Cyrtomium sp

The Classic Forest Shield Fern

What Is Cyrtomium sp.?

Cyrtomium sp. refers to a fern from the Cyrtomium genus when the exact species is not specified. These ferns are often known as “holly ferns” because of their slightly pointed, firm leaflets.

Cyrtomium species grow naturally in shaded forest environments with moderate humidity. Unlike aquatic ferns, they are terrestrial or semi-terrestrial plants and should not be submerged in water.

They are valued for their structured, glossy fronds and their ability to adapt to indoor conditions better than many delicate ferns.

Strong and classic in appearance, Cyrtomium sp. is suitable for growers who want a hardy fern with clean, bold foliage.

How It Grows

This fern grows from a central rhizome in a clumping form. New fronds emerge upright and arch slightly as they mature.

Growth is moderate under stable conditions.

The Leaves (Fronds)

The fronds are firm and structured.

• Color: medium to deep green

The leaflets often resemble holly leaves in shape.

Too much sun may cause leaf burn.

Water & Growing Conditions

Care Level

Low to medium care.

Handling Note

Avoid overwatering and ensure good drainage. With stable moisture and gentle light, Cyrtomium sp. will maintain its firm, glossy fronds and structured forest appearance.
