Sweet story Sharon!
I love mine, I have them popping up here and there every year, easy to pull where you don't want them. Most get nice branching so if you planted several next to each other, they would make a nice mass of color.
Most are in the 4-5 ft height range but I have one that popped up next to my blue eucalyptus and it's about 8 ft. tall, almost like it's trying to keep up or compete with the tree!
