The blooms look softly painted, with rich pink and salmon tones toward the petal edges and a dark red eye in the center. Each flower can reach about 8 inches across, giving the garden the bold, tropical look homeowners love from hibiscus without treating it like a tender annual.\u003c\/p\u003e\n\u003cp\u003eThe flower pattern is what makes Airbrush Effect so memorable. Rather than a flat single color, each bloom has a blended, airbrushed appearance that gives the plant real depth up close and strong color from a distance. Use it where the flowers can be seen and appreciated, such as near patios, sunny walkways, poolside plantings, cottage gardens, rain garden edges, and mixed perennial borders.\u003c\/p\u003e\n\u003ch2\u003eA Compact Hardy Hibiscus With Big Garden Presence\u003c\/h2\u003e\n\u003cp\u003eAirbrush Effect Hardy Hibiscus is compact for a hardy hibiscus, but it still creates a substantial summer focal point. At maturity, expect a broad, rounded plant around 3 to 4 feet tall and 4 to 5 feet wide. The rich green foliage forms a full backdrop for the large pink-and-white flowers, helping the blooms stand out cleanly in sunny beds and large containers.\u003c\/p\u003e\n\u003cp\u003eThis plant is ideal for homeowners who want big hibiscus flowers without choosing a variety that becomes too tall or loose. It works well as a specimen perennial, a back-of-border anchor, a mass planting, or a large container feature. Give it enough room to fill out during summer, because hardy hibiscus grows quickly once warm weather arrives.\u003c\/p\u003e\n\u003ch2\u003eLong-Blooming Summer Color for Pollinators\u003c\/h2\u003e\n\u003cp\u003eAirbrush Effect blooms over a long summer season, producing many buds that open into large, flat flowers. Individual hibiscus blooms may last only a day, but the plant continues producing fresh flowers when it is healthy, well-watered, and growing in strong sun. This makes it valuable for carrying color through the hottest part of the season when many spring perennials are finished.\u003c\/p\u003e\n\u003cp\u003eThe flowers also attract pollinators, including bees, butterflies, and hummingbirds. Plant Airbrush Effect with other summer performers such as coneflowers, black-eyed Susans, bee balm, Joe Pye weed, ornamental grasses, alliums, catmint, and salvia for a sunny pollinator planting with height, texture, and bold color.\u003c\/p\u003e\n\u003ch2\u003eBest in Full Sun, Moist Soil, and Warm Weather\u003c\/h2\u003e\n\u003cp\u003eAirbrush Effect Hardy Hibiscus performs best in full sun with moist, organically rich soil. It can tolerate part sun, but full sun encourages stronger flowering, better stems, and fuller growth. Because hardy hibiscus produces large leaves and massive flowers, consistent moisture is important during active growth and bloom.\u003c\/p\u003e\n\u003cp\u003eThis is a great plant for rain gardens, pond edges, moisture-retentive borders, and low spots that stay evenly moist but still have good airflow. It can adapt to average garden soil when watered well, but it should not be allowed to dry out for long periods during summer heat. Add compost at planting and mulch the root zone to help conserve moisture.\u003c\/p\u003e\n\u003ch2\u003eHardy, Late to Wake Up, and Easy to Maintain\u003c\/h2\u003e\n\u003cp\u003eAirbrush Effect is a hardy perennial hibiscus, not a tropical hibiscus houseplant. It dies back to the ground in winter and returns from the crown in spring. One important buyer expectation is that hardy hibiscus emerges late, often waiting until the soil warms. Mark the planting spot and be patient before assuming the plant did not return.\u003c\/p\u003e\n\u003cp\u003eMaintenance is simple. Cut the old stems back in late winter or early spring before new growth emerges, fertilize as growth begins, and water consistently during hot weather. Deadheading can keep the plant looking clean, but it is not required for the plant to continue blooming. With sun, moisture, and room to grow, Airbrush Effect brings a tropical-looking flower show to a hardy perennial garden.