This species features an upright, branched habit, typically reaching \u003cstrong\u003e1 to 3 meters in height\u003c\/strong\u003e. The stems are stiff and become woody with age, covered with slightly cracked bark that gives the plant a mature, natural appearance.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:14pt;\"\u003eMorphological Characteristics\u003c\/h3\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eLeaves appear relatively late in spring, which is a distinctive feature of this species. They are \u003cstrong\u003ethree-lobed, rhomboid or ovate-cuneate\u003c\/strong\u003e, coarsely toothed, measuring 7–9 cm in length. Their gray-green color during the growing season changes to an attractive yellow shade in autumn, extending the plant’s decorative period.\u003c\/p\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eThe true ornament of the Rose of Sharon, however, is its flowers, which develop over a long period from July to September. \u003cstrong\u003eThey are large, bell-shaped, borne singly in leaf axils\u003c\/strong\u003e and can reach an impressive diameter of up to 12 cm. Each flower consists of a corolla formed by five petals surrounding a distinctive pistil and a tube of fused stamens. Depending on the variety, the flowers may be \u003cstrong\u003esingle, semi-double, or double\u003c\/strong\u003e, offering a rich palette of colors from pure white, through various shades of pink and magenta, to blue and purple tones, often with a striking red eye in the center.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:14pt;\"\u003eClimate Tolerance and Growth\u003c\/h3\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eThis species stands out for its \u003cstrong\u003ehigh frost tolerance\u003c\/strong\u003e, considered the most cold-hardy hibiscus in its group. It withstands temperatures down to about -20°C, corresponding to USDA zone 5, making it well suited to the \u003cstrong\u003etemperate climate\u003c\/strong\u003e typical of most European regions. Although not among the fastest-growing shrubs, with proper conditions it can \u003cstrong\u003egrow 30–40 cm per year\u003c\/strong\u003e, gradually reaching its mature size over several growing seasons.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:14pt;\"\u003eCultivation Requirements\u003c\/h3\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003e\u003cstrong style=\"color:#656B39;\"\u003eRose of Sharon\u003c\/strong\u003e prefers \u003cstrong\u003esunny or lightly shaded locations\u003c\/strong\u003e, sheltered from strong winds that can damage the delicate flower petals. The soil should be \u003cstrong\u003efertile, moderately moist, well-drained, with a slightly acidic to neutral pH (6.0–7.5)\u003c\/strong\u003e. Such a substrate ensures optimal root system development and abundant flowering.\u003c\/p\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eCare includes \u003cstrong\u003eregular watering\u003c\/strong\u003e during summer and \u003cstrong\u003efertilizing\u003c\/strong\u003e during active growth and flowering, supporting long-lasting and profuse bloom production. Early spring pruning is recommended to perform \u003cstrong\u003eshaping cuts\u003c\/strong\u003e, which stimulate bush density and result in more spectacular flowering.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:14pt;\"\u003eGarden Uses and Propagation\u003c\/h3\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eIn the garden, Rose of Sharon works well both as a solitary plant and in group compositions. It is also excellent as a \u003cstrong\u003ehedge element or background for flower beds\u003c\/strong\u003e, where its height and dense habit create a natural visual barrier. Due to the wide variety of flower colors and forms available, many ornamental cultivars allow the plant to be adapted to diverse design concepts.\u003c\/p\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eAfter flowering, the plant produces fruit in the form of dry capsules containing seeds. Although sexual propagation is possible, in practical horticulture \u003cstrong\u003esoftwood cuttings in spring or semi-hardwood cuttings in summer\u003c\/strong\u003e are more commonly used, as they root well.\u003c\/p\u003e\n\n\u003cp style=\"font-size:12pt;\"\u003eThe plant may be susceptible to fungal and bacterial diseases such as \u003cstrong\u003egray mold, anthracnose, phytophthora, and dieback\u003c\/strong\u003e. Among pests, the most common are \u003cstrong\u003eaphids, whiteflies, and scale insects\u003c\/strong\u003e. Regular monitoring of the shrub’s health and providing appropriate growing conditions significantly reduce the risk of phytosanitary problems.\u003c\/p\u003e","brand":"mr.seed","offers":[{"title":"5","offer_id":52461556695368,"sku":"1417","price":3.9,"currency_code":"PLN","in_stock":true},{"title":"10","offer_id":52461556728136,"sku":"1418","price":5.9,"currency_code":"PLN","in_stock":true},{"title":"50","offer_id":52461556760904,"sku":"1419","price":17.9,"currency_code":"PLN","in_stock":true},{"title":"100","offer_id":52461556793672,"sku":"1420","price":27.9,"currency_code":"PLN","in_stock":true},{"title":"1000","offer_id":52461556826440,"sku":"1421","price":193.9,"currency_code":"PLN","in_stock":true},{"title":"10000","offer_id":52461556859208,"sku":"1422","price":798.9,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/2649\/0440\/files\/2323.jpg?v=1770321467","url":"https:\/\/www.mrseed.eu\/en\/products\/nasiona-ketmii-syryjskiej-hibiscus-syriacus","provider":"mr.seed","version":"1.0","type":"link"}
