Warren Gardens

Rich saturated crimson-magenta double blooms — one of the deepest notes in the palette. Strong stems, no staking needed, intoxicating fragrance. Foliage deepens to burgundy in autumn.

2.5–3ft × 3ft

Intensely colored English lavender with deep violet-blue spikes and silvery aromatic foliage beautiful even out of bloom. Thrives in sandy coastal soils. Every pass along the path releases its fragrance.

18–24in × 18–24in

Among the darkest flowers in the garden — brooding near-black purple pincushion blooms on long wiry stems that dance in any breeze. Blooms prolifically all summer if deadheaded. The definitive dramatic note in the moody palette.

18–24in × 18in

Enormous tall bearded iris flowers in pure saturated violet-purple — genuinely electric in the late-spring border. The upright sword-like foliage provides architectural structure through the whole season.

3–3.5ft tall

Dramatically large, velvety-soft silver-gray leaves that are essentially flowers in their own right. This low-blooming variety is all about the foliage — the luminous silver ground plane that makes every color beside it sing. The visual mortar of the Blue & Moody border.

12–18in tall × 18–24in wide (foliage)

Cascading clusters of very double white flowers with the faintest blush center — an effect of white lace draped over its support. Profusely blooming with classic old-rose fragrance. Appears in both Front and Terrace palettes, lending continuity across the garden.

Climbing to 8–12ft

Deep glowing crimson masterwort flowers surrounded by a pale starburst collar of bracts — somewhere between a Tudor rose and a jeweled brooch. Brings an elegant, slightly old-world botanical quality to the front border.

18–24in × 18in

RHS Plant of the Centenary — Rozanne blooms continuously from late spring until hard frost, producing violet-blue flowers with a white eye. It sprawls graciously through neighboring plants, weaving six months of color through the whole border.

18in tall × 24–36in wide (sprawling)

An airy cloud of tiny pale lavender-white flowers loved by bees and butterflies. When brushed the foliage releases a refreshing minty fragrance. Front-of-border froth that softens edges and connects larger plants, thriving in sandy coastal soils.

12–18in × 18–24in

Semi-double warm rose-pink flowers that bloom precisely when the summer perennials begin to tire — August through October. They float on tall wiry stems with characteristic nodding grace, carrying the border beautifully into fall.

3–4ft × 2–3ft

Late-season anchor for the front border.

Spring white flower chains AND brilliant orange-scarlet new growth unfurling through spring — two simultaneous displays of extraordinary beauty. A premier broadleaf evergreen, glossy and refined year-round. New growth from red-tinted buds in late winter announces the season.

6–12ft  |  Broadleaf evergreen

A spectacular sculpture in living form — blue-silver twisted needles catch light in constant motion, and the wide spreading hindupan habit creates an immediately mature, ancient-feeling presence. This collector's tree, selected for its particular character, will be the most remarked-upon specimen in the garden.

8.5ft tall × 12ft wide (installed)  |  Slow-growing

Dense green foliage sculpted into distinct rounded cloud-forms — the niwaki style of Japanese garden art. At 11 feet this is a substantial, immediately commanding living sculpture. These trained forms take decades to develop; it will be formal, timeless, and impossible to replicate quickly.

11ft tall (maintained)  |  Year-round interest

Broadly mounding with distinctive fan-shaped pendulous sprays of deep green foliage and golden highlights. Growing wider than tall, these two specimens create substantial weeping cloud forms. Evergreen, structural, and four-season in value.

5–7ft tall × 7–9ft wide

Overlapping shell-like fans of the deepest, richest green arranged in a tiered organic silhouette. A specimen that has taken 20+ years to reach its size, providing an almost meditative presence — serene, unchanging, permanent. Grows very slowly.

8–9ft tall × 5–7ft wide

A naturally dwarf, dense globular falsecypress with particularly fine-textured lace-like foliage. Rounder and more formal than the Nana Gracilis, it provides a compact evergreen presence with its own distinct character — tightly knit and refined.

6ft tall × 4.5–5ft wide  |  Slow-growing

Completely distinct from other Hinoki varieties — 'Filicoides' produces long pendulous fern-like sprays of deep green foliage creating an open, cascading, almost mysterious character. Growing wider than tall, this heavy specimen creates a weeping textural accent unlike anything else in the collection.

6ft tall × 7ft wide

A sculptural tour de force — naturally twisted corkscrew branches with purposeful hindupan pruning create something between tree and living art. Dark needles spiral along gnarled branches in a manner that looks ancient and wind-shaped. Its silhouette against sky or a pale wall is unforgettable.

7–8ft (trained)  |  Slow-growing, maintains character

The garden's scaffolding — upright, densely branching dark green needles forming natural columns. Incredibly tough, shade-tolerant, and salt-resistant. The dark yew is the color that makes every pale flower luminous by contrast.

8–12ft tall × 2–4ft wide  |  Columnar

The English yew in its low spreading form — growing wide and horizontal rather than vertical, creating dark evergreen groundplane structure. At 7–8ft the large specimens will be substantial sweeping presences. Jewel-like red arils in autumn add accent to the dark foliage.

