Even the biggest, heaviest blooms like peonies can hold their heads high with the help of these flower supports. Set them out in spring and stems will grow right up through the supports, keeping plants standing straight and tall and preventing unsightly flopping. The concentric rings forming the top of the support hold stems in more natural form than grid-shaped supports. Set of three supports; each support consists of one top and three legs. The 12" support is ideal for short to medium-height flowers, including compact varieties of coreopsis, zinnia, campanula and veronica. The 18" support is perfect for shrubby flowers like taller zinnias, salvia, young peonies, Shasta daisies and poppies. The 24" support holds larger plants, like mature peonies, campanula and rudbeckia.
