小花朱朱

小花朱頂蘭

小花朱產自阿根廷東北、巴西南部及巴拉圭沿河流域或者小溪之中，從低地到海拔達1,500米的沼澤地區。因此，小花朱是半水生或水生習性的朱頂蘭品種(之前已經介紹過另外的水生習性羽線朱: http://www.hkplants.com/viewthre ... &extra=page%3D1)。

小花朱看类似小粉紅朱(Eithea blumenavia)，但小花朱體积比較大，輕微粉狀覆蓋的深綠叶片是對生的。相反，小粉紅朱的光面叶片對生或向四方八面生長，並展示不同程度的網紋。

此種應該是在春天開花的，但在港栽培已經超过5年，这次是第一次來花但是奇怪地在冬季裡開花! 已我所知，小花朱在產地至少有7個主要不同個體。花分別有: 白底配明顯的粉紅色線紋、白底配暗粉紅色線紋、深橙红色、幾乎完全白色等。小花朱是自花不稔(self-sterile) 品種，它需要不同個體异花受粉才有機會結種子。

管理方面，小花朱喜歡全日照、潮濕温暖的生長環境，但在冬季必须經過最小2個星期低温(10度以下) 有助開花。介質方面，我完全用水苔或者含高機成份的植料，球根生長理想。特别注意粉蚧虫。因此，要經常進行害虫。

很漂亮~~ 是Traubia modesta嗎?

size有幾大架?

花色好清秀~ 係香港買的?

太驚訝了，怎麼會有這麼特別的朱花！
多謝樓主介紹，令我眼界大開！
請問樓主這是 Hippeastrum 孤挺花屬的嗎？

Budd:

Good guess, Traubia modesta does in fact look like Hippeastrum breviflorum but there are major differences between the taxa:

"modesta" is segments (petals) are narrow and sub-linear in shape; ovary inferior; and style very slightly recurved even at time of full opening of flower.  Besides, the flowers change colour from whitish with maroon markings at time of opening to almost mauve pink at time of fading.  Perianth tube almost absent.  Foliage is linear, slightly to moderately channeled, upright / semi-upgright.  Self-compatible.  It is a native to sandy hillslopes and rocky outcrops in Mediterranean climate (Climate Zone 5) in central Chile, thus following a winter-growing regime.  I attach a picture of my "modesta" which flowered last year below for your comparison.

"breviflorum", on the other hand, is straightly a summer-grower.  Segments are sub-oval shaped (i.e. segments are broadest in the middle and taper towards both end), segments with varing degree of feathery markings and are quite variable in colourings from mauve pink, rosy pink through reddish-orange to almost pearly white.  Style prominently recurved at time of maturity.  Ovary superior compared to "modesta".  Self-sterile.  Habit, habitats and growth please see my previous posting.

Comparison of size please see my reply to carmen below.

Hello Carmen and 黃臉婆:

這是孤挺花屬的。Hippeastrum breviflorum is a small species compared to most other species of the same genus.  Its foliage may reach up to 30 cm in length and about 2 cm broad.  Mature bulbs are no larger than 5 cm in diameter but they are usually no larger than 4 cm across.  Flower stalk may reach 50 cm (~ 60 cm) tall.  The short-lived flowers, which last for only about 3 days, are about (10 ~) 12 cm in diameter.

黃臉婆, you have got a good collection of Hipps.  I have been following your interesting posts.

Haren:

I introduced bulbs from southern Brasil.  As Hippeastrum breviflorum is a self-sterile species and therefore does not set seed by a single clone and that bulbs do not multiply readily, this species remain rare in cultivation.  Yet, I believe that it is cultivated as a garden subject by people in its native countries.

小花朱朱真是可愛，
花朵部分除了花蕊及花粉顏色像極了Eithea blumenavia。
我的小花朱長不大，下次也來換一下水苔種看看。

小花朱生長頗慢，給點耐性。你的球幾大？

我的球是兩年的實生苗，才一個小指頭大，葉子細長寬0.8cm，長約15cm。
之前以為小花朱生在水邊可能是半日照，把它放在陽台，每次就只有生兩片葉子，再來把它轉放在全日照環看看，盆子是否需要浸水？

連花瓣的質感都跟 Eithea blumenavia 好像...
