Peony 'Bartzella Itoh' (Intersectional Peony)

'Bartzella' is a landmark Itoh (intersectional) peony, a hybrid between tree and herbaceous peonies. It produces very large, semi-double to double, bright lemon-yellow flowers (6–8 inches) with a subtle spicy fragrance. The sturdy stems require no staking, holding the blooms above lush, deeply dissected, dark green foliage. An exceptionally vigorous plant, it forms a substantial clump 3–4 feet tall and wide. Herbaceous perennial; dies back in winter.
