Saw a kid in the park grab a flower off a bush and eat it the other day. Was wondering what this was? I think I remember the flowers were red (bright red) and trumpet shaped, longish. It was growing from the ground, on the curved road I think somewhere behind or to one side of Lumpini Hall.

And what does it taste like? Obviously, didn't try myself...

if you are going back that way, take a photo and somebody maybe able to help you .

Sesbania grandiflora?