\u003c\/p\u003e","brand":"Walters Gardens","offers":[{"title":"1 Gallon Pot","offer_id":49514182541550,"sku":"pip1788064149904","price":20.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/4347\/1598\/files\/airbrush-effect-hardy-hibiscus_1.png?v=1788064154"},{"product_id":"mercury-rising-coreopsis","title":"Mercury Rising Coreopsis","description":"\u003ch2\u003eA Hardy Red Coreopsis That Breaks Away from Traditional Yellow\u003c\/h2\u003e\n\u003cp\u003eMercury Rising Coreopsis brings an entirely different color palette to the sunny perennial garden. Instead of the golden-yellow flowers associated with most tickseed plants, this distinctive hybrid produces rich wine-red to deep burgundy blooms surrounding small, bright golden centers.\u003c\/p\u003e\n\u003cp\u003eThe velvety flower color creates a warm, saturated display that stands out beautifully against green foliage. It also combines easily with white, pink, lavender, blue, orange, and gold companion plants, giving gardeners more design flexibility than a conventional yellow Coreopsis.\u003c\/p\u003e\n\u003cp\u003eMercury Rising belongs to the Big Bang™ series developed for improved hardiness, longer flowering, vigorous growth, and unusual flower colors. It provides the visual drama of a tender red Coreopsis while offering perennial performance in suitable Zone 5 through Zone 9 gardens.\u003c\/p\u003e\n\u003cp\u003eThis is not an upright, narrow tickseed. The plant remains relatively low while its well-branched stems spread outward, creating a broad flowering mound that can fill the front or middle of a sunny bed.\u003c\/p\u003e\n\u003ch2\u003eVelvety Burgundy Flowers Keep Appearing for Months\u003c\/h2\u003e\n\u003cp\u003eMercury Rising begins flowering in early to midsummer and can continue producing blooms until hard frost. Its sterile or nearly sterile flowers direct relatively little energy into seed production, helping the plant keep developing new buds over an unusually long season.\u003c\/p\u003e\n\u003cp\u003eEach daisy-like flower can reach approximately 1½ to nearly 2 inches across. Deep red ray petals surround a frilly golden-yellow center, producing a crisp contrast that remains visible from across the landscape.\u003c\/p\u003e\n\u003cp\u003eFlower color can change slightly with the weather. Creamy white tips or streaks may appear on the red petals during periods of intense heat or as seasonal conditions change. This is a natural characteristic of the cultivar rather than a sign of damage or incorrect labeling.\u003c\/p\u003e\n\u003cp\u003eIn regions with very hot summers, flowering may slow during the hottest part of the season and resume as temperatures moderate. A light midsummer shear can tidy the plant, encourage fresh growth, and support a renewed fall display.\u003c\/p\u003e\n\u003ch2\u003eA Low, Broad Habit for Borders, Containers, and Mass Plantings\u003c\/h2\u003e\n\u003cp\u003eMercury Rising Coreopsis generally reaches approximately 16 to 18 inches tall while spreading 30 to 36 inches wide. Its low, outward-growing stems create a broad mound that fills considerably more horizontal space than its height might suggest.\u003c\/p\u003e\n\u003cp\u003eUse it near the front of a perennial border, along a sunny walkway or in a broad mass planting where the stems have room to spread. The wine-red flowers make a strong transition between taller purple, pink, and gold perennials.\u003c\/p\u003e\n\u003cp\u003eMercury Rising also performs well in patio containers with dependable drainage. Its wide habit can soften the edge of a large planter, while the continuous red flowers provide months of color near decks, entrances, and outdoor seating areas.\u003c\/p\u003e\n\u003cp\u003eGive each plant enough room to develop. Crowding can reduce airflow and make the naturally spreading stems look tangled. In rich or frequently irrigated soil, the plant may open in the center or sprawl more than it would in average, leaner soil.\u003c\/p\u003e\n\u003ch2\u003ePollinator-Friendly Flowers Without Unwanted Heavy Seeding\u003c\/h2\u003e\n\u003cp\u003eThe open, daisy-like blooms are easy for bees, butterflies, and other beneficial insects to visit. Their long flowering season helps provide a dependable source of nectar and pollen from summer into fall.