Plant Profile: Paeonia suffruticosa

The Tree Peony, contrary to what its name suggests, is a tall, upright deciduous shrub with coarse branches, reaching heights of up to 6.5 feet. This impressive plant typically flowers from mid to late spring, producing a remarkable display. However, excessive shade or competition from nearby tree roots can hinder its blooming potential. The stems of the Tree Peony are fragile, necessitating staking or protection from strong winds. A single plant can yield between 75 to 100 flowers throughout its two-month blooming season. It is worth noting that this species is not particularly resilient in the southern extremes of its hardiness range (zones 4-7). The Tree Peony can tolerate partial shade, alkaline soils, heat, and browsing by deer and rabbits, but it thrives best in moist, well-drained, and nutrient-rich soils. It is sensitive to drought and may face issues with pests and diseases. When pruning, it is important to only trim for shaping purposes and avoid cutting it back to the ground like other peony varieties after flowering.

Regarding pests and diseases, while ants are often spotted on peonies, they pose no threat. However, the plant can occasionally suffer from canker, leaf blight, and stem wilt.
