This plant has many thorns and spines on it so you can't really pick these off with your hands.It's are kinda the same,the stems are cover in spines and looked kinds fuzzy.

They have these tear shaped buds green and sharp and once they blow they turn in to these beautiful little purple flowers like in the picture.

when they wilt the purple flowers turn white and soft but still sharp and give off little seeds.the seeds look like dandelions seeds.

When this plant disperse it's seeds it's kinda like dandelions when they disperse there seeds. Theirs a picture of one the seeds in one of the links above.

I saw this plant in a place where it gets it's sunlight mostly in the afternoon when the sun is in the east.I don't know about how much water it needs though,it looked in good condition so i think got a good amount of water.

kind think its a weed. so if some one could help me please i would really appreciate. and if you need more picture s have some more and thanks you
