This deciduous shrub, native to East Asia (China, Japan, Korea), is valued for its large white flowers with a deep red center and its long blooming period from summer to autumn. 'Red Heart' is a popular choice for gardens due to its striking floral contrast and hardiness, making it ideal for borders, hedges, or as a solitary plant.\u003c\/p\u003e\n\u003ch4 dir=\"auto\"\u003eAppearance of leaves, flowers, and fruits\u003c\/h4\u003e\n\u003cul dir=\"auto\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaves\u003c\/strong\u003e: The leaves are deciduous, \u003cstrong\u003edark green\u003c\/strong\u003e, ovate or three-lobed, with toothed edges, measuring 5-10 cm long.
