String of Frogs
(Ficus pumila ‘Quercifolia’)
Intermediate Experience Level - “Easygoing… with a few tiny demands.”
Personality
An adventurous little wanderer with absolutely no intention of staying where you put it.
Water Needs
Prefers consistently lightly moistened soil, especially when growing in a terrarium. Because its leaves and root system are tiny, it can dry out much faster than larger houseplants.
Water when the very top layer of soil begins to feel slightly dry. It does not appreciate sitting in soggy soil, though. Constantly saturated roots can lead to rot.
Think: Damp woodland floor - not frog pond.
Light Needs
Prefers bright, indirect light. It can tolerate medium light, but growth may become slower or leggier. Strong direct afternoon sun can scorch those tiny leaves, especially when grown inside glass.
In a terrarium, place it somewhere that receives plenty of ambient light without intense sunlight shining directly through the glass.
Think: Sunlight filtering through a forest canopy.
Pet Safe?
No - Like other members of the Ficus family, String of Frogs contains a milky latex-like sap that can irritate the mouth, skin, and digestive system if chewed or eaten by pets. Keep it somewhere little paws and curious mouths can't easily reach.
Things to watch for
Crispy leaves - Usually means the plant became too dry or humidity is too low.
Yellowing leaves - Often a sign of too much water or soil staying soggy for too long.
Leaf drop - String of Frogs can be dramatic about sudden changes in moisture, temperature, humidity, or location.
Leggy growth - Those long stretches between leaves may mean it's asking for more light.
Terrarium takeover - It's tiny, but ambitious. Trim regularly if it begins annexing neighboring territories.
Spider mites & other tiny pests - Its miniature foliage can hide equally miniature troublemakers. Check underneath leaves occasionally.
Common questions
Q: Why are the leaves on my String of Frogs getting crispy?
A: Your frog may be thirsty! Crispy foliage usually points toward dry soil, low humidity, or both. Increase humidity and try not to let the soil completely dry out.
Q: Why are the leaves turning yellow?
A: Your frog may have accidentally moved into a swamp. Yellow leaves often indicate too much moisture or poor drainage. Let the soil breathe a little before watering again.
Q: Can String of Frogs grow in a terrarium?
A: Oh, absolutely. In fact, this is where it tends to shine. It loves the increased humidity and woodland-like environment of a terrarium.
Q: Does it actually climb?
A: Yes! Given the opportunity, its creeping stems can attach themselves to textured surfaces. It can trail beautifully too, so you can decide whether your frog is a climber or a dangler.
Q: Why isn't mine growing very quickly?
A: Check the light first. String of Frogs can survive in lower light, but bright indirect light encourages fuller, faster growth. Temperature and humidity can also affect its enthusiasm.
Q: Can I trim it?
A: Please do. String of Frogs responds well to pruning, and trimming helps keep it fuller and prevents one tiny plant from declaring itself Supreme Ruler of the Terrarium.
Q: Can I propagate the pieces I trim?
A: Yes! Stem cuttings can root when placed into moist growing medium and kept warm and humid. Suddenly, one frog becomes an entire frog army.
Plant Lore & fun facts
Despite the name, no frogs are involved.
Its tiny lobed leaves simply resemble miniature frog shapes to some imaginative plant lovers.
It's basically a miniature forest vine.
String of Frogs belongs to the same genus as much larger ficus plants and trees. This tiny terrarium creeper has some surprisingly impressive relatives.
It's a natural climber.
Like other creeping figs, it can use tiny aerial rootlets to cling to textured surfaces as it grows.
Those leaves aren't miniature by accident.
‘Quercifolia’ refers to the plant's oak-like foliage — essentially describing its tiny leaves as resembling those of an oak tree.
Terrarium lovers adore it.
Its miniature scale, creeping habit, and love of humidity make it especially useful for creating lush terrarium landscapes.
It can become a tiny menace.
Under ideal conditions, String of Frogs can grow surprisingly enthusiastically and may need regular trimming to keep it from overwhelming slower-growing terrarium companions.

popular varieties
“String of Frogs” is generally the nickname used for Ficus pumila ‘Quercifolia’, so you won't find dozens of true String of Frogs cultivars.
However, it belongs to a creeping-fig family with some lovely relatives:
Ficus pumila ‘Quercifolia’
The classic String of Frogs - tiny, lobed, oak-like leaves and a delicate creeping habit.
Ficus pumila ‘Minima’
Another miniature creeping fig with small leaves and a wonderful terrarium-friendly growth habit.
Ficus pumila ‘Variegata’
A variegated creeping fig with green leaves edged in creamy white. Larger than String of Frogs but equally charming.
Ficus pumila
The original Creeping Fig. Its leaves are larger and its growth much more vigorous - essentially String of Frogs' considerably more ambitious cousin.
