Calathea Northern Lights Care: How to Grow a Silver-Leaf Calathea

What is Calathea Northern Lights?

Calathea 'Northern Lights' is a compact clump of broad, oval leaves on deep purple stems. Each leaf has a wide silver-green center feathered along the veins, a dark green border and a purple underside, and on some leaves a thin pink line runs down the midrib. From above it reads as silver and green; when the leaves lift, the purple shows.

It's sold as a form of the rose-painted calathea, Goeppertia roseopicta, which most shops still label Calathea roseopicta. Missouri Botanical Garden and NC State Extension describe the species as having glossy, elliptical leaves 6 to 10 inches long, feathered in rose or creamy white, with reddish-purple undersides. NC State lists several named forms, among them 'Medallion', with silver-striped dark green leaves and purple undersides. 'Northern Lights' isn't on the extension cultivar lists we checked, so treat it as a trade name. Its silver centers and purple undersides fit the species.

In the wild, rose-painted calathea grows in the rainforest understory of western South America, in Brazil, Colombia, Ecuador and Peru. Indoors it stays small: Missouri Botanical Garden says it typically reaches 12 to 16 inches tall in a container, and NC State gives 1 to 2 feet tall and wide.

It belongs to the prayer plant family, and its leaves fold up at dusk and open again in the morning. Care comes down to four habits: bright shade, evenly moist soil, clean water and humid air. It's part of our Rare Plants collection, a collector plant grown in small batches that can sell out.

Why grow Calathea Northern Lights?

It's grown for its leaves, and it has a few practical points in its favor:

• Two looks in one plant. The silver tops face you during the day, and the purple undersides show when the leaves fold up in the evening.
• It stays compact. Missouri Botanical Garden puts it at 12 to 16 in tall in a container, so it fits a side table, a wide sill or a deep shelf.
• No direct sun needed. It wants bright shade a few feet from a window, not a spot in the glare.
• It can be divided. Once the clump fills its pot, the RHS suggests splitting calatheas in spring into sections that each have several leaves.

Is Calathea Northern Lights a good fit for you?

It suits someone who enjoys a small routine: feeling the soil every few days, keeping distilled water or rainwater on hand and adding humidity when the heat comes on in winter. NC State rates calatheas as a group as high maintenance and this species as medium. Either way, it rewards attention more than neglect.

Skip it if your only spot is a hot, sunny sill, if your home drops below about 60°F in winter or if you're often away for more than a week with no one to check the soil. Very dry winter air is hard on it too, unless you're happy to run a humidifier.

If you've never kept a houseplant, one of our easy houseplants for beginners is a gentler start. If you like silver-striped leaves, Calathea orbifolia has a similar look on rounder leaves, and the rattlesnake plant is another calathea with patterned leaves and the same basic needs.

Is Calathea Northern Lights safe for cats and dogs?

It isn't on the ASPCA's plant lists by name. When we checked the ASPCA's cat and dog lists in November 2026, there was no entry for 'Northern Lights', Goeppertia roseopicta or Calathea roseopicta.

The lists do include a general entry titled Calathea, with the scientific name Calathea spp. and no species named, marked non-toxic to dogs, cats and horses. They also list a few named calatheas, such as Calathea insignis, our rattlesnake plant, as non-toxic, and NC State Extension tags rose-painted calathea as non-toxic for cats and dogs. None of these is an ASPCA entry for this plant, and we only call a plant pet safe when the ASPCA lists the plant itself, so we show Northern Lights as not on the list.

Keep it out of reach of a chewer either way. Chewing any plant can upset a pet's stomach. If your pet eats some and seems unwell, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435. A consultation fee may apply.

Check every plant by its own name rather than assuming a whole family is safe. The rattlesnake plant is a calathea the ASPCA does list by name as non-toxic, and our guide to pet-safe houseplants covers the others in our range.

How much light does Calathea Northern Lights need?

Bright, indirect light, or what Missouri Botanical Garden calls bright shade. NC State recommends bright, indirect light for rose-painted calathea. In practice that means a few feet back from an east- or west-facing window, close to a north-facing one or behind a sheer curtain. Missouri Botanical Garden says it tolerates some early-morning or diffused sun but not full sun, particularly in the heat of the afternoon.

The RHS suggests a north- or east-facing window in summer and a south-facing sill in winter, when the sun is weaker. If your natural light is poor, a grow light helps.

Watch the leaves for clues. NC State lists faded coloring as a sign of too little light and scorch as a sign of direct sun, and the RHS says weak growth from low light is a common problem with Goeppertia. UF/IFAS Extension says calatheas tolerate indoor light as low as 75 foot-candles but grow best at 150 to 200, so a dim corner keeps it alive without keeping its silver bright. If your home runs dark, our low light houseplants guide covers plants that cope better.

Keep it warm and steady. NC State and Missouri Botanical Garden both put the ideal room temperature at 65 to 75°F, and UF/IFAS notes that temperatures below 55°F can cause chilling injury in calatheas. Keep it away from drafts, heating vents and cold window glass; NC State and the RHS both warn against sudden temperature swings.

How often should you water Calathea Northern Lights?

