Well, it's too late to take a picture now, I just got done pulling the weeds and vines manually yesterday.
By "parasites" I mean weeds and one of the worst reoccurring weeds is a choking vine which grows entwined with a few wild rose bushes I have. The other problem growths are crabgrass, very aggressively growing in my ornamental grassy plants (I have 25 of them, I don't know what they're called but they are low and green with white stripes) and what looks like bermuda grass growing in the same grassy plants as well as a few small and low bushes. Sorry, I don't know their names either.
All of my ornamental plants and shrubs are in beds covered with heavy duty weed block and 3/4" stone but that was done years ago and these parasites, as I call them, grew up in the hole that was there for the original ornamental plant or shrub.
I will try to remember to take a picture before I pull the weeds again.
