Pieris japonica 'Flaming Silver' The other two near the Kerria are Pieris - I wasn't certain. Not sure which cultivars you have, but it looked like they were happy were they were. Not suggesting you move them, just thought you might want the name.
Money Plant - Biennial. Grown for the silvery white, flattened, disc-like seed pods. Attractive in dried arrangements. Plants bloom with clusters of lavender flowers in spring and make pods second summer after seeds are sown.
Sea Holly Alpinum (Eryngium Alpinum Superbum) - Eryngium Alpinum Superbum is nothing short of fantastic and is easy to grow from Eryngium seeds. It is commonly known as Alpine Sea Holly, and it is one of the showiest Sea Holly plants available on the market. The metallic stems and large thistle-like flowers mature to an intense steel blue color from summer through fall.
