Peony & Herbaceous Perennial Frame Make gardening easy and take the hassle out of staking herbaceous peonies and other perennials with this super sturdy support frame. As lovely as Peony flowers are, they are rather large and grow heavy showy blooms which sometimes need some extra support! Simply position this frame around the crown of the plant in spring. It will support the stems as they grow, and keep your flowers facing upwards when summer comes. Height: 45cm. Width: 35cm.
