Is it geranium or pelargonium?

According to a recent post on Gardenista, this would be a pelargonium. How about we call it just plain pretty?

It had been a while since I included geranium in my pots but when I saw this stunner at a plant sale at work I could not resist. I mean who can’t adore a stripe on a flower? I bought this hanging basket of geraniums/pelargoniums after first glance and have not regretted this impulse purchase. The flower petals are edged in a deep hot reddish pink with lighter pink petals. I know this isn’t technically a stripe but it pretty darn well poses for one at a distance and that just spells fun in any garden.
