1. Growing habits

Rhaphidophora foraminifera is a moderate to large, robust, densely leafy liana native to Sumatera, Peninsular Malaysia, and Borneo. It occurs at altitudes of 164-3396 feet (50-1035 m) above sea level on shaded granite or limestone rocks, moist hill dipterocarp, or disturbed forests.

Younger leaves are entire but become perforated as it grows into adulthood.

2. Growth rate and size

R. foraminifera is a fast-growing liana that can grow up to 49 feet (15 m) long. But at home, it may not grow as long, with most hardly going beyond 8 feet unless grown outdoors.

3. Rhaphidophora foraminifera leaves

It has oval to oblong-lance-shaped or oblong-elliptic, slightly oblique green leaves with few to numerous round to rhombic perforation covering up to ¼ the width of either side of the leaf blade. But younger leaves are entire.

Their feel is membrane-like to slightly leathery, and they have hairs on the upper surface while still young that shade as they mature. Also, the veins are hairy on the lower surface, a distinguishing feature.

How about their petiole? R. foraminifera has long, 8.7-20.5 inches (22-52 cm), smooth grooved petioles except for the prominent upper geniculum that is pubescent. The lower geniculum isn’t noticeable, and the petiolar sheath that goes to the upper geniculum degrades, leaving behind a little netted weak fiber.

4. Stems

This aroid has smooth, mid-green stems with internodes 0.4-2.8 (1-7 cm) long and slightly oblique to straight leaf scars. The prophyll and cataphylls decompose to form black mucilage. This mucilage forms parchment-like remnants on growing leaves, petiole, and inflorescences.

Last but not least, these stems also have dense aerial roots, i.e., dense clasping growing from internodes and nodes and robust feeding roots. But they don’t have flagellate foraging stems.

5. Flowers and fruits

A single or two large cataphylls that quickly deliquesce to a black mucilage subtend the inflorescence and seldomly a leaf. When the mucilage dries, it may adhere to the growing spathe.

The spathe is canoe-shaped, dull pale to dark yellow, and persists until the stamens mature. Afterward, it falls leaves a large scar on the spadix base.

On the other hand, the spadix has dull, greenish-yellow small inflorescence flowers that turn to dark green in the fruiting stage before ripening and greenish-yellow when ripe.

Variegated Rhaphidophora foraminifera mint and albo variegata

Besides the usual green form, there is the variegated forms, i.e., the albo and mint variegata, see Etsy.com.

1. Mint variegata

Rhaphidophora foraminifera mint variegata is the predominantly available form. This adorable plant has green perforated leaves with vibrant light green marbling, blotches, and sectors

Would you like to buy it? Then you must be ready to spend a fortune. Its prices range from $300 to $1500 for a cutting to an established plant.

2. Albo variegata

Rhaphidophora foraminifera albo variegata is less common. It has green leaves with cream to white blotches, marbling, or sectors.

Albo variegata: Check the latest prices.

Unlike the mint variegata that is more common, only a few people have this albo variegata. How much does it cost? If you need one, be ready to pay $300 to $600.

Rhaphidophora foraminifera care

Rhaphidophora foraminifera care is similar to the more popular Rhaphidophora species like R. tetrasperma, decursiva, korthalsii, hayi, or cryptantha.  

Here is how to care for your R. foraminifera:  

1. USDA hardiness zone

USDA hardiness zone for R. foraminifera is 11 to 12, i.e., these plants are not frost-hardy. Also, they cannot stand freezing temperatures. Only people in these zones can grow them outdoors all year.

2. Humidity

As tropical plants, they prefer high humidity but don’t mind average household humidity. We recommend keeping humidity at 50% or more.

If your home has low humidity, increase it by misting your plant a few times a week, having a pebble tray, and moving plants to humid rooms like the bathroom or kitchen. Also, you can put your plants together to create a micro-climate or buy a humidifier. Pure Enrichment® MistAire™ should work well.

3. Temperature

Their temperature range is 55 to 85 degrees Fahrenheit (12.8 to 29°C) but grows optimally at 70 to 80°F (21 to 27°C). Avoid sudden fluctuations, cold drafts, or heat stress. Also, don’t put your plant near heat-emitting vents like a radiator, room heating systems, or near air conditioning vents.

