HARLEQUIN’S GARDENS’ 20th ANNIVERSARY SALE
Save 20% off Selected Plants, Soil Amendments & Products
on the 20th of every month this season
20/20 Sale for FRIDAY JULY 20th
This month we are featuring a sampling of the hundreds of great Xeriscape plants for which Harlequin’s Gardens is well known, and a few of our excellent soil products. And we always include some ‘Surprise’ additions to the sale!
Ceratostigma plumbaginoides (Hardy Blue Plumbago, Leadwort)
An outstanding, extremely adaptable and long-lived deciduous groundcover to 6-12” tall and 18” wide, Plumbago will grow equally well in shade or sun, and is not fussy about soils. It is tolerant of quite low-water conditions, especially in shade. The foliage is slow to emerge in spring, so small, early-spring bulbs like species crocus and ‘botanical’ iris can be planted in its midst. The beautiful ¾” vivid cobalt blue flowers begin blooming in mid to late summer, and continue into autumn, when the foliage turns deep red – a memorable combination! Plumbago spreads underground, and can overtake other plantings, so choose your location wisely. It looks great sprouting between rocks (if planted near a dry-laid stone wall it will find its way there). Hardy to Zone 5 / 7,000’.
Euonymus fortunei ‘Coloratus’ (Purleleaf Wintercreeper) in 1-gallon pots
Purpleleaf Wintercreeper is a tough broad-leafed evergreen that can be grown in shade or sun as a groundcover (12-18” tall and spreading), as a sheared shrub or hedge 24” tall and 36” wide, or as a vine to 8’ tall. How’s that for versatility! Once established, this Euonymus is very drought-tolerant. The pointed oval leaves are leathery and semi-glossy, and turn purple in winter (hence the common name). It requires some management to guide it into the form you desire, but just think: as a vine, Purpleleaf Wintercreeper can completely obscure a chain link fence, year-round! Cold-hardy to 7,000’.
Euonymus fortunei ‘Minima’ in 1-gallon pots
This selection of E. fortunei is a tough broad-leafed evergreen vine that does best in shade, morning sun, or year-round dappled shade. Its smaller, semi-glossy dark green leaves make it a more elegant and refined-looking vine than its larger-scale relatives. It will easily grow to 10’ tall on a trellis, fence or wall. ‘Minima’ is drought-tolerant once established and cold-hardy to Zone 4.
Humulus lupulus ‘Aureus’ (Golden Hop Vine)
in 1-gallon pots
A vibrant and highly ornamental selection of Hops, ‘Aureus’ is a very fast-growing, twining perennial to 15’ with deeply lobed, maple-like leaves in a luminous, glowing shade of citron yellow. Golden Hops provides very fast screening or shade on a trellis or arbor (or even on strings), or coverage on a blank wall or fence or telephone pole. It grows in leaps and bounds in May – 6” a day! Golden Hops can also be allowed to weave through the garden and over spring-flowering shrubs, providing a bright yellow-green connecting ‘theme’ (but this requires diligent removal wherever it may have rooted along the way). All hops do sucker, but the suckers are not too difficult to dig out as long as they don’t tangle with perennials. Since it is an herbaceous perennial, Golden Hop vine dies back to the ground in winter, but re-sprouts in spring, bigger and stronger every year. It will grow in sun or shade (best color in sun), in most soils, with very little water once established. As with other hop vines, the inflorescences or ‘cones’ of Golden Hops can be used for tea or ‘dream pillows’ to help with sleep, for making beer, etc. Wear gloves and long sleeves when taking down the dead stalks at the end of the season. Hardy to Zone 4.
LAVENDER: All Lavenders originated in Southern Europe. While lavenders appreciate some supplemental watering in hot weather, they are very drought-tolerant. Good drainage is key to their success, and is especially important for their winter survival. Plant them in a sunny spot, and avoid overly rich soil. Lavender is at home in our alkaline soils, and would rather be grown in lean soil without supplemental nitrogen. All Lavender varieties are evergreen, and have highly aromatic foliage and flowers which attract butterflies and bees and aren’t bothered by deer or rabbits. Lavender should be sheared in early spring and again in summer, right after it has finished blooming. Though cold-hardy in most of our region, after some years, Lavender may become too woody and need replacement. Lavandin (French hybrid Lavender) is typically replaced after 3 to 5 years. In our region, it is best to plant Lavender before autumn. Try it in combination with ornamental grasses, any of the summer-blooming Hyssop (Agastache) selections like ‘Coronado’ (orange) and ‘Sonoran Sunset’ (pink), Filigree Daisy (Anthemis marschalliana), ‘Amethyst Falls’ Ornamental Oregano, ‘Silver Blade’ Evening Primrose, Sulphur Flower and Wine Cups (Callirhoe involucrata). But lavender looks great with practically everything, and is at home in both formal and informal designs.
