Adenium obesum ‘Red’ is a stunning tropical succulent shrub admired for its swollen, sculptural trunk (caudex) and brilliant red, trumpet-shaped flowers. Its exotic look makes it a striking centerpiece for sunny windowsills, patios, or warm indoor spaces. Though relatively low-maintenance, it thrives best with proper light, drainage, and a warm environment.
Ideal Light: Full sun (at least 4–6 hours of direct sunlight daily) encourages abundant blooms and a thick, healthy caudex.
Tolerates: Bright, indirect light indoors, though flowering may be reduced.
Avoid: Deep shade — insufficient light leads to leggy growth and fewer flowers.
When to Water: Allow the soil to dry out almost completely between waterings. Water thoroughly, then drain excess.
Frequency: Typically every 7–10 days during the growing season (spring–summer). In winter, reduce to once every 3–4 weeks.
Important: Overwatering is the most common cause of adenium problems. The thick caudex stores water — soggy soil leads to root rot.
Soil: Use a very fast-draining mix — cactus/succulent mix with added sand or perlite is ideal. Good aeration prevents rot.
Pot: Choose a terra-cotta pot with multiple drainage holes. Terra-cotta allows excess moisture to evaporate more easily.
Feed: Every 2–4 weeks in spring and summer with a balanced, water-soluble fertilizer diluted to half strength. A bloom booster (higher phosphorus) can promote more flowers.
Avoid: Fertilizing in fall and winter when the plant naturally slows down.
Prune: In early spring, trim back leggy branches to shape the plant and encourage bushier growth and more blooms.
Repotting: Every 2–3 years in late winter or early spring, just before the growing season. Move up only one pot size to avoid excess soil staying wet.
Humidity: Tolerates typical indoor humidity; thrives in dry to moderate air.
Temperature: Prefers 20–35°C (68–95°F). Protect from temperatures below 10°C (50°F), as cold can damage the caudex and leaves.
🌺 Spectacular Blooms: Vivid red flowers add a bold tropical touch to any space.
✨ Sculptural Beauty: The unique caudex and branching shape make it look like a living bonsai.
🏡 Drought-Tolerant: Stores water in its trunk, perfect for low-water gardens and busy plant owners.
🌞 Sun-Lover: Thrives in bright light, making it ideal for balconies and sunny rooms.
