Spilanthes plant
Spilanthes is a warm climate perennial, grown as an annual in our climate. It is colloquially known as "toothache plant" as its leaves and flowers produce a tingly analgesic effect when ingested - quite interesting actually - my tongue is tingling while writing this description after having tried the leaves. Like basil, pinch the tips to promote bushyness and continued flowering. Protect from cold. Don't overwater. Edible. In a 4" pot.
