*The typical leaf formation of a gansu tree peony
When selecting tree peonies it is important to think of the presentation of the plant when not in flower. That will relate to the height (dwarf, medium, tall), the growth habit (conical, partially spreading, spreading), and the leaf type.
Typically height and growth habit are closely associated. Most dwarf varieties will be spreading, have leaf coverage that spreads to the ground, and become wider than they are tall. Medium height tree peonies are typically partially spreading, forming plants that are as wide as they are tall (5' in diameter and 5' tall). Tall tree peonies are typically conical and form bushes that are taller than they are wide, growing more vertically than they do horizontally.
Dwarf plants are ideal in the front of the garden as they will become densely leafed button bushes. Mid height tree peonies make excellent stand alone plants. They are often seen in a corner that is partially protected from wind, with ample space around them. The coverage at the base is typically sufficient to make the bush beautiful on its own. However they make excellent accent plants at the back of the garden. Tall plants should be planted behind other plants as they have minimal leaf coverage toward the base and will grow rather tall, up to 7'. Plan for ample space in the garden for them to grow into. Keep in mind that tree peonies are slow growing plants and will take 10-15 years to reach maturity.
The leaf type varies widely among tree peonies. Gansu tree peonies are aptly named as they come from the gansu region of China. Plants from this region have a thin, billowy leaf that is our favorite leaf type in the garden. These plants grow quickly and provide excellent greenery and beautiful flowers.
