Pollination Information for Bartzella Itoh Peony (Paeonia x 'Bartzella')

Bartzella Itoh Peony is a hybrid cross between a tree peony and a herbaceous peony. It is a self-fertile plant, meaning it can pollinate itself and produce viable seeds. However, cross-pollination with another peony plant can result in interesting and unique hybrids.

Bartzella Itoh Peony is pollinated by insects, especially bees, who are attracted to its large, showy flowers. The plant typically blooms in late spring to early summer, and its flowers can last up to 6 weeks. During this time, bees will visit the flowers to collect nectar and pollen, inadvertently transferring pollen from flower to flower.

To encourage pollination and seed production, it is important to plant Bartzella Itoh Peony in a sunny location with well-draining soil. Adequate watering and fertilization will also help promote healthy growth and strong flowering. Deadheading spent flowers will redirect the plant’s energy towards producing new blooms and seeds.

If you want to experiment with hybridizing peonies, you can hand-pollinate Bartzella Itoh Peony by transferring pollen from one flower to another using a small brush or cotton swab. This can be done by gently dabbing the center of a recently-opened flower and then transferring the pollen to the center of another flower.

Planting & Care for Bartzella Itoh Peony

The Bartzella Itoh Peony is a hybrid variety that combines the best features of the tree and herbaceous peonies. It's an easy-to-grow plant that produces stunning yellow blooms in late spring to early summer. Below are some tips on planting and caring for your Bartzella Itoh Peony:

Planting

• Choose a planting site that receives at least 6 hours of full sun daily.
• Make sure the soil is well-draining and fertile. Add compost or aged manure if necessary.
• Dig a hole that is twice the width of the root ball and deep enough to accommodate the entire root system.
• Tease the roots gently to loosen them before planting.
• Place the plant in the hole and backfill with soil, making sure the crown of the plant is at soil level.
• Water thoroughly.
• Apply a layer of mulch around the plant to retain moisture and suppress weed growth.

Care

• Water regularly to keep the soil evenly moist but not waterlogged. Peonies don't like to be in soggy soil.
• Fertilize in early spring and again in early summer with a balanced, slow-release fertilizer. Avoid high-nitrogen fertilizers as they can promote leaf growth at the expense of flowers.
• Deadhead spent blooms to encourage more flowers and to prevent seed production, which can divert energy away from the plant.
• Support the plant with stakes or a peony ring to prevent the heavy blooms from drooping to the ground.
• Cut back the plant to the ground in fall after the foliage has turned brown. Dispose of the foliage to prevent disease from overwintering in the garden.
