Lace fern

Lace Fern (Microlepia strigosa)

The Lace fern, Microlepia strigosa, is a species of fern native to moist areas of East Asia, Southeast Asia, Australia, and Polynesia. It is also naturalized in some parts of the Americas, including Hawaii and Florida. Characterized by its delicate, lacy foliage, it is a popular ornamental plant, both indoors and outdoors in suitable climates.

Description:

The Lace fern is a terrestrial fern, meaning it grows in soil. Its fronds are finely divided, creating a textured, feathery appearance that gives it its common name. The fronds can reach lengths of up to 2 feet (60 cm) or more, depending on growing conditions. The rhizome (underground stem) is creeping, allowing the fern to spread and form colonies. The color of the fronds ranges from light green to a more vibrant, darker green.

Cultivation:

Microlepia strigosa thrives in moist, well-draining soil and prefers partial shade to full shade. It is not tolerant of direct sunlight, which can scorch the fronds. Regular watering is important to keep the soil consistently moist, but overwatering should be avoided to prevent root rot. The fern benefits from high humidity. In cooler climates, it can be grown as a houseplant, requiring similar conditions of moisture, shade, and humidity. Propagation is typically done through division of the rhizome.

Varieties and Cultivars:

Several varieties and cultivars of Microlepia strigosa exist, offering variations in frond size, shape, and color. These cultivars are often selected for their enhanced ornamental value.

Ecological Considerations:

In its native range, the Lace fern plays a role in forest understory ecosystems. However, in areas where it has become naturalized, it can sometimes be considered invasive due to its ability to spread rapidly.

Common Problems:

Common problems encountered when growing Lace ferns include:

• Dry air: Dry air can cause the fronds to turn brown and crispy.
• Overwatering: Overwatering can lead to root rot.
• Pests: Common fern pests such as mealybugs and scale may infest the plant.
• Sunburn: Exposure to direct sunlight can cause the fronds to scorch.
