BTW, the reason I'm confused is my local nursery
center said that Martha Washington's love the sun. Dunno what to believe. What's true?

I would suggest you do a web search and key in the words martha washington pelargoniums this will give plenty of information.

I had M. Washingtons for a couple of yrs. They have such beautiful flowers. But when the heat came they almost completely stopped blooming. They started up again in Sept. I had read also that they didn't bloom much at all during the hot months, so I haven't bought any more since then. I had mine in full sun and it grew great but just didn't bloom during the heat. They just aren't heat lovers.
