Love to draw Cats with Flowers, and also one with the Hydrangea Flowers. Hope you enjoy it. HYDRANGEA BRIEF INFORMATION Common names: hydrangea, hortensia. Hydrangea (scientific name: Hydrangea) is a genus of about 100 species of flowering plants native to southern and eastern Asia (from Japan to China, the Himalaya and Indonesia) and North and South America. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. Four-petaled flowers grow in round clusters that are usually 4 to 8 inches wide. Flowers bloom in white, lavender and pink. While the hydrangea has been a favorite in the garden or landscape for years, it has become a popular cut flower to enhance garden-style flower arrangements.