3–4ft tall × 6–10ft wide  |  Low spreading

Luminous white foxglove spires with an unusually silvery-gray cast — almost metallic in certain light. The vertical exclamation marks of the border, rising above everything else. Self-sows freely to maintain a permanent presence.

4–5ft tall in flower

Clouds of tiny daisy-like flowers opening white and aging through pink to rose — the plant carries all three shades simultaneously. Self-seeds into crevices and softens every hard edge. On the terrace it will thread through stone joints in exactly the romantic way that looks accidental but is entirely welcome.

12in tall, spreading to 24in

The defining cultivar of the Blue & Blush choice — warm apricot-blush cupped blooms and strong tea-rose fragrance introducing warmth where the lavenders and salvias are cool and architectural. David Austin English rose of outstanding constitution. The 'blush' in Blue & Blush.

4–5ft × 3–4ft  |  Repeat-flowering

Gossamer haze of lavender-blue from midsummer — silvery-white aromatic stems and finely cut foliage are fragrant when touched, and the effect from a distance is of blue smoke drifting through the border. Drought-tolerant and magnificent in sandy Hampton soils.

2–2.5ft × 2ft  |  Compact form

White lace cascading clusters with faint blush center and classic old-rose fragrance. Used in both Front and Terrace palettes — the white constant that links the whole garden's color story together.

Climbing to 8–12ft

One of the most purely blue flowers in the garden — clean bright cobalt quite unlike the softer lavender-blues of salvia and perovskia. Blooms in late summer when that blue note is most needed. Bees and butterflies are magnetically attracted. Gray-green aromatic foliage is attractive from spring.

2–3ft × 2–3ft

Six months of continuous violet-blue bloom from late spring to hard frost. Sprawls graciously through neighboring plants weaving them together. The thread that unifies the entire terrace planting. (Also used in Front borders.)

18in tall × 24–36in wide  |  Sprawling

A pure airy cloud of tiny white flowers above aromatic foliage from midsummer until frost. Distinguishes the terrace from the front (which uses the pale lavender form) — provides clean white notes bridging the blush tones of Emily Bronte and Crystal Fairy with the blues.

12–18in × 18–24in

Perhaps the most refined white peony — grown since 1856, its large, very double, utterly fragrant white flowers with creamy-yellow center age to pure ivory. Aristocratic restraint: luminous and serene rather than exuberant. Anchors the pale end of the Blue & Blush spectrum.

2.5–3ft × 3ft

Buds inflate like small balloons before opening into wide star-shaped blue flowers — a particularly Japanese refinement in the midsummer border. Clear blue-violet that holds its color well in heat. Clump-forming, long-lived. Note: emerges late in spring — mark its position.

18–24in × 18in

Enormous tall bearded iris in pure saturated violet-purple — genuinely electric in the late-spring border. Upright sword-like foliage provides architectural vertical structure all season. (Also used in Front borders.)

3–3.5ft tall

Masses of small pale blue-lavender five-petaled stars on fine stems — a quiet, filmy edge effect that bridges gaps between larger perennials and softens transitions to paving. The visual equivalent of a rest note in music.

8–12in × 10in  |  Border edge & crevice plant

Cascading fountains of bright golden-green foliage that move in the slightest breeze like a living waterfall — the most graceful ornamental grass for a shaded or partially shaded position. Fall foliage turns orange and russet. Bold in form and delicate in movement simultaneously.

18–24in × 24–30in  |  Spreads slowly

Flat-topped flower plates of soft lilac-mauve that fade gracefully to pale buff as summer progresses, providing months of color from a single flush. Fine ferny foliage is aromatic when brushed. A reliable, long-blooming workhorse that fills the middle of an orchard border with quiet charm. Attracts beneficial insects; tolerates heat and drought once established.

24–30in × 18–24in  |  Drought-tolerant; deadhead for rebloom

The 'Chantilly' series produces open-faced flowers without the traditional closed "snap" lip — wider, more airy, and arguably more beautiful than the classic form. Light salmon carries enough warmth to bridge between the cooler blues and the deeper pinks in the orchard palette. Tall stems (to 30 inches) make them excellent for cutting. A cottage garden classic with a refined modern edit.

24–30in × 10–12in  |  Cool-season; best spring and early summer

The essential blue-purple mass planting of the English-style border: cascading mounds of small silvery-green leaves smothered in lavender-blue flower spikes from early summer, reblooming strongly if cut back after the first flush. Deer-resistant, drought-tolerant, pollinator magnet, and effortlessly beautiful. Perennial of the Year for a reason — Lydia's orchard palette leans on it as its backbone blue.

18–24in × 24–30in  |  Cut back after first flush for rebloom; deer-resistant

White-flowered magenta's cooler sibling — pure white saucers held above felted silver-grey foliage on branched, upright stems. The grey leaf is the key: it ties together all the other palette colors and provides luminosity in the evening garden. A biennial that self-seeds reliably, maintaining its presence without intervention. Its silver-white combination works as a natural neutralizer among stronger orchard colors.

