ITOH Peony

A must have in the garden

Itoh Peony is also known as an Intersectional Hybrid.  This plant is a cross between a traditional garden peony and a woody tree peony, taking the best attributes of both plants.  It has up to 50 enormous sized flowers once established.  This hybrid is a relatively creation with the first successful cross made in 1948 by the Japanese breeder Mr.Tiochi Itoh.

Planting & Care Instructions

Itoh Peony is easy to grow in moist, well-drained soil.  Work the soil around the planting area to allow for a deep and extensive root system to develop.  Place the plant in the ground, keeping the plant even with the soil line.  Once in the ground keep the soil moist but take care not to over water.  Provide an extra helping of fertilizer that is low in Nitrogen like Espoma Plantone while the plant is in bloom.  Also remove spent flowers to encourage a fresh burst of color.  In the fall, cut the Itoh back to 4-6 inches up from the soil level.