\u003c\/p\u003e\n\u003cp\u003eMercury Rising produces little to no viable seed under normal conditions. That means it is less likely to scatter large numbers of volunteer seedlings through the garden than fertile Coreopsis cultivars.\u003c\/p\u003e\n\u003cp\u003eLow seed production also reduces the need for constant deadheading. Gardeners can still remove faded flowers for a cleaner appearance, but the plant continues blooming because it does not quickly shift all its energy into developing seeds.\u003c\/p\u003e\n\u003cp\u003eMercury Rising is a hybrid derived from North American Coreopsis breeding lines rather than a straight native species. It works well in pollinator-friendly and native-inspired landscapes, but it should be considered a native-rooted hybrid rather than a local ecotype or a straight species wildflower.\u003c\/p\u003e\n\u003ch2\u003eFull Sun and Sharp Drainage Are the Keys to Long-Term Success\u003c\/h2\u003e\n\u003cp\u003ePlant Mercury Rising Coreopsis in full sun for its densest habit, strongest stems, and heaviest flower production. It can tolerate light partial sun, but too much shade may reduce flowering and increase the plant’s tendency to spread open.\u003c\/p\u003e\n\u003cp\u003eAverage to lean, well-drained soil is ideal. The plant tolerates sandy soil, dry soil, and occasional drought after establishment, but it does not perform well where winter moisture remains around the crown.\u003c\/p\u003e\n\u003cp\u003eWater regularly during the first growing season, then allow the upper soil to dry slightly between waterings. Avoid heavy fertilizer, excessive compost, and frequent irrigation, all of which can encourage soft, sprawling growth.\u003c\/p\u003e\n\u003cp\u003eMercury Rising was bred for strong resistance to powdery mildew and leaf spot, although regional performance can vary in humid climates. Full sun, generous spacing, and soil-level watering remain important. In the Mid-Atlantic, excellent winter drainage is especially valuable because wet soil can reduce longevity even where winter temperatures fall within the stated hardiness range.\u003c\/p\u003e","brand":"Garden Goods Direct","offers":[{"title":"1 Gallon Pot","offer_id":49514182639854,"sku":"msj1788064155196","price":22.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/4347\/1598\/files\/mercury-rising-coreopsis_1.jpg?v=1788064159"},{"product_id":"orange-marble-heliopsis","title":"Orange Marble Heliopsis","description":"\u003ch2\u003eColorful Marbled Leaves Start the Display Before Summer\u003c\/h2\u003e\n\u003cp\u003eOrange Marble Heliopsis offers something most false sunflowers cannot: ornamental foliage that deserves attention before the first flower opens. Its green leaves are irregularly marbled with creamy yellow, pale gold, and red-purple tones, creating a lively pattern that changes from one leaf to the next.\u003c\/p\u003e\n\u003cp\u003eYoung foliage may carry stronger reddish or pink-purple markings along the margins and veins. As the leaves mature, the pattern develops into a varied mixture of green, yellow, and burgundy-red accents rather than a simple two-color edge.\u003c\/p\u003e\n\u003cp\u003eThis marbling makes Orange Marble useful even before its midsummer bloom period begins. The foliage brightens sunny borders, adds contrast beside solid-green plants, and provides a transition between silver, burgundy, gold, and orange companion plants.\u003c\/p\u003e\n\u003cp\u003eBecause the variegation is naturally irregular, individual leaves and stems will not look identical. That variation is part of the cultivar’s ornamental character and gives the plant a more layered appearance than a uniformly striped or edged perennial.\u003c\/p\u003e\n\u003ch2\u003eChocolate-Colored Buds Open into Warm Orange Flowers\u003c\/h2\u003e\n\u003cp\u003eDark chocolate-brown flower buds rise above the foliage, providing a strong contrast before opening. The buds gradually reveal warm orange, daisy-like flowers with brighter yellow-orange coloring toward the tips of the petals.