If outdoors, move your plant into your house when temperatures reach 50°F (10°C) as they won’t be growing.

4. Light needs

R. foraminifera needs bright, indirect light for about 12 hours a day. Avoid direct sun as it will cause sunburn. So, place them at a distance from the window where direct sunlight doesn’t reach them, especially on the south or west-facing windows.

On the other hand, low light will slow growth, making your plant leggy with smaller leaves that may turn yellow. Variegated plants are susceptible since the variegated part don’t photosynthesize.

We recommend using 10,000 to 20,000 lux (1000 to 2000 footcandle) grow lights if your plant is in a poorly lit area.

5. Best soil mix

The best soil for Rhaphidophora foraminifera should be airy, well-drained, and high in organic matter. A slightly acidic potting mix of pH 6.1 to 6.5 is best, but one neutral (pH 6.5 to 7.3) will also work.

Buy an aroid mix or make yours. A good blend should have perlite or pumice, coco coir/peat moss, bark chips/coco husks, and compost. You can also add charcoal and sphagnum moss.  

6. Watering

They love moist soil. Soggy soil will cause root rot. So, we recommend watering Rhaphidophora foraminifera after the top 1-2 inches of the soil feels dry.

It may be a few days to a week in the growing months and biweekly in non-growing. But since water needs vary with conditions and many other factors, first test the soil

Water your plant by slowly saturating the soil until excess water flows from drainage holes. After 15 minutes, discard any that collects in the cachepot or saucer.

7. Feeding

During the growing months, feed your plant once a month with an all-purpose, balanced, liquid houseplant fertilizer at half strength.

Don’t feed in fall or winter. But you are free to use slow-release fertilizer for potted houseplants. Start applying in early spring and follow what the manufacturer recommends.

8. Pruning

Routinely cut dead, damaged, or diseased parts with sterilized gardening shears. To keep the shape, size, or growth you want, you can trim some branches during the growing season, especially early spring.

9. Repotting

Repot yearly during spring or early summer or if rootbound when actively growing. Once it’s the size you need, you can repot less frequently unless rootbound. When repotting, go for a pot 2-3 inches wider in diameter.  

10. Staking

As a climbing liana, we strongly recommend that you provide and train your plant on a  climbing trellis, totem, or moss pole.


As you grow Rhaphidophora foraminifera, you may encounter a few problems. Let us now look at some of these issues and possible causes.

PestsUncommon indoors but may occur. Common pests are spider mites, thrips, scale insects, whiteflies, aphids, and mealybugs. Use insecticidal soaps, neem oil, or horticultural oil sprays to treat them.
Fungal and bacterial leaf spots and diseasesNot prevalent with proper sanitation. But fungal and leaf spots may occur. Signs include brown or black lesions on leaves and stems
Root rotOverwatering is the leading cause. Signs include yellow leaves, wilting, mushy base, black or brown mushy roots, etc. If it hasn’t affected the whole plant, repot it, removing the decayed parts. Also, ensure you water your plants well, and your potting mix drains.
Leaves turning yellowMost likely a sign of overwatering. But it may be due to too little light, too much light, cold drafts, nutritional deficiencies, etc.
Brown tips and edgesBrown tips and edges are a likely sign of leaf scorch due to underwatering, low humidity, too much light, or heat stress. Also, it may occur due to overfeeding, transplant shock, etc.
Leaves browning and brown spotsThe most likely cause of brown spots are pests and disease but overwatering many cause brown splotches and cold draft overnight browning.
Leaves turning black or having black spotsIndicates pests or diseases and rarely frost damage or overwatering.
Leaves curlingIt occurs to prevent moisture loss from leaves or prevent it from damage. Likely causes include underwatering, low humidity, too much light, heat stress, repotting stress, rootbound, etc.
DroopingPlants droop when cells don’t have water to keep them rigid. The leading causes are a thirsty plant, low humidity, heat stress, and too much light. But root rot, overfeeding, and other things can be causes.
