Senecio crassissimus
Vertical Leaf Senecio
Senecio crassissimus solves the heat problem by turning its leaves edge-on to the sun. Thick, flattened, oval leaves in powdery blue-grey, rimmed in purple, are held vertically on upright purple stems, so the plant presents almost no surface to the midday sky.
That gives it a hard graphic quality that suits gravel gardens and raised planters, and it holds the colour without irrigation once its roots are down.
