Many types of annuals and perennials grow well in Florida, but their performance may not be consistent throughout the year, thanks to temperature fluctuations during both day- and nighttime. When temperatures are too low, many tropical plants won’t grow well, and when temperatures are too high, some will fail.

Here are two tough perennials that flourish in all parts of Florida:

Autumn fern (Dryopteris erythrosora) is among the many perennial ferns that grow well in Florida. Also called Japanese shield fern, its upright foliage reaches about 2 feet tall and wide. Its foliage is a bronze-copper color in spring when the plant is young, then matures to a dark green. Ferns are critter-resistant, and grow best in shade. For best results, keep the soil evenly moist.

Zeezee plant (Zamioculcas zamiifolia) is best known as a houseplant in the north, but can be grown as a tropical perennial in Florida. Its virtues abound: It grows slowly, attracts almost no pests, tolerates low-light conditions, and needs little water. The stalks of glossy leaves can reach 4 feet tall and 3 feet wide. Beware: All parts of the plant are poisonous if eaten.
