Some of the best dianthus for Louisiana are the Amazon series. These are extremely prolific flower producers and can be planted in September through early November or in February through March. Flower heads are large and will last until mid-May in south Louisiana and until late May or early June in north Louisiana.
This series also has cut-flower potential. Removing old flower stalks encourages the continuation of the bloom season.
Flower colors available in the Amazon series are Rose Magic, Purple, Cherry and Neon Duo. Amazon dianthus are Dianthus barbatus interspecific hybrids.
