Here is a great kid friendly flower…the sunflower. It is an annual flower so you have to plant it every year but you want to make sure that you plant it after the last frost in the Spring so that it will survive. The birds love this flower also and they can grow so tall…kids just love it. And some of the sunflowers you can get can be red if you prefer them instead of yellow. Kids just love to stand next to it…she which one is taller the flower or the kid! This is an easy annual to have success with!
