Why Gardeners Love Wojo’s Jem

3. Low Maintenance
Once established, Wojo’s Jem requires minimal care. It spreads gently without becoming invasive, and pruning is simple if it starts to wander.
4. Multi-Use Plant
From hanging baskets to erosion control on slopes, this plant adapts to many uses. Its trailing habit works just as well cascading from containers as it does carpeting garden beds.