Lavandula angustifolia ‘Hidcote’ (Hidcote English Lavender)
This choice, compact plant to 24” tall (with bloom spikes) and 18-24” wide, is highly successful and popular. The gray-green foliage sets off the spikes of fragrant deep blue-violet flowers. Cold-hardy to Zone 5.
Lavandula angustifolia ‘Krajova’ (Czech or Country Lavender)
Country Lavender hails from northern Europe and in early summer produces profuse beautiful large, deep purple-blue flowers with exceptionally high essential oil content, and a unique, softly invigorating scent. A favorite lavender for tea and oil infusions. Very cold-tolerant and long-lived. Stout mounded plants are larger than most ‘English’ lavender selections, with flower stalks up to 36-48” tall. Cold-hardy to zone 4/5.
Lavandula angustifolia ‘Munstead’ (Munstead English Lavender)
Sometimes called Dwarf Munstead, this very popular and dependable strain is named after Munstead Wood, the home of the famous garden designer Gertude Jekyll. Munstead produces abundant spikes of sweetly fragrant blue-lavender flowers, above compact mounds of narrow grey-green foliage. Grows to 18” tall (with flower spikes) and 12-18” wide. An excellent choice for edging paths, and for herbal and culinary use. Said to be somewhat more heat-tolerant than other varieties, and one of the most cold-hardy. If promptly dead-headed after its early summer bloom, Munstead will often bloom again in late summer. Cold-hardy to zone 5 (4?).
Lavandula angustifolia ‘Potpourri White’ (‘Ellegance’ White English Lavender)
An elegant, compact companion to or substitute for purple English Lavenders, this one is just as fragrant, deer/rabbit resistant, drought-tolerant and attractive to bees and butterflies, and is cold-hardy to -20 degrees F. Potpourri White bears an abundance of dense spikes of large white flowers from July to September, and makes a compact mound to 12-14” tall and 10-12” wide, with rich green foliage, thriving best in full sun and moderately fertile, well-drained soil. Also nice in containers!
Lavandula angustifolia vera (Old Fashioned/True English Lavender)
Native to Southern Europe, this is the original wild species of what has come to be called ‘English’ lavender (‘Vera’ means ‘true’). An outstanding performer, ‘Vera’ blooms in early summer and has superior cold-hardiness. The sweet, highly fragrant lavender flowers on thin spikes are excellent for medicinal, aromatic and culinary uses, and as cut-flowers. The dense, bushy plants grow to 18”-24” tall and 24-30” wide. Our plants are grown from wild-harvested seeds from an unchanged landrace. Cold-hardy to Zone 4b.
Lavandula x intermedia ‘Grosso’ (Fat-Bud Lavandin)
The name Lavandin refers to the French hybrid varieties commonly grown in France for use in making perfumes and sachets. Grosso’s exceptional abundance of very long spikes of fragrant, deep violet flowers standing well above the grey-green foliage in mid-summer make it perfect for weaving Lavender ‘wands’, for cut-flowers, etc.. The flowers have a strong lavender fragrance with a hint of camphor. Grosso is larger in all respects than any of the English (angustifolia) selections – a larger plant (30” tall and 24-30” wide), with longer, wider leaves and longer flower spikes. Grosso is less cold-hardy than English Lavender, to Zone 5-6, but is the hardiest of the French Hybrid Lavenders and has proven quite successful in the Boulder-Denver area.
Juniperus scopulorum (Rocky Mountain Juniper) in 2-gallon pots
One of the emblematic trees of the Interior West, Rocky Mt. Juniper is a locally native evergreen tree offering perfect acceptance of our drought, wind, alkaline soil and erratic weather patterns, requiring almost no care. A very drought-tolerant tree, it will grow at a slow to moderate rate to 20-25’ tall and 8-12’ wide, in an upright and pyramidal shape. The dense foliage has a gray or blue-gray cast, and the bark and blue berries are very attractive. Rocky Mt. Juniper is great for screening and windbreaks, and takes up less horizontal space than most conifers. It provides great shelter for small birds. Cold-hardy to 10,000’.
Penstemon pseudospectabilis (Desert Beardtongue)
This showy, long-blooming Penstemon is native to southern New Mexico but is surprisingly cold-hardy and easy to grow here in the dry garden. The long spikes of hot-pink flowers, up to 36” tall, are beautifully set off by large blue-gray leaves. If you keep spent flowers removed and give it a few deep soakings in the heat of the summer, it will bloom for many months. Very happy in a hot, sunny spot in well-drained soil. Desert Beardtongue is popular with hummingbirds, and looks terrific with Western Spiderwort, California Poppy, and silver or blue-grey-foliaged plants like ‘Powis Castle’ or ‘Seafoam’ Artemisia, and Moon Carrot. Resists rabbits and deer. Cold-hardy to Zone 5.
