Calathea Orbifolia vs Medallion: Which Handles Tap Water Without Brown Tips?
Calathea orbifolia vs medallion compared side by side. See how leaf shape, light needs, humidity tolerance, and difficulty differ to pick the right prayer plant for your home.
Calathea orbifolia and Calathea medallion sit on the same branch of the prayer plant family, but they play the game very differently. Orbifolia spreads enormous, silvery-striped leaves that can reach dinner-plate size on a single petiole. Medallion packs intricate burgundy-backed medallions into a tighter, bushier frame. Both fold their leaves at night, both sulk in dry air, and both get lumped together in the “fussy tropicals” category at garden centers.
The practical difference comes down to leaf surface area. Orbifolia’s oversized leaves lose moisture faster through transpiration, which means it punishes low humidity harder than Medallion does. Medallion’s smaller, thicker foliage holds up in conditions that would turn Orbifolia’s edges crispy within a week. That single trait cascades through every care decision you’ll make.
This guide breaks down exactly where these two calathea varieties diverge so you can pick the one that actually fits your space.

How to Tell Them Apart at a Glance
Turn the leaf over. That is the fastest way to distinguish these two plants from across a room. Medallion’s underside is a saturated burgundy-purple that flashes every time the leaves fold upward in the evening. Orbifolia’s underside is a muted silver-green, almost the same tone as the top surface.
Leaf shape is the second tell. Orbifolia produces round to broadly oval leaves with wide, pale silver-green stripes running parallel to the lateral veins. The pattern is subtle and elegant, like brushed aluminum. Medallion’s leaves are more elliptical, with a pointed tip and an intricate feathered pattern of dark green, light green, and cream that looks like a hand-painted medallion viewed from above.
Size seals the identification. A mature Orbifolia leaf can span 12 inches across, large enough to use as a fan. Medallion tops out closer to 8 inches on an exceptionally happy plant, with most leaves in the 4-to-6-inch range.
Light Requirements Compared
Both plants evolved on the forest floor in Bolivia (Orbifolia) and Ecuador/Peru (Medallion), where they receive dappled light filtered through a dense canopy. Indoors, that translates to medium indirect light for both, but they respond to mistakes differently.
Orbifolia’s broad, thin leaves are essentially solar panels optimized for low light. They capture maximum photons with minimal tissue investment, which is efficient in the shade but dangerous in direct sun. Even an hour of unfiltered afternoon rays can bleach or scorch the silver stripes. Position Orbifolia at least 5 feet from a south-facing window, or use a sheer curtain. A north-facing or east-facing window works well without any filtering. For a deeper dive into what these terms actually mean in practice, see our houseplant light guide.
Medallion handles light more flexibly. Its thicker, more pigmented leaves tolerate bright indirect light without fading, and it will even push out more vibrant coloring in brighter spots. The burgundy underside intensifies with good light, while the topside pattern develops sharper contrast. Medallion is still a shade plant at heart, though. It will scorch in direct afternoon sun just like Orbifolia; it simply has a wider safe range before damage occurs.
In too little light, both plants respond the same way: leggy stems, smaller new leaves, and washed-out patterns. If you notice the silver stripes on Orbifolia losing definition or Medallion’s pattern looking muddled, the plant is asking for more light, not less.
Watering and Humidity
This is where the two plants diverge most and where most people fail with Orbifolia specifically.
Orbifolia wants consistently moist (not wet) soil. The large leaves transpire heavily, and the root system is relatively shallow. When the soil dries out even slightly, those enormous leaf edges are the first to show damage: crispy brown tips that never heal. Use a chunky, well-draining mix and water when the top half-inch of soil no longer feels damp to the touch. Our guide on how often to water calathea covers the specifics.
Medallion gives you a little more room for error. Its smaller, thicker leaves lose moisture more slowly. You can let the top inch of soil dry slightly between waterings without seeing immediate damage. Medallion still won’t tolerate being bone dry, but it forgives a day or two of forgetfulness that would have Orbifolia throwing brown edges within hours.
Both plants are sensitive to chlorine, fluoride, and dissolved minerals in tap water. If your municipal water is heavily treated, use filtered water or let tap water sit overnight to off-gas chlorine. Fluoride doesn’t evaporate, so if your water supply has fluoride added, filtered or distilled water is the safer choice.
Humidity is the headline difference. Orbifolia genuinely needs 60% relative humidity or higher to keep its leaf margins intact. In most US homes during winter, indoor humidity drops to 30-40%. That is not a “your plant would prefer more” situation; it is an “expect crispy edges within two weeks” situation. A humidifier running near the plant is effectively mandatory for Orbifolia unless you live in a naturally humid climate.
Medallion prefers 50% humidity but tolerates the 40-50% range that many homes maintain without intervention. It will look its absolute best with a humidifier, but it won’t punish you with rapid edge browning if you skip one. Grouping it with other plants on a pebble tray is usually enough.
Size and Growth Habit
Orbifolia grows upward and outward. Each leaf sits on a long, upright petiole that can reach 2 to 3 feet tall. The plant forms a loose, arching rosette. It needs more floor space than you might expect because those big leaves spread horizontally. Plan for a footprint roughly 2 feet in diameter for a mature specimen.
