The perpetual plant (Red 10)

At the bus stop where I wait nearly every afternoon, there is a small plant--possibly a tiny tree--that has remained the same for years: same height, same flowers, same shape.

One day, thinking it was synthetic, I nipped a bit of leaf. It was real. I don't understand it's lack of growth. I don't understand flowers that never go to seed. I do know it's there and real.
