These are heavy duty plant supports that, used alone or in groups, can handle large peonies, big floppy geraniums and a row of catmint! They are curved deeply enough so 2 together makes a 12” diameter support, and 3 together make a 21“ diameter support. You can even place 3 and link them with twine, making these perfect for large perennial clumps that grow into odd shapes! The stakes are of a 5/16'‘ steel, beautiful and strong! Of course, American made to last! As with all the steel supports, they will age to a rust patina.
