The balcony observer's 295th report- Trimezia steyermarkii-3 (Rebirth) 黃扇鳶尾 重生

Why is the yellow fan iris also called Yellow Walking Iris in English? Because after flowering, the yellow flower in the sheath will grow small plantlets. This phenomenon is called "viviparous phenomenon" in botany. These plantlets would grow and the weight of the growing plantlets would make the flower stalk bow down until it touched the ground and the plantlets took root.

The “walking” plantlet would end up taking root some distance away from the mother plant (in some cases, it may have a significant impact on its survival).

為什麼英文裡,黃扇鳶尾又叫做 Yellow Walking Iris(黃色會走路的鳶尾)呢?因為花鞘內的黃花開完後會長出小苗,這種現象在植物學上稱為「胎生現象」。這些小苗將生長,並且生長中的幼苗的重量會使花莖向下彎曲,直到花莖接觸地面並且幼苗生根為止。

“行走”的小植株最終會在與母本植物相距一定距離的地方生根(這在某些情況下,可能會對其生存產生重大影響)。

Three flowers of the yellow fan iris grew from three branches of the same flower stalk. 同一花莖的三個分支開出三朵黃扇鳶尾花。

Three small plantlets grew from three flower sheathes a few weeks after flowering. 開花後幾個禮拜,三個花鞘長出三株小苗。

A few months later, plantlets grew taller. 幾個月後,小苗長高了。

I cut them out. 我把它們剪下來。

Short roots can be seen at the bottom of the plantlet. 小苗的底部可以看到短短的根芽。

A year later, I had five more pots of yellow fan iris (four pots for soil; one pot for water). The first one to the right is their mother who has split the basin. 一年後,我多了五盆黃扇鳶尾(四盆種土裡;一盆種水裡)。最右邊盆身已經裂開的是它們的媽媽。

A plantlet grows on the flower stalk. It is not like its sisters being picked and planted in the soil or water; on the contrary, I let it stay there. One year has passed and it seems to be a little malnourished. I don’t want to change it for the time being,

一隻小苗長在花莖上。它不像它的姊妹們被摘下來種到土裡或水裡;相反的,我讓它一直待在那裏。已經一年過去了,似乎有點營養不良。我暫時不想變動它。

A plantlet grows on the flower stalk.  I don’t know what will happen if I put it on for another year?
一隻小苗長在花莖上。我不知道再放一年會發生什麼事?
