Look-alike warning

Could be mistaken for Other plants with a similar name or look. To tell them apart: Match on the scientific name, Senna artemisioides (Gaudich. ex DC.) Randell (Kew WCVP accepted; VicFlora accepted; the SA planting guide prints it as "Senna artemisoides"), not on the common name.. VicFlora says Senna artemisioides is a complex of 15 subspecies whose features vary widely and often intergrade. Our source (Botanic Gardens of SA) covers subspecies artemisioides only, so its size and flower figures may not match other subspecies. Check the subspecies when buying.

Poison control
