Firefern (Oxalis hedysariodes rubra)

This shrubby plant is an oxalis, but unlike others in the family, it has red foliage. Little yellow flowers contrast nicely against satiny wine-red leaves.

Light

Firefern needs a sunny window for its foliage to remain a rich red color.

Water

Keep soil evenly moist. Firefern resents soggy soil, so be sure pot has adequate drainage in bottom.

Special Helps

Use standard potting mixture. Like most houseplants, the main requirement is a porous medium to allow enough air to get to the roots. Feed sparingly; a light feeding every two or three months dhould be enough.
