Tree Fern

The term "tree fern" encompasses various ferns that develop a trunk, elevating their fronds (leaves) above ground level. The most common species are from the genera Dicksonia and Cyathea.

Considerations for Pets

  • The text mentions that the trunk can be fibrous or woody, which might be attractive to some pets, but could pose a choking hazard if ingested.

Common Names

  • Tree Fern
  • Soft Tree Fern (specifically referring to Dicksonia antarctica)
  • Australian Tree Fern (can refer to different species)
  • Tasmanian Tree Fern (specifically referring to Dicksonia antarctica)
  • Hawaiian Tree Fern (H?pu?u, H?pu?u pulu)

Taxonomy and Nomenclature

  • Family: Dicksoniaceae (for Dicksonia antarctica) and Cyatheaceae (for some other tree ferns)
  • Dicksonia antarctica is a member of the Dicksoniaceae family, which consists of tree ferns.

Distribution and Habitat

  • Tree ferns are native to various regions, including Australia (Dicksonia antarctica grows from Queensland to Tasmania) and Hawaii (H?pu?u).
  • They thrive under the forest canopy in partially shaded, moist environments.
  • The Florida tree fern is native to the continental U.S.

Morphological Characteristics and Growth Habits

  • Tree ferns are perennials with fibrous, woody trunks.
  • Some species, like Cyathea cooperi (Australian Tree Fern), can grow to impressive sizes, with trunks up to 6 feet thick and 30 feet tall, and fronds reaching 8 feet in length.
  • Once mature (around 20 years old), tree ferns can produce spores for reproduction.

Quirky Facts

  • Tree ferns are described as recalling "an era of dinosaurs and volcanoes," indicating their ancient lineage and association with primeval landscapes.
  • Dead stems fall off, leaving oval scars.

Care Information

  • Tree ferns are best planted in spring.
  • Adding organic matter to the soil aids in establishment.
  • They prefer sheltered, moist environments and protection from full sun.
  • Watering is crucial, especially in sunny locations and during summer.
  • Winter protection is often necessary, involving wrapping the trunk and adding straw to the crown.
