Weed or flower?



This is my second attempt at this post.Blogger crashed last time.I was asked about the Oxalis bulbs which i planted.In California (Alameda) the oxalis are a noxious weed.I wandered if what i planted was the same.Some internet research later and i have some answers.
The first pic is Oxalis Deppei, also called woodsorrell, four leaf clover , or iron cross.It has pink flowers and is sold near St Patricks day.
The second was the Alameda/California villain Oxalis Pes-Caprae.The Bermuda buttercup.It is invasive by its free forming bulbs and side roots like icycles.It crowds out other plants and stops them growing.
Check out this American article: http://cnps-yerbabuena.org/hab_sigg_oxalis.html

Wilkopedia have this about Oxalis: http://en.wikipedia.org/wiki/Oxalis

Its a gree word for acid because of the bitter taste of the plant.Oxalic acid was used before as a folk remedy but too much is poisonous.
What interested me is the common name is Oxalis but with 800 species thats a lot of confusion about which is a weed and which is a flower.
I will photgraph them when they start to bloom.The bulbs have already sent up the seedlings in my front window border.

Thanks for the photos and the research. The Oxalis Deppei is quite pretty! But the second photo--that seemingly innocent yellow flower--haunts me in my dreams.
