[edit] Description

Senecio crassiflorus is not an upright herb, the silvery to white woolly 20 centimetres (7.9 in) to 50 centimetres (20 in) tall plant tends to "lay down and rest" on the dunes and sandy coastal areas it inhabits.

Leaves
Shaped like spatula with roundish, long, narrow, linear bases to having a broad rounded apex and a tapering base. Mostly 4 centimetres (1.6 in) to 8 centimetres (3.1 in) long, .6 centimetres (0.24 in) to 2 centimetres (0.79 in) wide. The edges are smooth or toothed towards apex and both surfaces woolly.
Flowers
Broadly bell shaped, woolly flower heads appear singly or a few together, 1 centimetre (0.39 in) to 1.5 centimetres (0.59 in) in diameter.
Seeds and reproduction
Achenes .3 centimetres (0.12 in) to .5 centimetres (0.20 in); pappus 1.5 centimetres (0.59 in) long.[6]
Reports claim S. crassiflorus does not produce viable seeds and spreads itself asexually or via vegetative reproduction.[7][5]
