The genus Diplazium is quite large, containing around 400 species of ferns. Ferns in this genus are mostly tropical but we have found a few temperate species suitable as garden ferns in the South.
More Information About Diplazium
The name Diplazium comes from "di" (two) and "plasion" (oblong) and refers to the double row of spore-producing sori on the underside of the fern fronds. Only a few scattered Diplazium species have enough cold tolerance to be grown here in our Raleigh, NC garden.
Diplazium species vary in size and growth form. Some are small and should be placed at the front of the border, while others are large and should be located near the back. Some are evergreen ferns and some are deciduous ferns. They are deer-resistant, too.
Like most garden ferns, Diplazium prefers partial shade and rich, well-drained, consistently moist, woodland soil. One species, Diplazium esculentum, is called the "vegetable fern" (the Latin "esculentum" means "edible") and the young fronds are used frequently in Asian cooking (Diplazium curry anyone?). Before switching over to a Diplazium diet, you should be aware that all ferns contain a carcinogen and should be eaten sparingly.
