Annual Each Strawberry Corn stalk produces two or more 2" - 3" long ruby red, strawberry-shaped ears on compact 4' stalks. Add height and architectural structure to the back of your flower border. At summer’s end, harvest the kernels for popcorn. Kids will love to watch the ruby red kernels magically turn white when popped! Save the stalks for fall decoration along with your pumpkins and gourds.
