It continued growing until it reached eighteen feet. It was blooming for about a month before some of the flowers started fading. They look like sunflowers, but they are only three inches across. They are sunflowers. Sunflowers come in a variety of sizes, shapes and colors.
Some new varieties have some outstanding color displays.
There are dwarf varieties that will stay shorter, but there are numerous plants with smaller flowers and large plants. They thrive in full sun. I love to grow various species of sunflowers. But, in the past I have started them inside and put them outside when they are about six inches tall, and bugs have eaten them down to where they are about one inch tall. I am desperate.
