Calathea ‘Fusion Yellow’ is a striking variegated prayer plant known for its marbled yellow, lime and deep green foliage. A cultivar of Calathea lietzei (often still sold under its former botanical name), this variety offers bold painterly patterns with a contrasting purple underside.

Each leaf looks uniquely splashed and streaked, with bright yellow tones weaving through rich green sections. Like other Calatheas, it gently raises and lowers its leaves in response to light — earning the common name “prayer plant”.

While undeniably beautiful, ‘Fusion Yellow’ prefers stable conditions and consistent care.

Care Guide

Light

Bright, indirect light is ideal.

• East-facing windows are perfect

• Avoid direct sunlight — can fade or scorch variegation

• Too little light may dull colour and slow growth

Filtered light keeps foliage vibrant.

---

Watering

Calatheas prefer consistently moist soil.

• Water when the top 2–3cm feels slightly dry

• Do not allow the soil to fully dry out

• Reduce watering slightly in winter

Tips:

• Use room-temperature water

• Rainwater or filtered water is best (sensitive to minerals)

• Ensure good drainage

Overwatering or letting the plant sit in water can cause root rot.

---

Humidity

High humidity is essential.

• Ideal range: 60–80%

• Benefits greatly from a humidifier

• Avoid placing near radiators or heaters

Low humidity commonly causes:

• Brown, crispy edges

• Curling leaves

---

Temperature

• Ideal: 18–26°C

• Avoid temperatures below 16°C

• Protect from draughts and sudden temperature changes

Calatheas dislike cold stress.

---

Soil & Potting Mix

Use a moisture-retentive but well-draining mix:

• Peat-free houseplant compost

• Perlite

• A small amount of coco coir

The soil should stay lightly moist but airy.

---

Feeding

Feed during spring and summer:

• Balanced liquid fertiliser every 4 weeks

• Dilute to half strength

• Do not feed during winter dormancy

Overfeeding can cause leaf tip burn.

---

Growth Habit

• Compact and bushy

• Typically reaches 30–50cm tall

• Produces new leaves from the centre

Leaves move slightly throughout the day in response to light.

---

Common Problems

Brown leaf edges

• Low humidity or mineral-heavy water

Curling leaves

• Underwatering or dry air

Yellowing leaves

• Overwatering

Faded colour

• Insufficient light

Calatheas are often described as “dramatic” — they respond quickly to environmental stress but recover well once conditions improve.

---

Styling Ideas

• Perfect for brightening neutral interiors

• Pairs beautifully with dark foliage plants

• Ideal for plant cabinets or humid rooms

• Looks stunning in white or stone-coloured pots

Toxicity

Calatheas are generally considered non-toxic to pets, making them a safer option for cat and dog owners.
