Callisia repens (turtle vine): care, propagation and toxicity

To care for a Callisia repens, place it in bright, filtered light, plant it in a well-draining potting mix, water generously while it is growing without leaving the soil waterlogged, and keep it above 10°C (50°F) all year round. This small trailing plant in the Callisia genus, sometimes misspelled “calissia” in garden centers, is sold in France as the turtle vine (plante tortue in French).

It forms a cushion of tiny, fleshy leaves, green on top and often purple underneath, that quickly spills over the pot. It is a close relative of inch plant: see our Tradescantia profile and our guide to indoor trailing plants.

This guide draws on Kew, the RHS (Royal Horticultural Society), and NC State Extension (North Carolina State University), including on a question about toxicity that is too often addressed inaccurately.

🌿 Why choose a Callisia repens?

Callisia repens is one of the fastest trailing plants for creating a full look: NC State Extension describes it as a fast-growing, low-maintenance plant whose stems root on their own at the nodes. Its leaves, up to 4 cm long, grow alternately and close together along the stems, forming a striking carpet.

It can be grown in a hanging planter, a bowl, or on the edge of a shelf, while cultivars variegated in pink or cream add a splash of color. And every cutting becomes a new plant: ideal for filling out a pot or sharing.

🔎 Callisia repens at a glance

According to Kew (Plants of the World Online, Callisia repens), Callisia repens (Jacq.) L. is an accepted name in the Commelinaceae family, published in 1762.

Its native range extends from southeastern Texas to tropical America, taking in Mexico, Central America, and the Caribbean; the species has been introduced to Florida, Louisiana, California, Bangladesh, and southeastern China. POWO lists Tradescantia callisia and Tradescantia repens among its synonyms, which explains its resemblance to inch plant.

The RHS Callisia repens profile describes it as a tender evergreen perennial with a mat-forming, trailing habit, growing 10–50 cm tall and spreading 50 cm to 1 m.

📋 Quick care facts

Essential growing guidance, gathered at a glance.

📍 Where to place a Callisia repens and when to bring it home

Place Callisia repens near a very bright window, protected from harsh sun. The RHS recommends bright, filtered light and a sheltered east- or west-facing position.

According to NC State Extension, it prefers bright, indirect light and tolerates 2–6 hours of direct sun, but two extremes quickly take their toll: too much shade makes the stems leggy, while intense sun scorches the leaves. The same source places its comfort range at 60–80°F, or around 16–27°C.

📍 Ideal spot: A hanging planter or high shelf in front of an east- or west-facing window, or set back a little from a south-facing window with a sheer curtain in summer.

🕰️ Best time: Spring, when the plant resumes growing; this is also the season the RHS recommends for root cuttings.

🌤️ Outdoors in summer: On a sheltered, partially shaded balcony, only when night temperatures stay above 10–15°C (50–59°F); bring it indoors at the first sign of cooler weather.

🪴 How to repot a Callisia repens, step by step

The RHS recommends a mix of two parts peat-free John Innes No. 2 potting mix and one part fine grit: the key is to use a rich but very free-draining mix. NC State Extension likewise recommends sandy, well-drained soil, or potting mix lightened with perlite, and notes that excess water causes root rot.

A pot with drainage holes, only slightly larger than the root ball, helps prevent the soil from staying wet for too long.

✂️ Everyday Callisia repens care

Callisia repens care comes down to light, water without overdoing it, and a little pruning. The RHS recommends watering generously during the growing season and applying liquid fertilizer once a month; its profile for the cultivar Callisia 'Turtle' also recommends keeping the potting mix just moist in winter.

The RHS also says that no pruning is necessary and that the plant is generally free of pests and diseases; NC State Extension does, however, list spider mites, aphids, and mealybugs.

💧 Watering: Check with your finger: once the surface has dried, water thoroughly, then empty any water left in the saucer.

🌱 Fertilizer: Once a month from spring to late summer, use a liquid fertilizer for foliage plants (RHS).

