Family: Crassulaceae

Origin, Description & Uses
Sedum pachyphyllum, commonly known as jelly bean sedum or blue jelly bean plant, is a succulent subshrub native to the seasonally dry regions of Puebla and Oaxaca in Mexico. This attractive plant forms low-growing mats or spreading clumps of thick, cylindrical, blue-green leaves that may develop pink or reddish tips when exposed to bright sunlight. In spring and summer, it produces clusters of small yellow star-shaped flowers that attract pollinators. Because of its drought tolerance, unique appearance, and ease of cultivation, S. pachyphyllum is widely grown as an ornamental in rock gardens, container plantings, succulent collections, green roofs, and water-wise landscapes.

Risks & Threats
Although Sedum pachyphyllum is not currently known to be naturalized in Hawaiʻi, it possesses traits that are cause for concern. Like many succulents, it can reproduce vegetatively from detached stems or leaves, allowing it to spread beyond cultivation if plant fragments are dispersed into suitable habitats. Its tolerance of drought and poor soils may enable it to establish in dry, disturbed environments where it could compete with other vegetation. While there is currently limited evidence of significant invasive impacts, ongoing evaluation is needed to determine whether this species could affect Hawaiʻi’s ecosystems. Caution is recommended when planting S. pachyphyllum, and gardeners should monitor for unwanted spread and properly dispose of plant material.

High Risk Traits:

• Native to tropical regions
  
• Congeneric (Sedum acre) is invasive
  
• Reproduces via fallen leaves and rooting stems
  
• Sold and traded as an ornamental

Low Risk Traits:

• Cold-sensitive (limited climate range)
  
• Not naturalized anywhere
  
• No weed records
  
• No spines, thorns, or toxins
  
• Narrow soil tolerance
