Phlox are huge bunches of pleasantly scented, disk shaped flowers on top of branching stems. Fresh phlox’s must be cut or bought when two-thirds of their florets are open and the closed buds demonstrate good color and size, the ones that are cut before time, in the tight bud phase, may not develop. Old phlox have all the blossoms opened and several are already dropped. Older phlox would shed once handled. Phlox, with large clusters of sweet-smelling flowers, are a good addition to arrangements of big jazzy flowers, like peonies or roses.
