Dianthus, Dianthus is a perennial herbaceous flower. Also known as Luoyang Flower, it is produced from north to central China. The whole plant is pink and green, with opposite leaves. The stem foot is one foot high, slender and green. It blooms in late spring and early summer and lasts until autumn. Its flowers are beautiful, including red, pink and white. This kind of flower is sparsely born at the end of pink-green branches, and the tips of petals are shallowly split into uniform serrations. It is unique. In Li Bai's poems, there is a poem "Dianthus embroidered Luo Yi", and in Du Fu's poems, there is a poem "Musk sleeps Dianthus", praising its various fragrances. Hundred schools of thought chanted or compared dusk, or wild butterflies fought for white, and the court reflected red, praising them for their fresh and elegant state after the spring dew and autumn wind, praising them for smearing pink in the valley of Shan Ye and savoring them carefully. As the poet said, "Beauty is spring breeze."
