How to Choose
When selecting a Senecio that blooms in spring, consider the plant’s growth habit (trailing, upright, shrub-like), the climate of your area, and the light conditions available. Succulents like Senecio mandraliscae and serpens thrive in full sun and dry conditions, while varieties such as Senecio articulatus may prefer partial shade. Also, think about the space you have—trailing types like String of Pearls are perfect for hanging pots, whereas larger species like Barberton Groundsel suit open garden beds. Lastly, assess your watering routine and soil drainage, as Senecios generally demand well-drained soil and infrequent watering to avoid root rot.
