S. aggregata is an interesting plant, with bright orange/red flowers freely produced on a tall inflorescence. The color of the flowers is somewhat variable, with some clones having yellow tones on the lobes. It can be somewhat sprawling when growing in lower-light situations. The foliage is often sticky, and strongly scented.

The variant S. aggregata ‘Pendulina’ is shorter growing and somewhat more sprawling. S. aggregata is the parent, with S. pusilla, of the popular hybrid S. ‘Tinkerbells’.
