Appearance
The Bead Fern features delicate, finely cut fronds that are light green in color. The fronds are typically no more than 6 inches long and are supported by thin, black stems. The undersides of the fronds are covered in small, round, bead-like structures that give the plant its common name.

Care Guide
The Bead Fern is a relatively low-maintenance plant that is easy to care for. Here are some tips on how to care for your Bead Fern:
Water: Bead Ferns prefer moist, well-draining soil. Water your plant regularly, but be careful not to over-water, as this can lead to root rot.
Fertilization: Bead Ferns do not require regular fertilization, but you can add a small amount of slow-release fertilizer to the soil in the spring if desired.
Soil: Bead Ferns prefer soil that is rich in organic matter and well-draining. A mix of peat moss, perlite, and vermiculite is ideal.
Sunlight: Bead Ferns prefer bright, indirect light. Direct sunlight can scorch the delicate fronds.
Hardiness Zones: Bead Ferns are hardy in zones 3-8.

To prevent fungal infections, be sure to provide good air circulation around your plant and avoid getting water on the fronds.
