叶子花是典型的热带花卉,盛开之际,一片鲜艳,一片亮丽,煞是耀眼!在热带和亚热带地区,它是重要的园林绿化植物,又名三角梅、宝中花、九重葛、别名甚多。因其开花繁茂,不是杜鹃,却胜似杜鹃,且茎杆带有锐刺,广东人又习惯称之为“簕杜鹃”,意为“带刺的杜鹃花”。其实,我们所欣赏的艳丽的“花朵”并非真正的“花”,而是由3枚变态叶组成的三角形苞片,“三角梅”、“叶子花”的称呼便因此而来。其真正的花朵很小,隐藏在苞片里,观赏价值不大,也没有苞片艳丽和开放长久。重瓣品种的花器更是完全退化成同色的大大小小的苞片,层层叠叠,密集成团,花后苞片也不易脱落。
Leaf flowers are typical of tropical flowers, blooming occasion, a bright, beautiful, really brilliant! In the tropical and subtropical regions, it is an important landscaping plant, also known as Bougainvillea, Bougainvillea, Bougainvillea many. Because of its lush flowering, not rhododendron, it is better than rhododendron, and stems with sharp thorns, Cantonese has used to call it “Rhododendron”, meaning “prickly rhododendron.” In fact, we enjoy the beautiful “flowers” is not a real “flower”, but by the three metamorphic leaves of the triangular bracts, “Bougainvillea”, “flower leaves” of the salvo will come. The real flowers are small, hidden in the bracts, ornamental value is not, there is no bracts gorgeous and open long. Double flower varieties are completely degenerated into the same color of large and small bracts, layers stacked, dense into clusters, bracts are not easy to fall off after flowering.
