Paeonia × suffruticosa 'Joseph Rock'

[Joseph Rock Tree Peony]

The Tree Peony is a long-lived, very showy, deciduous shrub that produces numerous large, beautiful flowers beginning in mid to late spring. 'Joseph Rock' has large, semi-double blossoms with white petals that each have a dark purple flare at the base. These plants do best in a deep, fertile, and well-drained soil, with some protection from strong winds. In colder climates, some winter protection is beneficial to prevent desiccation. The only pruning necessary is to…

Paeonia × suffruticosa 'Renkaku'

[Renkaku Tree Peony]

The Tree Peony is a long-lived, very showy, deciduous shrub that produces numerous large, beautiful flowers beginning in mid to late spring. 'Renkaku' has large, white, semi-double blossoms. These plants do best in a deep, fertile, and well-drained soil, with some protection from strong winds. In colder climates, some winter protection is beneficial to prevent desiccation. The only pruning necessary is to remove dead wood and suckers in early spring, or a light pruning in…

Panicum virgatum 'Thundercloud'

[Thundercloud Switch Grass]

This tall hedge grass can grow up to 8 feet tall, making it a great option to buffer views or frame spaces. Open panicles frame the crown creating a soft fluffy top that contrast the dark green switchgrass blades.

Parrotia persica

[Persian Parrotia]

One of the best trees for foliage and bark effect. Very adaptable, tolerating drought, various soils, heat, cold, etc. Prefers full sun but tolerates light shade. Sites with strong winter winds will surely cause tip dieback in Northern Indiana.

Parrotia persica 'JLColumnar'

[Persian Spire™ Parrotia]

Parrotia persica 'Vanessa'

[Vanessa Persian Parrotia]

Vanessa is a cultivar that has a distinctly upright or columnar habit. One of the best trees for foliage and bark effect. Very adaptable, tolerating drought, various soils, heat, cold, etc. Prefers full sun but tolerates light shade. Sites with strong winter winds will surely cause tip dieback in Northern Indiana.

Parthenocissus quinquefolia

[Virginia Creeper]

One of the strongest-climbing vines, given solid support for attachment of the adhesive discs on tendrils (not root). Not a vine for trellises or fences. Tolerates any soil, and sun or shade. Limited value as groundcover.

Parthenocissus tricuspidata

[Boston Ivy]

One of the strongest-climbing vines, give solid support for attachment of the adhesive discs on tendrils. Not a vine for trellises or fences. Very tolerant of urban soils. Not a good groundcover.

Passiflora caerulea

[Blue Passionflower]

This is one of the hardiest passion flowers, dying back in colder climates, but hardy to 10 degrees F. (It is suspected that the specimen at Purdue University in West Lafayette, IN (USDA zone 5a), is kept alive in the winter by the heat radiated from the greenhouses and building it is planted near.) Plant is evergreen in tropical environments. Extraordinary flowers and tasty, edible fruits (passion fruit). Prefers loose sandy or gravelly soil that…

Phellodendron amurense

[Amur Corktree]

A striking tree for its interesting bark and massive framework. Widely adaptable to soil, trouble-free, and drought and pollution resistance. Easily transplanted. May be less hardy when young and rapidly growing. Fruits smell like turpentine when crushed (or stepped on). This tree is demonstrating invasive characteristics in suburban and urban fringe forests. It escapes intended plantings to invade and displace native hardwood forests. Note: only female plants have the potential to become invasive. Phellodendron amurense…
