A mix of Jolt dianthus colors grows in the landscape trials at LSU AgCenter Hammond Research Station.
Some of the best cool-season bedding plants we have available in Louisiana are interspecific dianthus, and the Jolt series dianthus is no exception. Jolt offers a more compact interspecific dianthus when compared to Amazon dianthus, which was named a Louisiana Super Plant in 2010. Moreover, Jolt dianthus is one of the most heat-tolerant interspecific dianthus we have, making it a perfect addition to your Louisiana landscape. Jolt dianthus will continue to bloom into the early summer months, giving you that extra push to carry your landscape into the warm season. Jolt dianthus can be planted in early fall in Louisiana landscapes. Like most bedding plants, they are susceptible to extreme freezing temperatures in the winter, so be sure to take appropriate actions if it gets too cold. However, Jolt dianthus can tolerate temperatures into the low 20s Fahrenheit. Jolts can be planted in late winter for an amazing pop of color throughout the spring and early summer. Aside from the striking bloom colors that come in Jolt Cherry, Jolt Pink and Jolt Pink Magic, Jolt dianthus has excellent dark green foliage that provides additional pop to the bloom color. Jolt dianthus makes wonderful cut flowers in flower arrangements. Jolt dianthus is also great for attracting butterflies in the later fall and early spring.
