Sonoma Halo Itoh Peony

You'll fall hard for its yellow, fully double flowers, which open on sturdy stems and reach 5½" in diameter. The plentiful, slightly ruffled petals fade to creamy white along the outer edges. Pink flares are present but not prominent, due to the fullness of the show-quality flowers. This hybrid has a spreading habit but does not require staking. Sonoma Halo is an Itoh peony, a cross between a tree peony and a bush peony.
