looks like it to me Cammomile.

they make nice house plants. but if you have cats they can cause mouth irritation if they chew the leaves as my daughter found out.

Thanks Sbg. No they live in an apartment, no pets allowed and I don't think they like plants either. Its winter over there so maybe she's been a bit generous with watering.

it might also want a light feeding. Mine tends to yellow in the winter and a weak tomato feed perks it up. mind you I need to repot it soon as its been in the same pot for 3 yrs now.

It might need feeding, but if it's only one or two yellow leaves, those may just be old leaves. Regular, moderate feeding is usually a good idea with container plants anyway, because the roots can't spread out looking for dead bugs, mouse bones, feathers, etc.

The yellow leaf seems to be at the bottom so maybe it's an old one. Mine go like that and I cut them off. The rest of the leaves look all right. If it had been over watered I think all the leaves would be affected.

Thanks everyone, I shall pass your answers on.
