菊花

①俗云："赏菊之趣在于赏花。"菊花的颜色五彩缤纷，以黄、红、白、紫为主。黄的如"黄昏弄月"，金光灿烂，华贵雍容；红的像"金背大红"，绚丽夺目，热情奔放；白的有"白西施"，淡妆素裹，清洁怡雅；紫的是"紫玉莲"，苍劲有力，凝重浑厚。还有一种叫"绿牡丹"的，花呈绿色，青翠欲滴，恰似碧玉，煞是名贵。另有"墨荷"的黑紫堪称花中一绝；更有那"碧玉勾盆"，粉碧兼备，娇而不艳；"凤凰振羽"，红黄相间，娇娆多姿。各种颜色，应有尽有，令人眼花缭乱，目不暇接。

②菊花的花形也是千姿百态，风貌迥异。这是由于花瓣的千姿百态所致。瓣分挂瓣、匙瓣、平瓣、管瓣四种。每一种又有内曲、反卷、龙爪、毛刺等形态。各种花瓣以一定规律进行组合，形成一种保持机体均衡、疏密相间的参差美，并由此构成了龙、凤、狮、虎四种栩栩如生的优美造型：龙类若舞若飞，潇洒俊逸，花儿内部短瓣紧抱，外部长瓣飘洒，像"龙盘蛇舞"；凤类亭亭玉立，婀娜多姿，花儿内部花瓣疏松或紧密内抱，外部花瓣自然下垂，如"天女散花"；狮类威武雄壮，魁伟挺秀，花儿大部分为匙状花瓣，且长短不一，相互重叠，排列参差，变化多姿，如"醒狮图"；虎类则刚劲沉稳，充盈丰满，舌状花瓣回心而抱，呈层瓦复叠状，似虎爪捕食，如虎啸长天。

③菊花不仅娇艳多姿，而且用途广泛。不仅它的花序是一味名贵中药材，其嫩茎、叶、根亦可供药用。此外，还能做成各种精美的佳馔，如菊花肉、菊花羹、菊花酒、菊花糖等。这些菊花食品不仅香味俱佳，而且营养丰富。再者，杭菊还是驰名中外的清凉茶饲料。至于那自古就有"虫见愁"之称的除虫菊，则是效力极高的天然杀虫剂。菊花还有保护环境、净化大气的奇异功能，被人们赞为"空气的卫士"。

菊花既有很高的观赏价值，又有广泛的实用价值，确是一种值得大力发展的珍贵花卉。
