No, it would be pure white - snow white. But with cut leaves like the
musk mallow - Malva moschata variant heterophylla. I'll sniff one next
time I see one and see if it is M. moschata.

I don't know whether it's indigenous, feral or a cultivated plant. It's
not anything I've ever seen in a seed catalogue or a nursery.

I once bought a packet of M moschata seed, and they were mixed, some
pink, some white. I encourage the white ones.
