Pollination Info for Ostrich Fern (Matteuccia struthiopteris)

Ostrich ferns reproduce through spores rather than seeds. They are homosporous, meaning their spores are all the same size and have the potential to develop into either male or female gametophytes. Unlike most plants, ferns do not rely on pollinators to transfer pollen from the male to the female reproductive structures.

Instead, in the case of ostrich ferns, the male and female reproductive structures are located on different parts of the frond. The male structures, called antheridia, are located on the underside of specialized leaves called fertile fronds. These antheridia produce sperm cells that can be released into the environment.

The female structures, called archegonia, are also located on the underside of fertile fronds. They contain the eggs that are fertilized by the sperm cells. Once fertilized, the zygote will develop into a new sporophyte fern.

Wind plays a significant role in the dispersal of ostrich fern spores. The spores are released from the fertile fronds and carried by the wind to new locations. This form of reproductive strategy allows the fern to colonize larger areas as the spores can travel long distances before settling and germinating into new ferns.

Planting

• Choose a shady, moist location with well-draining soil.
• Plant in spring or fall, when temperatures are cool.
• Dig a hole that's twice the size of the fern's root ball.
• Place the fern in the hole and backfill with soil, gently tamping down.
• Water thoroughly.

Care

• Keep the soil moist, but not waterlogged.
• Mulch around the base of the fern to help retain moisture.
• Fertilize in spring and summer with a slow-release, balanced fertilizer.
• Divide the ferns every 3-4 years to prevent overcrowding.
• Trim back any dead or damaged fronds in the fall.

By following these simple guidelines, you can enjoy the beauty of ostrich ferns in your garden for years to come.
