Dianthus - A wonderful flower to use as borders.... Dianthus are considered an annual but many are perennials. Not sure why they label them as annuals..... Maybe so they can be offered in packs for more reasonable price than in quarts or gallons like most perennials. Add some to your garden and you will be happy you did.
This plant is super in cooler weather and can handle a mild frost and still keep going - It takes a freeze to knock it back for the winter
These will finish off at 6" - 10" height with 8" - 10"+ spread
This Variety of Dianthus can be grown as a Perennial
