Gypsophila paniculata (botanical name) or baby's breath has an improved variety called "Bristol Fairy" and is covered with double blossoms that are 1/4" wide. baby's breath blooms between july - october in the garden though florist's should have it year round.





Also, G. elegans an annual, has flowers that are 1/2" or more across in white, pink or rose colored flowers.
