Dianthus 'Rainbow Loveliness Improved Mixed'

Pink

  • NEW in 2013
With its raggedy jagged petals, all crimped and tassled, this is a dramatically different dianthus. Its gentle fragrance is much more appealing than some of the more overpowering clove-scented types. This is something very different for your borders and patio pots.