Water often enough that the soil stays evenly moist but never soggy. NC State says to keep it moist but not soggy or wet, and UF/IFAS suggests letting the surface dry slightly before you water. So feel the soil every few days and water when the surface feels just dry, rather than going by the calendar. A plant in a 4 in pot holds less soil than one in a 6 in pot and dries out sooner.

When it's time, water like this:

• Pour slowly at the base of the plant, not over the leaves. NC State links wet leaves and poor air flow to leaf spot.
• Keep going until water runs out of the drainage hole, as Clemson Extension advises, so the soil is moist all the way through.
• Empty the saucer or cover pot after a few minutes. Roots left standing in water rot.
• Use room-temperature water. Clemson suggests 62 to 72°F.

In fall and winter growth slows and it drinks less. Missouri Botanical Garden says to cut back on watering in winter, and the RHS suggests letting the surface dry before you water again without ever letting the soil dry out completely.

Water quality matters more here than with most plants. NC State recommends rainwater or distilled water because fluoride in tap water can brown the leaves, and UF/IFAS names fluoride as the cause of dead spots near the leaf margins. The RHS says calatheas tolerate tap water left to stand for 24 hours, but standing won't remove fluoride. Skip softened water: Clemson Extension says it adds sodium to the soil.

Too much water and too little can look alike. Clemson notes that wilting doesn't always mean a plant needs water, and UF/IFAS links wilted calathea leaves to drought or to root disease. Feel the soil before you reach for the watering can. Our guide to watering houseplants covers the basics for every plant.

Calathea Northern Lights care: humidity, feeding, cleaning and repotting

Humidity is the main challenge. NC State suggests keeping it above 60 percent for this species, while UF/IFAS says calatheas hold their looks indoors at 40 to 60 percent. A humidifier, a tray of wet pebbles or a bright bathroom all help. Keep the water below the tops of the pebbles so the pot never sits in it. Missouri Botanical Garden and the RHS both suggest misting too, but go easy, since NC State links leaves that stay wet to leaf spot.

Feed once a month from spring through summer with a houseplant fertilizer at half strength, as NC State suggests, and stop in fall and winter. The RHS gives April to September as the feeding season. More isn't better: UF/IFAS links browning along the leaf edges and tips to excess fertilizer.

Wipe the leaves now and then with a soft, damp cloth; NC State notes that dust slows photosynthesis. Cut fully yellow or brown leaves off at the base of the stalk with clean scissors.

Repot in spring once the clump has filled its pot. NC State suggests every 1 to 2 years and the RHS every few years. Choose a pot with a drainage hole one or two sizes larger and a mix that holds moisture but drains freely. NC State suggests a peaty, slightly acidic potting mix with perlite or vermiculite, and the RHS recommends peat-free houseplant compost. Spring is also the time to divide it: ease the clump apart so each piece has its own roots and several leaves, then keep the divisions warm, humid and moist until they grow, as the RHS advises.

What to do when your Calathea Northern Lights arrives

It comes already potted at the greenhouse, in a recycled eco pot in terracotta or black, so there's nothing to assemble. A few small steps in the first week help it settle:

• Open the box the day it arrives. Lift the plant out by its pot rather than its leaves, and take away all the packing, including any winter protection added for a cold-weather trip.
• Feel the soil. If the surface is dry, water until the soil is evenly moist and tip out any extra. If it's still damp, check again in a day or two.
• Put it straight into its long-term spot, in bright shade away from vents, drafts and cold glass. Calatheas dislike sudden changes, so try not to move it around while it settles.
• Give curled leaves a few days. After time in a dark box, some leaves may be creased or held upright, and most relax as the plant settles. Cut off any leaf that's torn or badly bent at the base of its stalk.
• Leave the pot alone. It can stay in the pot it came in through its first growing season, and if it arrives in fall or winter it won't need feeding until spring.

If it arrives damaged or declines in its first 30 days, we replace it. Our shipping page explains delivery times and the guarantee.

Calathea Northern Lights problems and how to fix them

Most problems trace back to water, dry air or light. Find the symptom:

• Brown tips or crisp edges: low humidity or fluoride, NC State says. Switch to rainwater or distilled water and add humidity. Damaged edges won't recover, so judge progress by the next new leaf.
• Dead spots near the leaf margins: fluoride, according to UF/IFAS. Avoid fluoridated water and fertilizers that contain fluoride.
• Curling leaves: low humidity or too little water, NC State says. Feel the soil first, then raise the humidity.
• Silver markings looking dull or faded: too little light. Move it closer to a window but keep it out of direct sun, and judge by the new leaves.
• Scorched brown patches: direct sun. Pull it back from the glass or add a sheer curtain.
• Yellow leaves: UF/IFAS lists too little fertilizer, overwatering and light that's too strong as causes. An old lower leaf yellowing now and then is normal.
• Drooping leaves and rotting stems: overwatering or cold, according to NC State. Let the surface dry before you water again, keep it warm and never leave the pot standing in water.
• Patchy, water-soaked areas on the leaves in winter: edema, which the RHS links to soil kept too wet. Water less often until spring.
• Fine webbing with speckled or yellowing leaves: spider mites, which the RHS lists among calathea pests. Rinse the leaves in the shower and keep the humidity up. NC State also lists mealybugs, scale and aphids, so check the undersides of the leaves now and then.