\u003c\/p\u003e\n\u003cp\u003eEach flower reaches approximately 2 to 2½ inches across. The rounded petals surround a deeper orange-brown center, creating a rich summer display that coordinates with both hot-color gardens and softer naturalistic plantings.\u003c\/p\u003e\n\u003cp\u003eOrange Marble generally begins flowering in July and can continue into late September. Removing faded flowers helps maintain a clean appearance and encourages the plant to continue developing buds rather than directing all its energy into seed.\u003c\/p\u003e\n\u003cp\u003eThe flowers are not fragrant, but their unusual coloring and dark buds give the plant plenty of visual interest. The long stems may also be cut for warm-colored summer arrangements with purple coneflowers, blue salvia, garden phlox, and ornamental grasses.\u003c\/p\u003e\n\u003ch2\u003eA Compact Rounded Habit for Borders and Patio Containers\u003c\/h2\u003e\n\u003cp\u003eOrange Marble Heliopsis generally grows approximately 24 to 32 inches tall and 18 to 24 inches wide. It develops a compact, freely branching, and rounded habit that is easier to place than traditional false sunflowers, reaching four feet or more.\u003c\/p\u003e\n\u003cp\u003eIts medium height works well through the front or middle of a sunny perennial border. The plant is tall enough to rise above low groundcovers but compact enough to avoid hiding coneflowers, salvias, and other medium-sized companions.\u003c\/p\u003e\n\u003cp\u003eUse Orange Marble as a single colorful accent or repeat several plants through a broad bed. Its patterned foliage creates continuity before flowering, while the orange blooms provide a stronger seasonal display during midsummer and late summer.\u003c\/p\u003e\n\u003cp\u003eOrange Marble can also grow in a large patio container with dependable drainage. Its combination of foliage and flowers makes it especially useful in containers, as the plant remains ornamental beyond its main bloom period.\u003c\/p\u003e\n\u003ch2\u003eLong-Season Flowers Welcome Bees and Butterflies\u003c\/h2\u003e\n\u003cp\u003eOrange Marble’s warm orange flower heads attract bees, butterflies, and other beneficial pollinating insects. The open, daisy-like blooms provide convenient landing areas and accessible pollen during the height of summer.\u003c\/p\u003e\n\u003cp\u003eIts flowering period continues into early fall, helping to extend the season of color and pollinator activity after many spring and early-summer perennials have finished blooming.\u003c\/p\u003e\n\u003cp\u003ePlant Orange Marble with coneflowers, agastache, perennial salvia, asters, and native ornamental grasses to create a longer sequence of nectar and pollen. Purple and blue companions provide an especially effective contrast with the orange flowers and cream-yellow foliage markings.\u003c\/p\u003e\n\u003cp\u003eOrange Marble is a cultivar of a North American native species, but it originated as a selected nursery seedling in Europe. It is best described as a cultivar of a native species rather than a straight native wildflower or local ecotype.\u003c\/p\u003e\n\u003ch2\u003eFull Sun and Well-Drained Soil Maintain the Best Color\u003c\/h2\u003e\n\u003cp\u003ePlant Orange Marble Heliopsis in full sun for its densest habit, strongest stems, and heaviest flowering. Good sunlight also helps develop the strongest contrast among the green, yellow, and red-purple foliage tones.\u003c\/p\u003e\n\u003cp\u003eChoose average, well-drained soil. Orange Marble tolerates occasional drought after establishment, but regular deep watering during extended summer dryness will help maintain its foliage and flower production.\u003c\/p\u003e\n\u003cp\u003eAvoid heavy fertilizer and constantly saturated soil. Rich, overly wet conditions can encourage soft growth and reduce the compact habit. A light spring application of compost is usually sufficient in average garden soil.\u003c\/p\u003e\n\u003cp\u003eOrange Marble has been introduced for strong performance in heat, drought, and humidity.
