大花老鴉咀 large flowered thunbergia / blue skyflower (thunbergia grandiflora)

自己是市區人,有點愧疚,最初認識此花是在兵頭花園 (動植物公園)。嬌美茂盛的花朵,見於園內栽種園圃的矮小植物,不覺此是藤蔓植物。 後知後覺地,今年第一次欣賞到野外花盛狀況,才真正感受此植物的特性。 此常綠藤本原生於南亞及中國。全年開花,但以夏秋最盛。 大埔滘郊野公園山谷間,藍紫色瀑布漫山傾瀉,美極。 總狀花序,懸垂性,大花呈唇狀;花冠藍紫色,喉部淺黃色。按《樹木谷》所指,「大花老鴉嘴」名稱前半描述其花,後半比擬其果;果熟轉黑、張口。葉厚對生,葉形多樣,心型至卵形。 this vine is easy and pretty. it blooms in the tropic all year round. it is native to south asia, including bengal and india; as well as to china. for us the flowering seasons come spring and autumn. two of its chinese common names start with “large flowered”. that...

海埔姜 /單葉蔓荊 beach vitex (vitex rotundifolia)

香港的海岸植物,熟悉的有草海桐、黃槿、假菠蘿,最近認識了另一種。十一月底在東平洲正值開花時候,藍紫色唇形花,也有漂亮的葉,海埔姜 /單葉蔓荊 是也。 網上資料蒐集,有豐富的資源,美國、台灣、香港的植物網站都有記載。這多年生匍匐灌木,有指是夏威夷的本土植物,也有說原生於亞洲與澳洲。 中藥界以其果入藥,稱為「蔓荊子」。巧美的葉片,也成為人類的口腹之物,曬乾製成「埔姜茶」。還是將焦點回歸植物本身,葉的形態細膩精美:單葉對生,葉片倒卵形,頂端鈍圓,基部楔形,葉背灰白。頂生花序,藍紫色唇形花冠.。同場可見開始成熟的果子。此植物適應在沙質的土壤生長。  learnt about a species of coastal plant from a trip down at tung peng chou in late november. drawn by the pretty match of the delicate appearance of the leaves and blossoms of this sprawling shrub. description of the plant, quoting from missouribotanicalgarden.org, “broad-oblong to suborbicular leaves are blue green...

炮仗花 fire-cracker vine/flamevine (pyrostegia venusta)

過年遇著炮仗花,就是喜慶,不得不立文特表。此花常見,也就更要多認識。 此花原生於南美,但經已廣泛成為花園種植品種。 來到了亞洲中國人的地方,更被擁護為喜氣的象徵。事實是,春夏之間,此藤本植物一到花期,真的嘩啦嘩啦一發不可收拾地盛放,攀滿園地山坡。 觀其細節,深綠葉對生,部分葉會發展成三叉卷鬚。花筒橙紅色,橙黃花柱與花絲伸出。花絲絲狀,花藥叉開。花柱柱頭舌狀扁平。 flame vine or more commonly known in hong kong as fire-cracker vine is a south amercian native. this species however now is generally a garden species. in hong kong as well as being used in gardening, very often you see them in the wild. it was chinese new year holiday and...

路邊牡荊/黃荊 chinese chaste tree along roadsides

之前遇到的牡荊是一棵樹,高大,賞花要仰望。 最近在山邊路旁看到盈盈嫩綠葉叢當中,冒起淺紫美美伸展花串,覺得眼熟。拍照,回來查究,原來是同一植物。 看似草本的黃荊,成熟後是灌木或小喬木。植物的花玲瓏巧美,近看那密被細毛還像流蘇的舞衣。 this plant is blossoming away along roadside and hillside under hot bright summer sun. the bluish violet flower panicles look like small dancing fairies in tutu. it looks like a herbivore. this is actually a shrub or small tree i wrote here before. the low-lying posture deceives me while allowing me to...
