this rare and rosette forming weed-like plant has azaming white spotting across its leaves which also are prickly to touch with spine on the edges like a thistle. Anyone can give more insight?
I agree, Silybum marianum. It can be quite attractive when young if the foliage rosettes are perfect, but eventually it will grow into this http://www.botanicalstockphotos.com/img10887.htm , which is something you probably don't want.
