Senecio crassissimus, the propeller plant, vertical leaf or lavender steps, is a succulent species of flowering plant in the daisy family Asteraceae, and is endemic to the island of Madagascar off the east coast of Africa.

This motion helps the leaves forestall the loss of moisture in hot environments.

[4] Its daisy-like inflorescence are yellow on a long stalk, 30-60 cm long, with scale-like bracts that are branched to the top into a loose corymb that hold 30 or more daisy-like heads.

[5] Drought tolerant, it grows well in full sun and is sensitive to overwatering, where it will become mushy.

Like many senecios, their growing season is in the winter, where would be dormant in the summer months.
