These are bulbs planted in late spring to bloom in the summer. They are also called tender bulbs because they will not survive our winters. The two most common summer bulbs are dahlias and gladiolus. Both come in a wide range of colors.
They like rich, well-drained soil and lots of sun. After blooms finish in the fall, you can dig up these bulbs, dry them and store them in a mesh bag in a garage or basement to plant again next spring.
