I bought some seeds online from India, and throughout the growing process I was a bit doubtful if it was actually spilanthes since the leaf growth habit was slightly different than online images. Mainly because they weren't purplish, and the stems aren't as long. However, they did end up with yellow flowers that tingle when you eat them., but none of them have ever grown the trademark red dot of the "eyeball" flower. Is this not "Acmella Oleracea"? It does taste very grassy and not lemony as people described.
