Origin
The Phlebodium aureum 'Davana' is a type of fern that originally comes from the subtropical and tropical regions of America. It is also known as the 'Blue Star' fern due to the unique blue-green colour of its fronds. This plant is part of the Polypodiaceae family, which are spread throughout the world, but are particularly common in the tropics.

Characteristics
The Phlebodium aureum 'Davana' stands out because of its blue-green, shiny fronds, which can grow up to a metre in length. The petioles, also known as rachis, are covered with straw-coloured scales. The fern does not have flowers or seeds but reproduces through spores that form on the underside of the fronds. A notable characteristic of the Blue Star fern is its air-purifying properties: it helps to improve the air quality in the environment by converting carbon dioxide into oxygen.

Care
Taking care of the Phlebodium aureum 'Davana' is relatively straightforward. It thrives best in light to partial shady locations but should avoid direct sunlight to prevent leaf scorch. A high humidity is recommended for optimal growth, which can be achieved by regular misting. The soil should be moist but not drenched to prevent root rot. Watering should be reduced during the winter months. The plant periodically turns old foliage yellow and sheds it; this is a natural process and no cause for concern. However, it is advisable to regularly check the plant for pests and diseases to detect and treat them early.