Medallion stays compact and bushy. New shoots emerge from the base in tight clusters, and the shorter petioles keep the foliage closer to the pot. A mature Medallion rarely exceeds 18 inches in any direction. This makes it much better suited to shelves, desks, and small side tables where Orbifolia would overwhelm the space.
Growth rate is moderate for both. Expect 4 to 6 new leaves per growing season (spring through early fall) when conditions are right. Neither plant grows fast enough to need frequent repotting; every 18 to 24 months is typical, or when roots visibly circle the drainage holes.
Soil and Feeding
Both plants need a mix that holds some moisture without staying soggy. A standard houseplant potting mix with added perlite (roughly 2 parts potting mix to 1 part perlite) works for either species. Some growers add orchid bark for extra aeration, which is especially helpful for Orbifolia since its shallow roots are prone to rot in dense, waterlogged soil.
Feed monthly during the growing season (April through September) with a balanced liquid fertilizer diluted to half the label rate. Calatheas are light feeders. Over-fertilizing causes leaf tip burn that looks identical to humidity damage, which makes diagnosis confusing.
Common Problems
The problems are largely the same for both plants, but the threshold for damage differs.
| Symptom | Likely Cause | Orbifolia Response | Medallion Response |
|---|---|---|---|
| Brown, crispy leaf edges | Low humidity or underwatering | Rapid (days) | Gradual (1–2 weeks) |
| Yellowing lower leaves | Overwatering / root rot | Moderate risk | Similar risk |
| Faded or bleached pattern | Too much direct light | Very sensitive | Moderately sensitive |
| Curling leaves | Underwatering or cold draft | Common | Less common |
| Spider mites | Dry air + warm conditions | High risk (large leaf area) | Moderate risk |
Spider mites deserve a special mention. Both calatheas attract them in dry indoor air, but Orbifolia’s large, smooth leaves give mites more real estate to colonize. Check the undersides of leaves weekly, especially in winter when humidity drops. A strong shower rinse every few weeks helps prevent infestations before they start.
Pet Safety
Good news for pet owners: both Calathea orbifolia and Calathea medallion are non-toxic to cats and dogs according to the ASPCA. This sets them apart from many popular houseplants. If you are specifically looking for pet-safe houseplants with strong visual impact, either of these delivers without the worry.

→ Build Watering ScheduleWhich One Should You Choose?
The honest answer depends on how much you are willing to manage your indoor environment.
Choose Orbifolia if:
- You already own a humidifier (or are willing to buy one)
- You want a statement plant with oversized, architectural foliage
- You have a bright room with no direct sun, so you can place it several feet from windows
- You enjoy monitoring your plants closely and adjusting care proactively
Choose Medallion if:
- Your home humidity sits around 40–50% and you would rather not add equipment
- You want bold color (that burgundy underside is hard to beat)
- Space is limited and you need a plant that stays under 2 feet
- You want a prayer plant with a slightly longer leash on watering mistakes
If you are new to calatheas entirely, Medallion is the better starting point. It teaches you the rhythms of prayer plant care, including their sensitivity to water quality and light intensity, without the hair-trigger humidity demands that make Orbifolia unforgiving for beginners. Our calathea care guide for beginners covers the fundamentals that apply to both species.
If you have already grown other calatheas successfully and want to level up, Orbifolia rewards the effort with foliage that genuinely stops people in their tracks.
Frequently Asked Questions
Can I keep Orbifolia and Medallion in the same room?
Yes, and there are practical benefits. Grouping plants together raises local humidity through collective transpiration. Position Orbifolia closest to the humidifier (if you have one) and let Medallion benefit from the ambient moisture on the periphery.
Why are my Orbifolia’s leaves not opening in the morning?
Calathea leaves that stay curled or folded during daylight hours are usually reacting to cold, drought stress, or root damage. Check the soil moisture and make sure nighttime temperatures stay above 60°F. If the soil is wet and the plant still won’t open, inspect the roots for rot.
Is Calathea medallion the same as Calathea roseopicta?
They are closely related but not identical. The plant sold commercially as “Calathea Medallion” is Goeppertia veitchiana, while Calathea roseopicta (now Goeppertia roseopicta) is a separate species that includes cultivars like “Dottie” and “Rosy.” The confusion exists because nurseries frequently mislabel both.
Do prayer plants really move?
Yes. Both Orbifolia and Medallion raise their leaves upward at night through a process called nyctinasty. Specialized cells at the base of each petiole (the pulvinus) swell and contract in response to light changes. The movement is driven by water pressure changes in these cells, not by growth. You can see it happen in real time with a time-lapse camera, and it is visible to the naked eye if you check at dusk and again at dawn.
How do I know if my calathea vs comparison applies to Goeppertia?
All plants formerly classified as Calathea in the houseplant trade have been reclassified to Goeppertia based on molecular phylogenetic studies. Nurseries, plant shops, and most care guides still use “Calathea” because the name is better known. Both names refer to the same plants.