Penstemon strictus (Rocky Mountain Penstemon)
One of the showiest, easiest to grow, longest-lived Penstemons for our region. From the glossy evergreen foliage, the 1-2’ tall flowering stalks rise straight up, clothed in large, intense deep blue-violet flowers, blooming for more than a month in late spring. Rocky Mt. Penstemon grows best in well-drained soils and tolerates both drought and moister conditions. It self-sows readily, and also spreads by stolons to form large clumps. Resists rabbits and deer. Try growing it with ‘Kannah Creek’ Sulphur Flower, Jupiter’s Beard (Centranthus ruber), Filigree Daisy (Anthemis marschalliana), ‘Moonshine’ Yarrow, Oriental Poppy ‘Beauty of Livermere’ or ‘Princess Victoria Louise’. Cold-hardy to Zone 3.
Sedum spurium ‘Red Carpet’ (Red Carpet Stonecrop)
One of the best evergreen groundcovers for low-water gardens, ‘Red Carpet’ has strongly red-tinted, succulent, wedge-shaped leaves on trailing stems and forms a dense, weed-smothering, flowering carpet topped by clusters of starry carmine flowers in midsummer. Butterflies and bees love the flowers. The red foliage color intensifies to rich mahogany-crimson in fall and winter, and is not prone to reversion to green. ‘Red Carpet’ stays low, to 2-4” high, and spreads 12-18”. Plant in full sun or light shade in average to lean well-drained soil, and don’t over-water. Once established, hot dry conditions and poor stony soils are not a problem. Cold-hardy to Zone 3/ 8,500’.
Sporobolus wrightii (Giant/Wright’s Sacaton grass) in 1 gallon pots
The largest of the native grasses in our region, Wright’s Sacaton’s extravagant fountain of foliage 3-5’ tall and airy flower/seed plumes to 6-7’ tall make a great focal point in Xeriscape garden. This Southwest native is long-lived, adaptable and drought-tolerant, and will grow in most soils, in full sun or part shade, and can be grown with very low water once established. Wright’s Sacaton is a ‘warm-season’ grass, which means it is actively growing in late spring and summer, and blooms late in the season. The attractive dry, wheat-colored foliage can be left standing through the winter and cut down in early spring. Use as an accent, among tall, late-blooming perennials such as Pitcher Sage (Salvia azurea/ S. pitcheri), Anise Hyssop (Agastache foeniculum), Willow-leaf Sunflower (Helianthus salicifolius), Tall Globe Mallow (Sphaeralcea sp.) and shrubs like Rabbitbrush, Sumac, Fernbush and Bluemist Spirea, or as a seasonal ‘shrub’, a seasonal ‘living fence’ or windbreak. Cold-hardy to Zone 5, 7000’.
Tradescantia occidentalis (Western Spiderwort)
One of the most graceful and beautiful native wildflowers of our short-grass prairie and dry foothills. The lovely three-petaled blue-purple flowers are held in clusters emerging from boat-shaped bracts, and appear in succession in June and July atop 12” to 24” high grass-like foliage. Multiple flower-stems can be blooming on one pant simultaneously, making a striking display, as I witnessed this spring in Left Hand Canyon. Western Spiderwort is a very hardy member of a mostly tropical and subtropical family (including the houseplants known as ‘Wandering Jew’ and ‘Bridal Veil’). It is very drought-tolerant, highly deer-resistant, re-seeds a little but is not at all invasive, and supports native bee species. Spiderwort goes dormant in mid-late summer. Thrives in sun or part-shade in any well-drained soil; a low-care gem for the xeriscape border or meadow. Grow with Blanket Flower (Gaillardia aristata), Mexican Hat (Ratibida columnifera), and Fendler’s or Prairie Sundrops (Calylophus hartwegii and C. serrulatus). Cold-hardy to Zone 3.
Vinca major (Big-Leaf Periwinkle)
Where all else fails, Vinca major will probably grow! A very handsome, weed-smothering, trailing evergreen groundcover 6 to 12” tall and spreading to at least 18-24”, with dark green, glossy oval foliage, and pretty 1” blue flowers in spring. Big-leaf Periwinkle thrives in sun or shade. Once established, it can survive on minimal water and care, the trailing stems rooting where they rest on the soil. This is not a plant for the refined garden, as it does not play well with others, but is really serviceable and attractive for covering some territory in places where neglect is the only care available. Cold-hardy to 8,000’.
