If you want custom metal supports for your peonies, like the ones at NYBG, they are available from Bob Keating Metal Works.  You should be aware that the supports at NYBG are painted with a weather resistant black paint annually but they come from the metal worker with a natural steel finish. Some gardeners are worried when this finish begins to rust, but this phase is short-lived!  Keating recommends that if you are a home gardener you skip the annual maintenance and allow the supports to patina naturally.  They will quickly go from rusty to a uniform, dark, brown color that looks at home in the garden. 

The NYBG Shop in the Garden frequently carries the supports. You can call to see if they are in stock or if the shop can get them for you at  718 817-8869 or email them.
