Calico Hearts (Adromischus maculatus)

Overview

Calico hearts is a small, slow, charming succulent whose thick, flattened, heart-shaped leaves are splashed with irregular chocolate-purple spots on grey-green, like painted pebbles. Compact and characterful, it is a lovely collector's succulent for a bright windowsill - easy to keep and easy to multiply from a single fallen leaf.

Origin & Natural Habitat

Adromischus maculatus comes from the Western and Eastern Cape of South Africa, tucked into rocky, well-drained crevices in bright spots. It is one of the most popular of the spotted adromischus group.

Appearance

Short stems bearing clusters of thick, flat, rounded-to-heart-shaped grey-green leaves, each irregularly blotched and spotted with dark chocolate-purple, and often edged with a fine wavy line. It stays small and slow, forming a neat, pebbly little clump. Slender spikes of tubular flowers can appear.

Why People Love It - Qualities & Benefits

People love the painted, spotted leaves (no two quite alike) the compact tidy habit, and the ease of care and propagation. It packs a lot of pattern and character into a very small pot.

Care

Light

Bright light with some direct sun keeps the leaves tight, well-coloured and boldly spotted - a sunny windowsill is ideal. Too little light and the leaves space out, pale and lose their markings.

Watering

Soak when the soil is fully dry, then wait; the leaves store water and soften slightly when thirsty. Water into the soil, not over the leaves, and keep drier in winter. It rots if kept wet, so err dry.

Soil & Potting

A gritty, free-draining succulent mix in a pot with drainage. Sharp drainage keeps the small roots healthy.

Humidity & Temperature

Warm, dry air suits it; it dislikes humidity. Ordinary dry room air is ideal; keep it above about 7-10°C.

Feeding

A much-diluted succulent feed once or twice in the growing season is ample for this slow little plant.

Repotting

Repot every couple of years in spring as the clump fills the pot. Handle gently, as the leaves detach easily, and settle into fresh gritty mix.

Propagation

Easy from leaf cuttings: a detached leaf, laid on gritty soil, forms roots and a tiny new plant at its base - though, like other adromischus, it can be a little slower than some succulents. Keep barely moist until established.

Common Problems & Pests

Overwatering rot is the main danger, made worse if water sits on the leaves. Leaves drop at a touch (they can propagate). Mealybugs can hide among the leaves. Stretching and faded spots mean too little light.

Toxicity & Safety

Calico hearts is generally considered non-toxic to people and pets, making it a safe little succulent to grow around children and animals, though it is best to discourage pets from chewing it.

Pros & Cons

Pros: beautiful chocolate-spotted heart-shaped leaves, compact and slow, easy to grow and multiply, non-toxic. Cons: leaves drop easily, needs good light to keep its markings, rots if overwatered, slow to bulk up.

Best Suited For

For windowsill collectors who love pattern and pebbly texture in a small, easy, safe succulent - a little painted gem for a bright spot.

FAQ

Why is mine losing its spots? Too little light - move it to a sunnier spot and new leaves come back boldly marked.

A leaf fell off - can I grow a new plant? Yes: lay it on gritty soil and it roots into a new plant, though adromischus can be a bit slower than other succulents.
