H!  The local park here has a bunch of plants that I suspect are black currant bushes but want to make a positive ID as I don't know if there are poisonous plants out there that look like them.  They look like currants to me, and in the summer when the plants are covered in these berries and theyare ripe, they are black and glossy.  In addition, the leaves are very fragrant....maybe odoriferous is a better word.  They smell.  A lot!

Are these plants black currants?
