Damon Abdi of Louisiana State University's Hammond Research Station believes leopard plant (Farfugium japonicum)'s spring yellow flower spikes provide beauty to gardens.

Abdi says red hibiscus (Hibiscus coccineus) has bright red blossoms that stand out in summer gardens. This fast-growing spring plant should be pruned in late autumn.

In October, candy corn (cuphea micropetala) blooms glow orange and scarlet, explains Abdi. Cut back this plant in late winter to stimulate growth.

Abdi recommends cutting it back in late winter to facilitate spring growth. Pollinators love it. Divide and replant this fast-growing plant if it outgrows its habitat.

According to Chuck Pavlich, director of new product development at Terra Nova Nurseries, Heuchera 'Ginger Peach' is one of the fastest-growing heuchera cultivars in gardens.

Abdi describes rose verbena (Verbena canadensis) as a low-growing mounding shrub with abundant purple blooms from spring to October. It grows swiftly but blooms briefly.

Mounds perfectly and produces many blooms throughout the season. Summer garden appeal comes from the fast-growing perennial's robust re-bloom and vitality.
