思在樹人

有沒有搞錯，要講初綠怎麼擺這一張圖片？這一張要拍的主角是背面哪一株蘆薈，剛好前景有兩品初綠，就拿來當引子好了。

初綠Agave attenuata, 這也敢拿出來獻寶！就是喜歡收集品種，是不是很普通，其實也不是那麼的重要。

這一篇原來要討論的主題是龍舌蘭的特徵，初綠有它的一定角色，老株的莖幹會露出來蠻長的一段，這也算蠻獨特的吧，但我原來的目標設定也還不是這個，我想要交代的是軟葉系！

這品和一般典型的初綠不一樣嗎？這是它的園藝栽培種，Ag. attenuata 'Boutin Blue', ，暫譯「布丁藍」，葉片比較綠，植株比較高大些，出自於漢庭頓Huntington.

老株一樣會有莖幹露出。這布丁藍在San Marcos Growers裡有很詳細的介紹：（網址：http://www.smgrowers.com/products/plants/plantdisplay.asp?plant_id=66）這段文章其實有不少訊息可以參考，英文也沒有很難，就請大家自己看一下。

This is one of the first blue selections from plants at the Huntington Gardens that were from the seed collected along a high rocky cliff at 7,200 feet in the Sierra de Manantlan by Myron Kimnack and Fred Boutin in 1970. Seedlings from these plants were originally distributed by the Huntington Botanic Garden (ISI#1442) in 1984. It is much bluer and has wider leaves than Agave attenuata and the flower stalk is erect where Agave attenuata droops over. Culture and growth patterns are otherwise similar to the species. In 2003 the Huntington Botanic Gardens announced that Agave attenuata var. nova (ISI#1442) and Agave attenuata 'Nova' (ISI# 9038) are the same taxon, though in fact the first plants offered in the nursery trade were seedlings, so really represented a grex group with many genetically unique individual plants that would allow for the potential for many separate cultivars that could be selected from them. ... In 2012 the Huntington Botanic Garden made their own selection of one of the original Myron Kimnack and Fred Boutin collected plants and had it reproduced by micropropagation (tissue culture) by Rancho Tissue Technologies and this plant has now been officially named Agave attenuata 'Boutin Blue'. 

這是在Montery圖書館前拍攝到的初綠，看起來也是布丁藍。

漢庭頓裡的縞斑品種。

這株縞得很美。

這株黃中斑的也不錯，但其實這種紋路的基因不穩定，很容易跑斑。

這是我買進來的黃中斑品種，這品似乎不能直曬太陽，我進了幾株，越種越小，目前收到比較陰涼的地方調養中。

這株也是軟葉的，它不是初綠，是俗名章魚的Ag. vilmoriniana.

這一品拍攝於漢庭頓，也是軟葉系的，如果我沒有弄錯的話，它是Ag. bracteosa, 我有幾株小株的，型態還沒有很出來。
