Phlomis

Jerusalem Sage

This genus belongs to the Mint family and includes about 100 perennials as well as subshrubs from the Mediterranean and western Asia. Drought-resistant and hardy, many of the species will thrive in warm sunny sites and dry woodland edges. Ornamental whorls of purple, pink or yellow blooms open in the summer, providing long-lasting dry stems and flower clusters for decoration in the garden or kitchen.

<i>Phlomis anatolica</i> ‘Lloyd's Variety’

Brightened by white heavily veined undersides and light fuzzy stems, thick heart-shaped pewter green leaves craft a handsome flanneled appearance. Stiff swarthy stalks thrust upward, interspersed with large long lasting showy whorls of spicy scented helmet-like, rich yellow flowers. This rugged shrubby perennial develops a somewhat woody foundation over time, and always brings fulgent accents to hot exposed slopes, wind-swept seaside plantings or any other sharp-draining sunny locale.

Blooms June–September.

Size: 3' 0" – 4' 0" high x 3' 0" – 4' 0" wide.

Hardy to zone 7.

<i>Phlomis cashmeriana</i>

With a rugged constitution yet stately stature, this enduring Himalayan denizen spawns 12 in. long, spade-shaped gray-green leaves that emphasize a felted aspect, scalloped margins plus luminous silver undersides. Stout woolly stems shoulder the large whorled clusters of tubular lilac-pink blooms above a soft-looking bushy foundation. Adored by birds, bees and butterflies, Phlomis cashmeriana remains evergreen in milder climates, while appreciating proper air circulation, sunshine galore and sharp-draining soil.

Blooms JuneľAugust

Size: 2' 0" – 3' 0" high x 18" – 2' 0" wide.

Hardy to zone 5.

Launched in 1967 by Hilliers, a celebrated British nursery that supposedly received the namesake’s own garden seed, this grand hard-to-find Phlomis is an evergreen hybrid between Phlomis fruticosa and Phlomis russeliana. Commendable even on frosty winter mornings, the 6 to 10 in. tall spires are studded with large clustered snapdragon-like blooms composed of cream-colored hoods plus lemon-yellow lips. Daring spade-shaped green leaves, flashing felted finishes and silver undersides, attire staunch square upright stems beneath a colorful bumble-bee haven. Versatile, vigorous and dependable, deer-resistant ‘Edward Bowles’s can be added to mixed borders or water thrifty plantings.

Blooms June–early October

Size: 4' 0" high x 4' 0" wide.

Hardy to zone 7.

<i>Phlomis fruticosa</i> <i>Phlomis fruticosa</i>

These bright yellow flowers bloom in a series of ball-like clusters known as verticillasters along stout stems and above felted, gray-green foliage. Used as a specimen or blended with Nepeta ‘Walker’s Low’ or Wood Oats, Phlomis fruticosa will provide bold color and form.

Blooms June–August.

Size: 4' 0" high x 3' 0" wide.

Hardy to zone 6.

<i>Phlomis lanata</i>

A golden aura infuses the small gray-green woolly foliage of this soft-looking 2002 AGM winner. Endemic to Crete, long-lived Phlomis lanata sports yellow hooded flowers, rising in whorled widely spaced tiers above a low compact foundation that wards off deer, rabbits and drought. Its stalwart good looks can be intermingled with Mediterranean neighbors such as Rosemary, Rock Roses and Eryngiums.

Blooms June–September

Size: 2' 0" high x 3' 0" wide.

Hardy to zone 7.

<i>Phlomis russeliana</i>

With architectural assertiveness, stout straight stems broadcast separate whorls of butter yellow hooded blooms. Maintaining a stalwart beauty throughout the winter, the stalks look equally impressive whether fresh or dried as they stand above large and broad, heart-shaped olive-green leaves. The fuzzy, scalloped foliage develops into a plush low growing, evergreen cover that keeps those pesky weeds at bay.

In our garden, Phlomis russeliana casts bold accents along a pathway, assorting with Aster ‘Ringdove’ and Molinias.

Blooms June–September.

Size: 3' 0" high x 2' 0" & spreading wide.

Hardy to zone 4.

Phlomis tuberosa (P-0307)

Each $8.00

AVAILABLE LATE AUGUST 2020

<i>Phlomis tuberosa</i>

The small tubers growing from its roots inspired its name and make this Phlomis perhaps the most unusual of all. Fleecy petioles plus large green foliage with toothed margins give the plant a coarse texture that is enhanced by dusty lilac blossoms, nestled in reddish calyxes, and deep crimson-tinged flower stalks. Such distinctive character makes good company for grasses and Lavenders.

Blooms JuneľAugust

Size: 4' 0" high x 3' 0" wide.

Hardy to zone 5.

With green arrow-shaped lush leaves, lustrous burgundy stalks and tiered wreaths of rosy lilac tubular flowers on statuesque stems, this well-mannered perennial adds dignity to the landscape. The toothed downy leaves compose a vigorous bushy base that’s nearly evergreen in many locales and capable of handling drought.

Versatile and equally at home in a formal setting or a meadow planting, ‘Amazone’ can be staged amid Stachys ‘Superba’ and Salvia ‘Amethyst’ for a fantastic purple and pink mélange.

Blooms June – August.

Size: 4' 0" – 5' 0" high x 2' 0" – 3' 0" wide.

Zone 4/5.

Crocosmias boast a bounty of late summer color as our gardens transition into autumn. Displayed on the ends of gracefully arching spikes above winsome sword-like leaves, the clustered tubular flowers range from yellow, peach and orange to fire-engine red. The prismatic tones meld well with white-flowering Hydrangeas and perennials such as Selinium wallichianum, Actaea simplex 'Atropurpurea', Alcea 'Polarstar' or Aster 'Bridal Veil'. The yellow and melon shades sparkle amid the blue blossoms of Aconitum, Caryopteris 'Longwood Blue', Perovskia 'Blue Steel' and  Aster 'Little Carlow'. For sizzling fun you could create a hot border, intermingling them with Kniphofia 'Bee's Sunset', Helenium 'Potter's Wheel' or Helianthemum 'Fire Dragon'. Be sure to add some to your next cut arrangement!

Commonly known as Montbretia, they do their best when provided with good drainage, moderate moisture and some protection from hot afternoon sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

You can trim perennials, such as Nepetas and Geraniums, and savor their fresh new growth plus a flourish of blooms, often until the first frost! We hope some of the plants featured in this newsletter lift your spirits and maybe even inspire a little awe as summer wanes.
