Paeonia suffruticosa--Tree Peony, Moutan Peony


Hardiness Zones: 3 to 8
Height: 5 ft Spread: 4 ft
Type: herbaceous perennial
Flowers: Pink, red, white, yellow, purple

Comments: Tree Peony is shrub-like as it reaches a height
of 3 to 5 feet (Vis. 1). The plant grows slowly but the
large, 10-inch flowers (Vis. 2) are worth the wait. The
plants grow in ordinary garden soil with exposure to sun or
partial shade. The flowers may be single or double and are
produced in May or June. Plant the graft union 3 to 6
inches below soil level to encourage the scion to develop
roots. Remove dead stems as they are seen.

Propagation: Propagation is by grafting, air layering or
division. The first two methods are difficult, slow, and
uncertain for most gardeners. Division can only be done
to large plants with many branches on which the scion
formed roots.
