One of my favorite flowers of late summer has arrived! After growing to be a good 6 to 7 feet tall, they have opened up into beautiful bright blooms...I just love sunflowers. Each year I grow different varieties. This year, I planted two Russian varieties, Rostov and Mongolian Giant, in the front flower beds. I keep them pretty close together, so they don't grow to be super tall, but they help support each other and don't fall over in the wind as much if they are planted closer together and stay shorter. I figure seven feet is plenty tall enough!
