Asplenium dimorphum x difforme 'Parvati' aka 'Austral Gem'

Asplenium dimorphum x difforme 'Parvati' aka 'Austral Gem'

Asplenium dimorphum x difforme 'Parvati' is a hybrid fern with glossy, divided fronds and a compact mounded habit. Its firm, leathery fronds build a dense green plant with overlapping growth in a pot.

The plant forms a clump from short rhizomes, with fronds spreading outward and upward in overlapping layers. Each frond carries small, divided segments that create a lace-like outline, while the surface remains noticeably glossy and substantial.

Asplenium 'Parvati' key features

• Horticultural hybrid of Asplenium dimorphum and Asplenium difforme
• Glossy, divided green fronds with a firm, leathery texture
• Compact mounded growth from a short rhizome
• Warm-growing fern for steady substrate moisture

Asplenium 'Parvati' hybrid background

Asplenium dimorphum is native to Norfolk Island, while Asplenium difforme is recorded from eastern Australia, Norfolk Island and New Zealand. 'Parvati' combines parentage from this south-west Pacific fern group and is grown as a selected ornamental hybrid. Balanced moisture, warmth and airflow reduce dry frond edges and soft rhizome problems.

This hybrid builds a mound of divided fronds from the base. Mature plants can develop a lush, layered shape, especially when grown in a wide pot that gives the rhizome room to branch.

Asplenium 'Parvati' care guide

• Light: Provide medium to bright indirect light. Morning or late-day filtered light can be tolerated when the plant is acclimated.
• Watering: Keep evenly moist during active growth, then let excess water drain fully. The fronds are firm, but the roots still need consistent moisture.
• Substrate: Use a fine but airy fern mix with bark, coco fibre, perlite and a moisture-holding organic component. An open mix leaves air around the rhizome and reduces wet-root stress.
• Humidity: Average to moderately high humidity reduces crisping along the divided frond edges. A humidifier or plant grouping reduces dry, crisp frond edges during winter heating.
• Temperature: Keep above 15 °C, with steady room temperatures around 18–26 °C. Cold, wet substrate can damage the roots.
• Feeding: Feed lightly from spring to early autumn with diluted fertiliser. Use a weak fertiliser rather than a strong dose.
• Potting: A shallow to medium pot with good drainage leaves the clumping rhizome aerated. Repot when the plant becomes crowded or the mix breaks down.
• Grooming: Remove tired fronds at the base. Pulling can disturb the rhizome and fresh shoots, so use clean scissors.
• Propagation: Established clumps may be divided only when there are clear growing points and enough roots on each section.

Asplenium 'Parvati' common issues

• Brown frond tips: Check humidity, watering rhythm and mineral build-up. Trim only the damaged tips if the rest of the frond remains firm.
• Yellowing fronds: Overly wet substrate or weak root aeration is often involved. Check drainage and let the mix rebalance before watering again.
• Dry, crispy segments: The plant may be drying too far between waterings or sitting in hot airflow. Stabilise moisture and move it away from radiators.
• Sticky residue or speckling: Inspect the divided fronds closely for scale, mealybugs or mites, especially where segments meet the stem.

Asplenium 'Parvati' pot growth

Asplenium 'Parvati' fills wider pots with overlapping, glossy divided fronds. The mounded clump widens gradually, and the arching fronds are easiest to see in a slightly wider pot.

Asplenium 'Parvati' household safety

Asplenium 'Parvati' is generally treated as a non-toxic ornamental fern. Keep it away from repeated nibbling and remove shed or damaged fronds from the pot surface.

Asplenium 'Parvati' name and botanical background

Asplenium comes from the historic spleenwort name. The parent epithet dimorphum refers to two forms, matching the distinct frond forms associated with Asplenium dimorphum, while difforme refers to irregular or differently shaped form.
