Ruby Necklace
Othonna capensis
Updated Apr 8, 2026
Ruby Necklace (Othonna capensis) is a trailing succulent with bead-like leaves that turn ruby in strong sun, growing best in a gritty fast-draining mix with low, careful watering.
About Ruby Necklace
Ruby Necklace is a trailing succulent grown for its slender stems, bead-like leaves, and shifting color. In strong light, the foliage often moves from green into burgundy and ruby tones, giving the plant a more vivid and distinctive look.
Its habit is light and cascading rather than heavy, so Ruby Necklace works especially well in hanging pots, shallow bowls, and containers where the strands can spill over the edge. In lower light it usually stays greener and stretches more, while brighter conditions keep it tighter and more colorful.
Ruby Necklace behaves like a drought-adapted plant, storing water in its leaves and stems and preferring a root zone that dries quickly. With the right balance of sun, drainage, and restraint, it becomes a reliable trailing accent with strong texture and color.
How to Care for Ruby Necklace
Watering
Keep watering low. Let the potting mix dry out completely, then water thoroughly and allow all excess moisture to drain away.
Ruby Necklace handles short dry periods much better than constant moisture. Frequent watering or a slow-draining mix can cause soft leaves, collapsing stems, and root rot.
In brighter warmer periods, Ruby Necklace may need water a little more often, but only when the mix is truly dry. In winter or in lower light, extend the interval and keep conditions drier. Slightly less firm or faintly wrinkled leaves are often the safest sign that it is ready for a deep watering.
Sunlight
Provide full sun for the strongest color and the most compact growth. A sunny window or another very bright position usually suits Ruby Necklace best.
Outdoors, introduce direct sun gradually so the plant can adjust without scorching. In lower light, Ruby Necklace often stretches and stays greener, so stronger light is usually the first thing to improve if the ruby tones are fading.
Temperature
Aim for moderate temperatures around 64–77°F (18–25°C) for steady growth. Ruby Necklace should be protected from frost and from long periods of cold, especially if the soil is damp.
In very hot weather, airflow matters more than extra watering. Heat combined with wet soil can stress the roots, so stable warmth and bright light are usually the safest combination.
Humidity
Ruby Necklace prefers low humidity and good airflow. It does not need misting, and humid stagnant conditions can slow drying too much.
Normal household air is usually ideal for Ruby Necklace as long as the mix drains quickly and watering stays conservative. Rot risk increases most when humidity, poor airflow, and wet soil come together.
Soil
Use sandy, loose, very fast-draining soil. Ruby Necklace grows best in a cactus or succulent mix heavily improved with coarse sand, pumice, perlite, or fine grit.
Avoid dense peat-heavy mixes that stay wet for days. Drainage holes are essential, and terracotta can help Ruby Necklace dry more quickly between waterings.
