Oxalis Hedysaroides

What is the plant

Oxalis hedysaroides, known as the fire fern, is not a fern but a flowering perennial plant native to the Caribbean. It is a member of the woodsorrel genus that grows to 30 cm height and 10 cm spread. The plant gets its common name from the fact that its leaves, while starting green, turn a deep purple red with exposure to sun. Oxalis hedysaroides is a very mobile plant and will rotate its foliage significantly to follow the sun. At dusk, the plant can seem to quiver slightly as the red leaves partially close by folding in half.

How to Care for the Plant

Water
Average Water Needs; Water regularly; do not overwater
Pruning
To improve their appearance, you should prune out any brown or yellow fronds from indoor ferns.
Fertilizer
Ferns are relatively light feeders compared to many other foliage plants. They prefer a balanced fertilizer, such as 20-10-20 or 20-20-20, with micronutrients applied at approximately 200 ppm nitrogen. Too much nitrogen can cause tip burn on the roots and leaves if the plant becomes dry.

Additional

Poisoning most often occurs during late summer when other feed is scarce, or when animals are fed hay containing bracken fern.
