If you continue along the end of the path, we start heading toward the new "Sitting Deck" which you'll see soon. The trees and shrubs were planted in 2007 and in late 2008 these plants were added to the left of the combination you saw before.
From the top right: Pheasant Berry (Leycesteria formosana 'Golden Lanterns'), Variegated Adam's Needle (Yucca filamentosa ssp. smalliana 'Bright Edge'), more Pineapple Lily with Gold Stonecrop (Sedum rupestre 'Angelina'), Blue Beaked Yucca (Yucca rostrata 'Sapphire Skies'), Cushion Spurge (Euphorbia polychroma 'Bonfire'), European Hornbeam (Carpinus betulus 'Fastigiata'), Copper Leaf Ninebark (Physocarpus 'Coppertina'), and at the top of the photo - the blue foliage of White Willow (Salix alba f. argentea).
