Pin-stripe calathea

Leaves and their movement

The species is distinguished by mature dark green leaves with fine, pale pink-white stripes on the upper surface. The undersides have a purple hue, so the plant's appearance changes with the angle of the light and the position of its leaves.

Mature leaves can reach up to 60 cm in length. Young leaves are broader, oval, smooth, glossy, and bright green; the characteristic contrast becomes more pronounced with age.

• dark green upper surfaces with fine stripes
• a purple hue on the undersides
• leaves folding at night

As with other Goeppertia species, the leaves respond to changes in light and temperature: they rise or fold at night and open again at dawn. This is a normal daily response, not a sign of disease.

Origin and name

Its native range is southeastern Colombia and southwestern Venezuela. The species grows mainly in a humid tropical biome, where light filters through the forest canopy rather than reaching the leaves as direct sunlight.

It is still sold under the name Calathea ornata: this is an older botanical combination that has remained in use as a trade name since the species was moved to the genus Goeppertia.

The specific epithet ornata comes from Latin and means “adorned” or “decorated.” The name refers to the leaf pattern, not the flowers: indoors, the plant is grown primarily for its foliage.

Light and placement

The plant needs bright indirect light or partial shade. Direct sun dries out the leaves, causing dry patches and reducing the contrast of the stripes. This happens especially quickly in dry air.

• bright indirect light
• partial shade without deep shade
• protection from direct sun

In a spot that is too dark, the plant will not necessarily die quickly, but its appearance suffers: the stripes may look less distinct, and growth slows. Major changes in placement are best made gradually so the leaves have time to adjust to the new light level.

Watering, humidity, and potting mix

The potting mix should be moist but not waterlogged. Too little water causes the leaves to curl, while standing water around the roots creates conditions for rot.

Use soft water that is not cold—water left to stand, rainwater, or distilled water. A peat-based mix with perlite or vermiculite retains some moisture while allowing excess water to drain away.

Why leaves become damaged

The leaves are the first to show care problems. Dry edges, curling, or loss of contrast are more often related to water, humidity, cold, or light than to infections.

• curling—lack of moisture
• dry edges—dry air or a cold draft
• dry patches—too much direct sun
• yellowing—possible spider mites
• fading—insufficient light

If the problem appeared after a change in location, watering, or temperature, start by correcting the conditions. Damaged edges will not turn green again, but new leaves should develop more evenly with consistent care.

Repotting and rhizome division

Repot every 2-3 years or when the roots become crowded and the potting mix becomes compacted in the pot. This is also a convenient time for vegetative propagation by dividing the rhizome.

1. remove the plant from its pot
2. divide the root ball into sections with roots and leaves
3. plant the sections at the same depth
4. water after planting
5. place in a warm spot with indirect light

Avoid dividing the plant into very small sections: a weak division takes longer to recover after repotting. Afterward, keep the potting mix consistently moist and maintain humidity, with no cold drafts.

Flowering and pests

The species produces small white flowers in spike-like clusters. Indoors, flowering is not the main indicator of good health: the leaves respond much more noticeably to growing conditions.

• spider mites
• thrips
• mealybugs
• whiteflies
• scale insects

Pests are easier to spot on the undersides of the leaves and where the leaf stalks emerge from the rosette. Regular inspection is useful after a spell of dry air or when sticky, pale, or cotton-like traces appear.
