A Russian mammoth sunflower is visually stunning not just for its size (they get to be about 8-10 feet and their head diameter can be over 12 inches), but because of its bright, happy color and large, umbrella-like leaves. The stalks are a good 3-4 inches in diameter. The Russian Mammoth sunflower can produce over one thousand seeds per head. It’s a very low maintenance plant, perfect for beginner gardeners. You can start the seeds indoors, or plant directly into the soil when it’s warmed, 1-2 weeks after last frost date. Grow in an open area, as they will need lots of space. These flower need full sun.
