White Alder, Politician’s Flower, White Butter Cup;  

– Commonly cultivated in Singapore.

-Very common plant in Chennai. Grows wild whenever it rains.



I WANDER’D lonely as a cloud
 That floats on high o’er  vales and hills,
When all at once I saw a crowd,
    A host, of  golden daffodils;
Beside the lake, beneath the trees,
Fluttering and  dancing in the breeze.
    Thus exclaimed the remarkable poet Wordsworth in his ode to the daffodils. We also had a similar experience when on our way to  Mahabalipuram. We zipped along enjoying the countryside when suddenly we noticed  these beautiful flowers by the roadside. Lying there, they seemed so happy and  cheerful that we could not ignore them. So we reversed and came to the spot  where they lay. Whipping out the camera, we proceeded to photograph them. And  here they are for your viewing
White Alder
Turnera subulata
Family: Turneraceae
28 Dec 2010

– Turnera subulata, naturalised undershrub originating from south America.

– What I found interesting on a nature walk ( at the Officers’ Training Academy, Chennai)  was the fact that the flowers were closed at dawn, opened later in the sun and were closed when it became cloudy again. Sun-loving  White Alder.

– This is a common weed in Chennai.   The whole play ground in Adyar used to be get covered whenever it rained.  No season for its flowering. Comes up very easily in cleared areas.
