But this Senecio is different. S. kleiniiformis, also from Southern Africa, has bright yellow blossoms the same shape and size as S. serpens. But they smell...good! A beautiful perfume of honey-lemon wafts from these all day. It reminds me of the honey-lemon drops people suck on during the winter to keep the flu away. Since we're having an awful influenza season, and an early one, S. kleiniiformis seems like a good plant to be growing on the windowsill. It's a tough and hardy plant that likes full to filtered sun, waterings when its soil dries out, and lots of admiring humans to smell its flowers.
