thanks for your comment vonvonz :)
the #2 one is exactly like what you said (after checking the link that you gave me)... it's called
Orthosiphon aristatus 'Purple' ( Purple Cat's Whiskers )
geez... sounds like alien's language to me :D
How about using a cloning tool to CLEAN the dirt.... then using Unsharp Mask to make the object (currently blur?) a bit sharp ?.... however, it's always best to re-take the picture again :)