24–36in × 12–18in  |  Self-seeds; silver foliage is the main feature

Large, open lavender-blue cups of exceptional size (to 2 inches across) on tall, slender stems — an heirloom variety that has never been superseded for sheer elegance. The flowers are large enough to read clearly from a distance and refined enough to reward a close look. Excellent for cutting; self-seeds without becoming invasive. Among the most aristocratic of all bellflowers.

30–36in × 12–18in  |  Superb cut flower; deadhead to prevent self-seeding

Tiny daisy flowers that open white and age to rose-pink, creating a perpetual two-tone effect on cascading, fine-stemmed mounds that bloom almost without pause from June to frost. A filler without peer — it softens edges, spills over walls, and threads between larger plants with an effortless, naturalistic quality. A single plant looks accidental; a drift of them looks inevitable.

10–12in × 18–24in (spreading)  |  Blooms June–frost; self-seeds freely

Towering white spires that command the back of the orchard border in high summer — vertical architecture that nothing else in the perennial palette provides. White delphiniums are rarer and more elegant than their blue cousins; they catch evening light and glow at dusk. The 'Guardian' series is more weather-resistant than older hybrids. Staking required, but the effect is worth every effort.

4–5ft × 18in  |  Requires staking; cut back for second flush

A David Austin shrub rose of the highest quality: large, deeply cupped flowers of warm apricot fading to cream, with a powerful myrrh fragrance that announces itself from ten feet away. One of Austin's most reliably repeat-flowering varieties, carrying through from June to the first frost. In the orchard setting, the warm apricot bridges perfectly between the whites and the pinks of the palette.

4–5ft × 4ft  |  Repeat flowering; strong myrrh fragrance

Soft apricot-peach tubular bells spotted within — a warmer, more unusual coloring than the standard white or purple foxglove. Exceptional in a garden that mixes English-style pastel with warm Mediterranean tones. Tall spires command vertical space in early summer before the roses fully open. Self-seeds freely; a colony establishes naturally and perpetuates without replanting.

4–5ft × 18in  |  Biennial/short-lived perennial; self-seeds readily

A low, spreading groundcover rose that covers itself in small clusters of pure white flowers from early summer to frost with almost no maintenance — no deadheading required, excellent disease resistance, and spreading habit that covers ground and suppresses weeds. The ideal edging rose for an orchard garden: it ties the border to the ground plane and provides continuous white through the longest season of any rose in the palette.

18in × 30in (spreading)  |  No deadheading needed; disease-resistant

Elegant tall wands of tiny soft-pink flowers arranged in branching, candelabra-like spires — providing vertical rhythm in mid-to-late summer when many perennials are between flushes. Leaves arranged in neat whorls around the stem make the plant attractive even before flowering. Attractive to bees and butterflies; the dried seedheads persist attractively into winter.

4–5ft × 18–24in  |  Mid-late summer; architectural vertical form

A vigorous climbing rose with fully double flowers of warm apricot-salmon — large, high-centered in the classic exhibition form — carried abundantly on long arching canes. At the café nook rose trellis, 'Polka' will train across the structure and cascade generously, creating the effect of an enclosed floral room. Moderately fragrant; repeat-flowering through summer. Among the most reliably beautiful climbers for an outdoor dining setting.

10–12ft climbing  |  Train on trellis; café nook rose structure

Compact, branched spires carrying saucer-shaped flowers in a blend of biscuit, peach, and rose — the palette is one of the most unusual and painterly in any garden plant. 'Southern Charm' holds its branched, bushy form without the gawkiness of the species. A sophisticated cottage-garden plant that bridges warm and cool tones simultaneously.

24–30in × 18in  |  Short-lived perennial; self-seeds; drought-tolerant

Ruffled medium-blue flowers with a white beard — the archetypal blue bearded iris, providing the clearest blue note in the early-summer orchard garden before the catmint and bellflowers take over. The sword-like grey-green foliage remains attractive after bloom as a structural element. Brief-blooming but memorably beautiful for its moment; pairs naturally with alliums and early roses.

30–36in × 18in  |  Blooms 2–3 weeks in June; foliage structural year-round

Perfect globe-shaped flower heads of deep purple-violet, each composed of dozens of tiny star-shaped florets, held on perfectly straight stems above dying foliage — one of spring's most architectural moments. Plant bulbs through the face of the border for a naturalistic effect; the dying foliage hides behind emerging perennials. The dried spherical seedheads are ornamental well into summer.

24–36in  |  Spring bulb; plant in fall; seedheads persist decoratively

Tall airy columns of tiny lavender-blue flowers on silver-white stems — a haze of color from mid-summer to frost that reads as pure blue from a distance and reveals silver on close inspection. Wildly heat and drought tolerant; actually performs better in lean, dry conditions. The silver stem color is nearly as valuable as the flower. One of the essential late-season plants for any perennial border with a blue-and-silver scheme.

3–5ft × 2–3ft  |  Cut hard in spring; blooms mid-summer to frost
