The Blue Star Fern (Phlebodium aureum) is gaining popularity for its bold, blue-green foliage, and because it’s easier to keep than many of its fussy cousins. Besides making a striking contrast with other houseplants, it’s a promising choice for anyone who hasn’t had luck with ferns and wants to try again. Let’s examine everything you need to know about Blue Star Fern Care to keep your plant healthy and looking great.


Growing to around a metre in height Phlebodium aureum differs slightly from plants we more commonly think of as ferns, such as Dryopteris filix-mas, due in part to its colour. Its wavy blue-green fronds vary between silver, grey and palest green and appear from creeping, hairy rhizomes (modified stems). The fronds are lobed and can grow up to 40cm. The round, bright-orange sori (clusters of sporangia, the structures that produce and contain spores) are arranged in two rows on each side of the midrib on the underside of the fronds. While repotting, gently tease out roots from the root ball. The number of divisions depends on the size of the parent plant and you can create as many sections as there are sufficient roots, rhizomes and leaves to support. Pot up each section in a free-draining mix and water in well. If the plant goes into shock remove any dying leaves and keep the plant in a warm, humid and light location. Wrapping the potted division in a clear plastic bag tied at the top with string creates humidity, reducing critical water loss.

Water when the surface becomes slightly dry. When watering, water the plant moderately and slowly from above, allowing water to soak through to the roots, then tip out any excess water. Water from the sides rather directly onto the leaves. Dry soil should be avoided. Reduce watering during the cold season. (Source: anselandivy.com)
