Plant: Magnolia acuminata/Cucumber magnolia 尖頭玉蘭

Magnolia acuminata, commonly called the cucumber tree, cucumber magnolia or blue magnolia, is one of the largest magnolias, and one of the cold-hardiest. The leaves of Magnolia acuminata are pointed at the tip and provide it with its name - 'acuminate' means tapering to a fine point. Magnolia acuminata is native primarily within the Appalachian belt.
尖頭玉蘭也叫漸尖木蘭,是最大的木蘭屬植物之一,也是最耐寒的木蘭屬植物之一。尖頭玉蘭的葉子頂端是尖的,因此得名。尖頭玉蘭主要原產於阿巴拉契亞山脈。

Notes for Magnolia acuminata 尖頭玉蘭筆記

  • Magnolia acuminata, commonly called the cucumber tree, cucumber magnolia or blue magnolia, is one of the largest magnolias, and one of the cold-hardiest. It is a large forest tree of the Eastern United States and Southern Ontario in Canada.
  • Magnolia acuminata is native primarily within the Appalachian belt, including the Allegheny Plateau and Cumberland Plateau, up to western Pennsylvania and New York.
  • In Canada, Magnolia acuminata is listed as an endangered species and is protected under the Canadian Species at Risk Act. In 1993 The North American Native Plant Society purchased Shining Tree Woods to preserve a stand of Magnolia acuminata, which is also known as "The Shining Tree".
  • Unlike most magnolias, the flowers are not showy. They are typically small, yellow-green, and borne high in the tree in April through June.
  • The leaves of Magnolia acuminata are pointed at the tip and provide it with its name - 'acuminate' means tapering to a fine point. The name "cucumber tree" refers to the unripe fruit, which is green and often shaped like a small cucumber; the fruit matures to a dark red color and is 6–8 centimetres (2.4–3.1 in) long and 4 centimetres (1.6 in) broad, with the individual carpels splitting open to release the bright red seeds, 10–60 per fruit. The ripe fruit is a striking reddish orange color.
  • Magnolia acuminata are excellent shade trees for parks and gardens, though they are not recommended for use as street trees.
  • It has been marked as a pollinator plant, supporting and attracting bees and butterflies. It is a host plant for butterflies, providing food during their larval stage.
  • 尖頭玉蘭也叫漸尖木蘭,俗稱黃瓜樹、黃瓜木蘭或藍木蘭,是最大的木蘭屬植物之一,也是最耐寒的木蘭屬植物之一。它是美國東部和加拿大安大略省南部的大型森林樹種。
  • 尖頭玉蘭主要原產於阿巴拉契亞山脈,包括阿勒格尼高原和坎伯蘭高原,直至賓州西部和紐約州。
  • 在加拿大,尖頭玉蘭被列為瀕危物種,受到加拿大《瀕危物種法》的保護。1993 年,北美本土植物協會購買了閃亮樹林,以保護一片尖葉木蘭林,這種木蘭也被稱為「閃亮之樹」。
  • 與大多數木蘭不同,這種花並不艷麗。它們通常很小,黃綠色,四月到六月生長在樹上高處。
  • 尖頭玉蘭的葉子頂端是尖的,因此得名。「尖頭」的意思是一端逐漸變細。「黃瓜樹」這個名字指的是未成熟的果實,它是綠色的,通常形狀像小黃瓜;果實成熟時呈深紅色,長 6-8 公分(2.4-3.1 英吋),寬 4 公分(1.6 英吋),單一心皮裂開,釋放出鮮紅色的種子,每個果實有 10-60 顆。成熟的果實呈現引人注目的紅橙色。
  • 尖頭玉蘭是公園和花園的絕佳遮蔭樹,但不建議用作行道樹。
  • 它被標記為傳粉植物,支持和吸引蜜蜂和蝴蝶。它是蝴蝶的寄主植物,為蝴蝶的幼蟲階段提供食物。
