It’s Wedelia …. but it does look very much like a sunflower and why not it belong to the sunflower family. Wedelia can be catagorise as weed – plant and wildflower. For me they’re creepers too. My uncle brought it from Bangalore (Bengaluru) – it is not that it cannot found in Delhi but he liked the yellow flower and brought a small plant for me. This year i have repoted it in a bigger pot  …. it also has a story – it is a clay pot in which sweet curd are bought from sweet shop. Well it’s Friday and so a yellow flower from my garden.
