Common Name: Scentless Mayweed (Mayweed, False Chamomile)
Latin Name:Matricaria perforata; Tripleurospermum inodorum
Family Name: Asteraceae/Compositae
There is little data on Scentless Mayweed, but because it is closely related to the Scented Mayweed, it could potentially contain the chemical compound coumarin, which soaks up nitrogen in the form of nitrates from the soil and is also used to manufacture anticoagulant drugs. Although a little will not harm your tortoise, it shouldn't be offered on a regular basis.
The flowers and form of the Scented Mayweed, Scentless Mayweed, and Stinking Mayweed are similar. The flowers of all three are daisy like, have white petals with yellow centres. It can therefore be difficult to identify these plants with confidence.
Scentless Mayweed (as the name suggests) has no aroma if the leaves are crushed.
