1, lilac is also called lilac, a dense panicle. The origin of "lilacs" was explained by Gao Lian in "Grass Flower Spectrum" in the Ming Dynasty: "Lilacs are small, fragrant and soft, and purple in color." The word "Ding" is actually the word "nail", which is called the original word of "nail" in philology. Lilacs are long and slender like nails, and have a strong fragrance, so they are called "lilacs".
2. Lilac is one of the most common ornamental flowers and trees in China. It is said that it was widely planted in the Song Dynasty. At that time, some people decorated the rockery landscape with lilacs on the mound, which was called "Lilac Zhang". Lilacs must be planted closely. Lilac is one of the flowers listed as twelve friends in Zhang Hui's novel "The Flower in the Mirror".