✂️ Pruning: Optional; trim excessively long or bare stems to keep the cushion compact.

🔹 Rejuvenation: If the center becomes bare, plant fresh cuttings back into the same pot to fill it out.

👀 Check for pests: Look on the undersides of leaves and around the nodes for fine webbing (spider mites), aphids, or cottony clusters (mealybugs).

🍂 Callisia repens through the seasons

From spring to late summer, Callisia repens grows quickly: water once the surface of the potting mix has dried, rather than following a fixed schedule, since watering frequency depends on light, pot size, and room temperature. In fall, space out watering and stop fertilizing.

In winter, the RHS recommends keeping the potting mix just moist, and its H1B hardiness rating means the plant must not be exposed to temperatures below 10–15°C (50–59°F); it can only stay outdoors in winter where temperatures do not fall below 10°C (50°F).

The Arizona State University plant library notes that a cold snap below 40°F (around 4°C) can damage it, even if it recovers once the weather warms up.

🌱 How to propagate Callisia repens

Propagating Callisia repens is almost effortless: NC State Extension recommends stem cuttings and notes that stems root easily at the nodes. Cut a stem a few centimeters below a node, remove the lower leaves, and insert it into light potting mix kept just moist, or let it root in a glass of water.

The RHS also mentions dividing rooted clumps and taking root cuttings, by cutting 6–7 cm from the tip of a root in spring. Its tip for a dense effect: plant several cuttings together in an 8 cm pot. To choose between water and soil, read propagating in water or potting mix.

🐛 Common problems: causes and solutions

A Callisia repens that becomes leggy, turns yellow, or rots is almost always signaling a problem with light or watering. Here are the most common symptoms, their causes according to NC State Extension and the RHS, and how to address them.

🎨 What plants pair well with Callisia repens?

Callisia repens shares its needs with other members of the Commelinaceae family: the wandering Jew or Tradescantia and Tradescantia 'Nanouk' make a colorful hanging display alongside it. To create a cascading plant corner, our guide to trailing plants compares species according to the available light.

We also offer it in plant arrangements, as part of a trio with a Cyperus and a Chlorophytum or a quartet with Chlorophytum, Maranta, and Nephrolepis. You can also explore our Callisia and other hanging plants.

⚠️ Is Callisia repens toxic to cats, dogs, and tortoises?

Yes, according to the most precise university source we found. NC State Extension classifies Callisia repens as toxic to pets and children if ingested, with moderate severity. The toxic compound cited is calcium oxalate, found in the flowers, leaves, sap, and stems.

Symptoms listed include nausea, vomiting, diarrhea, loss of appetite, throat swelling, and difficulty breathing or swallowing; the sap can also irritate the skin. Arizona State University also mentions calcium oxalates in the foliage, which it describes as irritating.

We couldn't find an ASPCA (American Society for the Prevention of Cruelty to Animals) profile for this species, so we don't describe it as non-toxic, despite the many sites that claim it is without citing a source. It is also sold as forage for tortoises and reptiles: NC State notes that rabbits enjoy its foliage, but that doesn't prove it is safe.

Ask a veterinarian who specializes in exotic pets before feeding it to them. If you have a cat, hang it out of reach or choose from our non-toxic plants for cats.

✅ Our expert tips for success

Growing a healthy Callisia repens comes down to four things: bright, filtered light, well-draining soil, moderate watering, and temperatures of at least 50°F. If anything goes wrong, first check the length of the stems (light), then how firm the leaves are (watering). Take plenty of cuttings to keep it dense, and keep it out of pets' reach, since NC State classifies it as toxic.

Outside cultivation, bear in mind that it escapes gardens easily in warm climates: NC State lists it as invasive in South Africa, China, and Cuba, while the Florida plant atlas classifies it as non-native in Florida, where the UF IFAS (University of Florida) assessment rates its cousin Callisia fragrans as “Caution” in central and southern Florida and advises preventing it from escaping cultivation.
