Caladium Humboldtii – Miniature White-Speckled Caladium
Caladium humboldtii is a miniature tropical foliage plant with small, arrow-shaped leaves in dark green, mottled and splashed with white between the veins. It’s a true species from the rainforests of southern Venezuela and northern Brazil, and it grows from a tuber into a dense, compact clump, usually only 20–30 cm tall. Its dainty size and crisp patterning make it a charming indoor plant for small spaces through the warmer months.
Why You’ll Love It ✔️
✔️ Crisp green-and-white foliage – Small arrowhead leaves with bright white mottling give it a fresh, delicate look that stands out among larger plants.
✔️ Compact and space-saving – Its tidy clump suits windowsills, shelves, desks and terrariums, so you get caladium colour without the space a full-sized plant needs.
✔️ A species collector’s caladium – Most caladiums sold are hybrids, but this is a true wild species. It’s the miniature parent of many dwarf forms and a lovely point of difference in any aroid collection.
Care Tips
🌞 Light: Bright indirect light keeps the white markings crisp and the growth compact. Avoid direct sun, which can scorch the delicate leaves.
💧 Water: Keep the mix evenly moist during active growth and water when the top centimetre or two begins to dry. Don’t let it dry out completely, but avoid soggy mix, which can rot the tuber.
💦 Humidity: It prefers 60% humidity or higher. A humidifier helps prevent crispy leaf edges, and its small size makes it well suited to a terrarium.
🌡 Temperature: 20–30°C is ideal. Keep it consistently above 18°C. As temperatures drop in autumn, caladiums naturally go dormant and the leaves die back. Reduce watering, keep the tuber dry and warm over winter, and new leaves will return in spring.
🌱 Soil: Use a well-draining mix of coco coir, coco chip & perlite that holds some moisture without becoming waterlogged.
🌿 Fertiliser: Controlled-release fertiliser is already added to the potting mix. During spring and summer, add a balanced liquid fertiliser at quarter to half strength every few weeks. Overfeeding can dull the white markings, and you should stop feeding once the plant begins to go dormant.
🚫 Toxicity: Toxic to pets and people if chewed or eaten. Caladiums contain calcium oxalate crystals that can irritate the mouth and throat.
Also known as: Caladium argyrites, Caladium myriostigma, Podospadix humboldtii, Dwarf Caladium, Miniature Caladium, Mini White Caladium
A little gem for collectors who love their foliage small and striking.
A note on Caladiums: Caladiums vary naturally in colour, pattern, leaf size and shape. Even plants of the same variety can look quite different from one another, and from leaf to leaf on the same plant. Please treat our product images as a guide only. Caladiums are tropical plants and need consistently warm temperatures above 18°C to keep actively growing. When temperatures drop below this, they naturally go dormant and their leaves die back. This is a normal part of their growth cycle and doesn’t mean the plant has died. The tuber rests underground, and new leaves return when warm conditions come back.
We get a lot of questions about how our shipping works, so here’s a simple breakdown 🌿📦
Our shipping rates are charged per box, with each box able to fit up to 8 × 75mm potted plants.
As a general guide:
• 75mm pots make the best use of space, with up to 8 plants fitting in one box
• 100mm pots take up more space, so a box will usually fit around 3 plants depending on their size and shape
If your order requires more than one box, the website will automatically add the additional shipping charge.
For example:
• Up to 8 × 75mm plants = 1 box
• Larger 100mm plants use more box space and may reduce the total number of plants that fit in each box
