Thank you all for your thoughts....I'm kind of interested in interspersing them with a vertical element--like Karl Foerster (sp?) grass, which is my favorite grass and also...my dogs' favorite grass. They dart straight to my patches here and there. I use the KF grass in a similar situation as I'm thinking about with the cotoneaster--with Siberian cypress, so like a low arching plant surrounding a strongly vertical element (on a small scale, like the oak mentioned above). I'm thinking, if the grass is surrounded by the cotoneaster, the dogs can't get to it, and it will have nice fall/winter interest.
It's so weird--I buy lots of ornamental grasses and it's a big rural property with grasses galore, but jeezum crow do the dogs like the KF grass. They ate it so much it disappeared from one of my gardens. They dart directly to it . Now I have to figure out how to protect the remaining patches.
I'm glad people like them...they're heeled in the vegetable garden and I like their fountain-like growth pattern.
Throwing them between the currants is just my 'if I throw my hands up' idea. At least it will combat the poison ivy.
