Paeonia ITOH ‘Bartzella’: The Exceptional Yellow Peony, Combining Strength and Delicacy

The Paeonia ITOH ‘Bartzella’ is an exceptional hybrid peony, a cross between a herbaceous peony and a tree peony. Renowned worldwide for its immense, slightly fragrant lemon-yellow flowers with golden centers, it combines vigor, floriferousness, and rare elegance. A true garden jewel, it brightens flowerbeds from May to June, bringing the radiance of the sun to spring landscapes.

Spectacular and Refined Blooming

‘Bartzella’ forms a rounded, robust, and well-structured clump, reaching 80 to 100 cm in height and about 90 to 100 cm in width. Its semi-double to double flowers, 15 to 20 cm in diameter, open in a luminous yellow, sometimes with orange or red nuances in the center. Each flower emits a light citrus scent, adding a touch of freshness and sensuality. Thanks to its sturdy stems, it does not droop under the weight of the flowers, making it a highly sought-after variety by enthusiasts.

Cultivation and Care

Paeonia ITOH ‘Bartzella’ thrives in full sun or light partial shade, in deep, fertile, humus-rich, and well-drained soil. It appreciates cool ground without excessive moisture. Very hardy (down to -25 °C), it establishes itself permanently and develops slowly over the years. Plant it in autumn or spring, being careful not to bury the main bud more than 3 to 4 cm deep.
Low-maintenance, it simply requires cleaning faded stems in winter and light fertilization in spring.
