美焰球繡球樹 sizzling rose of venezuela

看到這花球的人,無不著迷。花朵對人本來就有亮燈的作用,這大刺刺豔紅火球更翻滾人的官能。

植物源自南美委內瑞拉,她的濃豔南美風情讓她成為受歡迎的園藝品種,香港公園、兵頭花園、遮打公園都看到她們。臺灣稱之為寶冠木。

大红花球其實由總狀花序密生聚合成而成,一球可簇生多至五十朵小花。花後結莢果,莢殼疏生短柔毛,有絲絨之感。其實此樹的葉初生時又是一景,嫩葉枝有如柳蕠彎垂,呈淡褐斑駁纹彩,又是另一種探戈風情。但自然有序,此时是花果期,賞葉要待他時了。

rose of venezuela sets fire on flower admirers every beginning of summer. this venezuela native fearlessly stuns and dazes everyone with her flaming heads of flowers.

this plant is a treasure to gardener and garden-goers, because there are so many things to appreciate from – the flower of course; the velvety pods appear almost shy hanging not far from the intese inflorescences;

and the dreamy leaflets. it is not the right leaflet season, but i will definitely keep my camera ready and post it here when they put their “handkerchief” show on (note: this plant is also known as handkerchief tree;  other common names include scarlet flame bean). stay tuned.

繡球樹 rose of venezuela (brownea grandiceps) – familia: fabaceae豆科| subfamilia: caesalpinioideae 蘇木亞科| tribus: detarieae | genus: brownea 寶冠木屬| species: brownea grandiceps (source: species.wikimedia.org)

參考:

  • 香港禮賓府有一棵種植了多年。官方網頁也特別一提。
  • A slow-growing, small tree with very large heads of red flowers which hang beneath the foliage. The leaflets are aristate, having an elongated apex. Young leaves are mottled pale pink and greenish white, turning pinkish brown and finally uniformly green as they mature. The pods are velvety, and propagation is from seeds. Brownea grandiceps is recognisable from its long pinnate leaves with 12-18 pairs of leaflets and the pendulous bunches of young leaves are pale green, splashed and mottled in a reddish brown. The spotted handkerchieves are impressive enough, but the inflorescences are even more of a sight – dense, salmon-pink balls of 20 cm or more across. (source: toptropicals.com )
