Red Maple in Mapleton, Boulder
北美常見的楓樹有十多種,賞楓地點還是以加拿大、美東為最佳地點,女兒家居科羅拉多,該州較有名的觀賞植物是Aspen(白楊木),楓樹則不甚有名,賞楓季節是在每年的十月份;科羅拉多州可能是土質、氣候的因素,楓樹並不很普遍,成林老樹更是少見,以下分四篇簡單介紹我今年在丹佛北邊小城Boulder所拍攝的四種楓樹~挪威楓(Noway maple)、銀楓(Silver maple)、紅楓(Red maple)和糖楓(Sugar maple)。
至於小城Boulder的賞楓景點請瀏覽我之前的部落格文章“2012楓紅在Boulder, 科羅拉多”
紅楓(Red maple)
美國紅楓(Red Maple)拉丁名為Acer rubrum,又稱為Swamp、Water或Soft Maple,它不同於在生長在亞熱帶,在中日台常見的紅楓(Acer palmatum cv. Atropuceum),我們常見的紅楓又名紫紅葉雞爪,是槭樹科、槭樹屬雞爪槭(A. palmatum)的園藝變種,此紅楓為落葉小喬木,高一般不超過10公尺。
美國紅楓(學名:Acer rubrum L.),原產美國東海岸,主要來自於美國北部以及加拿大大部分地區,是落葉大喬木,生長較快,成樹可長到60呎(18公尺)高,冠幅廣達12公尺,能適應多種範圍的土壤類型生長。

秋季葉子轉變成亮麗的紅色。它用於作為行道樹和遮蔭樹。

這棵位在Mapleton Elementary School校園內的紅槭(Red maple)是Boulder的珍貴老樹,往年這時節整棵樹葉子轉為通紅是Boulder一大景點;



Mapleton School原是一所小學,創立於1888年,由於該社區是老社區或是跟台灣少子化的相同命運,該頗有歷史的名校在2003年還是逃不掉關門的命運;現在該校已轉型為“early childhood learning center”,改變為一所“Preschools”,校園經大加整修後,這顆原本枝葉茂盛的紅槭被修剪成這副模樣,實在可惜!
