Sedum rubrotinctum R.T.Clausen
Jelly Bean Plant
Sedum rubrotinctum, commonly known as 'jelly bean plant', 'pork and beans', or 'candy cane plant', is a succulent in the family Crassulaceae described by R.T. Clausen in 1946, of probable Mexican origin although its exact wild habitat is debated. Its leaves are small, plump, and ovoid, bright green turning vivid red-orange at the tips when exposed to intense sun or cold, resembling candy-coated jelly beans. It forms dense clumps of semi-erect to prostrate stems 15–30 cm tall.

Overview
| Category | Classification |
|---|---|
| Family | Crassulaceae |
| Genus | Sedum |
| Growth Habit | Semi-erect to prostrate stems forming dense clumps, branching freely. Grows at a moderate rate and over the years produces extensive colonies. Leaves are very caducous on contact. |
| Conservation Status | Least Concern (LC). Widely cultivated; the exact wild origin has not been definitively confirmed, though Mexico is presumed. |
| pH Target | 6.0 – 7.0 |
| Type | Well-drained mineral soil, slightly sandy. Tolerates nutrient-poor soils. Avoid clay or peat-based soils. |
Origin & Habitat
Morphology
Alternate, ovoid to cylindrical leaves, 1.5–2 cm long, very fleshy. Bright green under normal conditions; under sun or cold stress, tips and margins acquire bright red to orange coloration. Surface smooth and glossy, without pruina.
ecoBright yellow, 5-petaled, star-shaped flowers grouped in terminal cymes. Blooms in winter–spring. Small but numerous and showy against the green-red foliage.
ecoFleshy, semi-erect stems, 1–5 mm in diameter, lignifying at the base with age. Branch freely and emit adventitious roots when in contact with substrate.
ecoFibrous and shallow root system capable of emitting adventitious roots at any stem node in contact with moist soil.

Propagation Strategy
- 1 Leaves detach easily; remove with a gentle pull.
- 2 Callous in a dry, shaded location for 24 hours.
- 3 Place on slightly moist substrate; mist every 3–4 days.
- 4 Roots and shoots appear in 2–5 weeks.
- 1 Cut stem segments 5–10 cm and callous for 24–48 hours.
- 2 Insert in dry or slightly moist substrate.
- 3 Water for the first time after one week; roots in 2–4 weeks.
Maximize sun exposure to obtain the most vivid red-green coloration.
Overwatering, which rapidly rots the fibrous roots.
Every 2 years in spring; this species prefers relatively small pots to control watering.
Cactus fertilizer at half dose, once in spring and once in summer; none in autumn–winter.
Uses & Applications
Precautions / Toxicity
TOXIC: Sedum rubrotinctum contains compounds that may cause nausea, vomiting, and diarrhea if ingested by dogs, cats, or humans, according to the ASPCA and veterinary records. Keep out of reach of pets and children. Contact with the sap may cause mild skin irritation in sensitive individuals.

Plant Health
Mealybug (Pseudococcus spp.): common at stem bases; treat with isopropyl alcohol or insecticidal soap.
Root rot from overwatering, especially in winter.

"The taxonomic status of Sedum rubrotinctum has been debated: some authors consider it a horticultural hybrid (possibly between S. pachyphyllum and S. stahlii) rather than a true wild species, which would explain the difficulty in locating confirmed natural populations. The intense red coloration of the leaf tips under UV stress is one of the most photogenic manifestations of anthocyanin accumulation in the genus Sedum."
