerful displays with cottage garden appeal and excellent pollinator value.

Native to eastern North America where Phlox paniculata (garden phlox or summer phlox) grows wild in moist woodlands, meadows, and stream banks, this species has been cultivated in gardens for centuries and was a favourite in Victorian cottage gardens. The genus name Phlox comes from the Greek word for “flame,” referring to the brilliant flower colours of some species. The species name ‘paniculata’ refers to the panicle-shaped flower heads. ‘Candy Stripe’ is a modern cultivar specifically selected for exceptional white flowers with striking pink to rose-pink stripes creating unique candy-striped effect (one of the most charming bicolour phlox), long flowering season providing weeks of summer colour, sweet fragrance attracting pollinators, and excellent garden performance. This represents one of the finest striped phlox—the candy-striped pattern is particularly distinctive and cheerful. Hardy to RHS H7, this robust perennial thrives throughout UK and Ireland with complete reliability, tolerating cold winters (to -25°C) and returning vigorously each spring. Moderate to vigorous growth rate, forming substantial clumps within 2-3 years. Particularly valuable for enchanting white flowers with striking pink stripes creating unique candy-striped effect, long flowering season July to September providing weeks of summer colour, sweet fragrance attracting butterflies and bees, excellent cut flowers for fresh arrangements, and cottage garden charm. The combination of charming striped flowers, long blooming season, and sweet fragrance makes this outstanding for summer borders and cottage gardens.

Create stunning compositions by planting in mixed borders where the candy-striped flowers create charming focal points and the upright habit provides vertical interest, using in cottage gardens where the old-fashioned charm and fragrance create authentic period atmosphere, or positioning in cutting gardens where the long-stemmed fragrant blooms provide excellent material for fresh arrangements. Exceptional in pollinator gardens where the fragrant flowers attract butterflies, bees, and beneficial insects, in fragrance gardens positioned near seating areas or pathways where the sweet evening scent can be appreciated, or in containers on patios creating portable summer displays. Works beautifully combined with complementary summer perennials—purple salvias and nepetas for complementary contrast, yellow rudbeckias and coreopsis for warm vibrant combinations, or white shasta daisies and white echinacea for sophisticated monochrome schemes. Also magnificent combined with ornamental grasses (Calamagrostis, Panicum, Pennisetum) for textural contrast and movement, roses (particularly pink or white varieties) for romantic cottage garden combinations, or other cottage garden favourites (delphiniums, lupins, campanulas, geraniums) for traditional layered plantings. Perfect for adding charming striped summer colour, sweet fragrance, and cottage garden appeal to mixed borders, cottage gardens, cutting gardens, pollinator gardens, and summer displays. Excellent for attracting butterflies and bees!

Planting: Space plants 45-60cm apart for individual specimens—they will fill out to form substantial clumps. Plant container-grown specimens in spring (March-May) or autumn (September-November) for best establishment. Choose position in full sun to partial shade—full sun produces most profuse flowering and strongest stems, while partial shade (particularly afternoon shade) is tolerated and can help prevent mildew in hot dry conditions. Prefers sheltered positions protected from strong winds which can damage tall flowering stems. Dig generous planting hole twice width of root ball and same depth. Requires moist, well-drained, fertile soil for best performance. Incorporate generous amounts of organic matter (well-rotted compost, leaf mould, well-rotted manure) into planting hole and surrounding soil to improve moisture retention and fertility—phlox are hungry feeders and appreciate rich soil. Plant at same depth as in container, ensuring crown is level with surrounding soil. Backfill carefully, firming gently. Water thoroughly after planting. Apply 5-8cm mulch around base, keeping mulch clear of crown (5cm gap). Water regularly during first growing season and during dry spells—phlox appreciate consistent moisture. Position where the candy-striped flowers and sweet fragrance can be appreciated, particularly near seating areas or pathways.

Soil Preparation: Prefers moist, well-drained, fertile soil for best growth and flowering. Tolerates wide pH range from slightly acidic to neutral (pH 6.0-7.5). Thrives in rich loamy soils with good moisture retention. IMPORTANT: Requires consistent moisture, particularly during flowering—avoid dry soils which stress plants and reduce flowering. Also requires good drainage—avoid waterlogged conditions which cause root rot. Improve ordinary soils by incorporating generous amounts of organic matter (well-rotted compost, leaf mould, well-rotted manure) to improve both moisture retention and fertility. Phlox are hungry feeders and benefit from rich fertile soil. Mulch annually in spring with 5-8cm layer of organic matter around base to conserve moisture, suppress weeds, improve soil fertility, and keep roots cool. Keep mulch clear of crown. Best flowering occurs in full sun with moist, well-drained, fertile soil—these conditions produce the most profuse blooms and strongest stems.

Container Growing: Can be grown in containers, though best performance is typically in-ground where roots can access consistent moisture. Use large container (minimum 30-40cm diameter), soil-based compost (John Innes No. 2 or No. 3) enriched with extra compost, and ensure excellent drainage. Position in full sun to partial shade. Water regularly—never allow compost to dry out completely, particularly during flowering. Phlox in containers require more frequent watering than in-ground plants. Feed every 2-3 weeks during growing season (April-September) with balanced liquid fertiliser. Deadhead spent flower heads to encourage continuous blooming. Top-dress annually in spring with fresh compost. Divide and repot every 2-3 years in spring to maintain vigour. Container specimens may not grow as tall or flower as profusely as in-ground plants.

Seasonal Care: Low to moderate maintenance! Deadhead spent flower heads regularly throughout flowering season to encourage continuous blooming and may extend flowering into early autumn—cut back to next set of leaves or buds. After flowering finishes and foliage begins to die back in autumn (October-November), cut all stems to ground level. Apply general-purpose balanced fertiliser or blood, fish and bone in spring (March-April) to promote healthy growth and profuse flowering—phlox are hungry feeders and benefit from annual feeding. Mulch annually in spring with organic matter. Water regularly during dry spells, particularly during flowering—consistent moisture is essential for best performance. IMPORTANT: Watch for powdery mildew on foliage in hot dry conditions or crowded plantings—prevent by ensuring good air circulation (avoid overcrowding), watering at base rather than overhead, mulching to maintain soil moisture, and choosing sunny positions. If mildew occurs, remove affected leaves and improve air circulation. Thin stems in spring (when shoots are 15-20cm tall) by removing one-third of stems to improve air circulation and reduce mildew risk—this also produces stronger stems with larger flower heads. Generally pest-free. Watch for slugs and snails on emerging shoots in spring (protect if necessary). The candy-striped flowers are reliably charming!

Division: Divide clumps every 3-4 years in spring (March-April) or autumn (September-October) to maintain vigour, prevent overcrowding, and propagate. Lift entire clump carefully with garden fork, shake off excess soil, and divide into sections ensuring each section has healthy roots and several shoots. Discard old woody central portions, keeping younger vigorous outer sections. Replant divisions immediately at same depth in improved soil, water thoroughly, and mulch. Division rejuvenates plants and maintains flowering performance!
