The lowly Four O'clock doesn't get much positive press these days. It's just too easy to grow, often becoming quite invasive. However, in the right conditions, it's a wonderful plant. Anyone can get it to grow, it comes in many different colors, most varieties are fragrant, and it comes back every year. It tends to come up all over, but the small seedlings are easy to pull up and either throw away or give to friends. Cut them back so they will be bushier and not flop over. Not to be missed if you have a fragrant garden, but be sure you get a variety that has fragrance. I think the white-flowered kinds would look wonderful in a moonlight garden. The blooms don't open until the evening, but they should be called Seven O'clock's down here because that's when they open up in Louisiana!
