This picture was taken last summer after I did the very front garden bed. The back of the bed has crotons and the front has gold mound durantas mainly. I am trying to make it more interesting so thinking of adding some height with a hawaiian ti's.

The part I really want to change up is by the walkway to the front door where the lillies are currently that space is 4ft by 16ft long. I was thinking hawaiian ti flanking the large 72" window with some kind of a shrub in the front to hide the stems if the Ti's. Have that same shrub thats in front of the Ti curve back under the large window with something in front of it and then back in front of the Ti's on the other side of the window. It's full shade faces north. Any help would be appreciated!!
