The Phlebodium aureum 'Davana', often called Blue Star Fern or Golden Polypody, is a beautiful houseplant that brings a calming, woodland atmosphere into your home. With its unique, highly curled leaves dressed in a striking blue-grey, this plant adds an elegant touch of nature to any environment. A fascinating feature of this plant is its fuzzy, golden-brown rhizomes (rootstocks), which often creep over the edge of the pot and resemble small paws. The vibrant blue-green color of the leaves is created by a fine wax layer, providing a beautiful, matte contrast to conventional green houseplants.

unique, highly wavy and curled blue-green leaves

Perfect for bathrooms with windows or bright hallways.
🌿 Care of Phlebodium Davana – Overview
This plant is not only a feast for the eyes but also easy to care for if a few needs are met. It is suitable for motivated beginners as well as experienced plant lovers and is significantly more robust than many other fern species.
🌱 Growth
-
bushy and sprawling
-
spreads via creeping rhizomes on the soil surface
-
can reach a height and width of about 40 to 60 cm when mature
-
contributes to a fresh, wild, and lively appearance.
🍃 Leaves
-
deeply lobed and, in the 'Davana' variety, highly wavy to curly
-
striking bluish-green, matte coloration due to a natural wax layer
-
soft, almost paper-like texture
-
form a dense, wild tuft reminiscent of a miniature jungle.
💧 Watering / Water
Like most ferns, Phlebodium Davana likes consistent moisture but not wetness.
-
keep soil consistently slightly moist
-
absolutely avoid dry root balls (quickly leads to crispy leaves)
-
best to water from below or from the side; do not water directly over the fuzzy rhizomes, as they can rot
-
water with low-lime, room-temperature water
-
waterlogging, however, quickly leads to root rot.
🌼 Fertilizing
-
from spring to autumn: every 2–4 weeks
-
liquid houseplant or special fern fertilizer at half strength
-
stop fertilizing in winter
-
over-fertilization can burn the delicate roots and lead to brown leaf edges.
🌱 Substrate
A loose, airy soil climate is important, as Phlebodium often grows as an epiphyte on trees in nature:
-
humus-rich
-
very well-draining
-
slightly acidic
-
A mix of high-quality potting soil, some perlite, and pine bark (orchid soil) works excellently.
🪴 Repotting
-
every year or every 2 years in spring, when the pot is heavily rooted
-
polypody ferns grow wide, so shallow bowls or wide pots are significantly more suitable than deep pots
-
The fuzzy rhizomes should not be buried deep when repotting; they should rest on the soil surface.
✂️ Pruning
Phlebodium Davana does not require regular pruning.
-
simply cut off dried or unsightly leaves at the base
-
do not apply formative pruning, as ferns unfurl their fronds completely
-
use clean tools to prevent infections.
🌱 Propagating Phlebodium Davana
Propagation is quite easy through division:
-
when repotting, carefully divide the root ball along with the rhizomes with a sharp, clean knife
-
each division should have sufficient roots and at least a few healthy fronds
-
place the divisions in fresh substrate and keep them slightly moist.
☠️ Is Phlebodium Davana toxic?
No – Phlebodium Davana is completely non-toxic.
-
safe for cats and dogs
-
safe for small animals
-
Similar to Maranta or Spider Plant, it is an absolutely safe option for all pet owners.
👉 You can place it anywhere your furry friends roam without concern.
🧠 Other Care Tips
Polypody ferns love elevated humidity but cope better with normal indoor air than many of their relatives.
-
Occasionally mist the surroundings with low-lime water, but it's better not to spray directly onto the leaves until they are wet.
-
Important: Avoid touching the leaves too often! This rubs off the fine, bluish wax layer, and the leaf will permanently turn green at that spot.
-
The plant loves temperatures around 18–25 °C and dislikes cold drafts or underfloor heating directly beneath its pot.
✅ Conclusion
With its extraordinary, bluish shimmering appearance and pet-friendly nature, Phlebodium Davana is an excellent choice. It brings a wild, slightly jungle-like structure to any room, is comparatively easy to care for for a fern, and creates a cozy, calm atmosphere. Let this beautiful blue companion enhance your interior!
