I know this may be hard to identify since I don't have a picture..

I was at a friend's house the other day and his mother has a very large, really pretty, shade garden...I noticed several Adam's Needles (with large/tall blooms)...hostas..vines...lemon mint..chameleon plant..and a lot of other things I didnt know ..in the very back of the garden is green grass that is well over 6 foot tall. It grows up then sort of falls forward.. I don't know whether it's called fountain grass or ornamental grass or pampas grass ( I don't know the difference in grasses) ...most of the grass seemed simply green..but there was one section that had yellow splotches up and down the blades...she said she mows it down every spring and it grows huge the rest of the season..

She said I was welcome to come take whatever I wanted out of that garden.

What I don't know is if there is a certain time of year you can dig the grass up and replant it and I don't know what to properly call it so that I don't sound so "new" lol..

As for the Adam's Needle, I know it isn't grass, but are they split like you would split a hosta?

Just curious to see if you all could answer the question.

Thanks!
