Microsorum diversifolium · Kangaroo paw fern

The fronds show the characteristic irregular, deeply lobed pinnae with wavy, undulating margins and rounded lobe tips, arising from a creeping rhizome visible trailing over the pot edge - classic growth habit for kangaroo paw fern. The sori are arranged in scattered round dots on the underside/visible through the leaf surface in rows, consistent with Microsorum. This differs from Phlebodium aureum (which has more regularly pinnatifid, blue-green glaucous fronds with smoother margins) and from Microsorum musifolium (which has broader, strap-like undivided or minimally lobed fronds, often with a crocodile-skin textured surface). The irregular lobing and narrower, more deeply cut segments with wavy margins here point more toward M. diversifolium rather than those two rejected IDs. However, I can't rule out other similarly lobed Microsorum cultivars/hybrids (e.g., Microsorum scolopendria or some Davallia species) with full certainty from this angle alone - a clearer shot of the sori pattern and rhizome scales would help confirm.

Light

Bright, filtered light to partial shade; can tolerate some direct morning sun but avoid harsh midday exposure.

Water

Keep soil or mounting medium evenly moist; water when the surface begins to dry, roughly every 5-7 days, reducing slightly in cooler months.

Nutrients

Light monthly feeding with a diluted balanced liquid fertilizer during spring and summer; skip in winter.

Repotting

Repot or divide every 1-2 years when the creeping rhizome outgrows its container; use a shallow, wide pot since roots stay near the surface.

Soil media

Well-draining, organically rich mix -- standard potting soil amended with perlite and bark works well; can also be mounted like an epiphytic fern.

Temp & humidity

65-85F; thrives in high humidity (50-70%+) -- mist regularly or place on a pebble tray in drier rooms.

Temperature range

🌡️ 65-85F

Humidity range

💦 50-70%+

Care group

🏷️ Bright & Humid

Toxicity

No known toxicity concerns; safe around pets and visitors.

Pests & diseases

Generally trouble-free; watch for scale and mealybugs, and guard against root/rhizome rot if kept too wet or in poorly draining media.

Propagation

Divide the creeping rhizome into sections with fronds and roots attached and pot separately; this is far more reliable than growing from spores.
