Panicum virgatum

(Switch Grass) Plant in full sun in moist, fertile soil (although this plant will adapt to a wide range of soil conditions). Space plants 20-40" apart. Excellent spreading perennial, growing 4-5' tall with flowers blooming in fall. Ideal for the back of the perennial border. Hardy in zones 4-9.

Papaver Orientale

(Oriental Poppy) Plant in deep, rich, fertile, very well-drained soil in full sun to partial shade. It is especially important that the soil is not water-logged in winter; that spells death to the roots. Space 24-36" apart. Once planted, do not disturb. The long taproots can easily break. Intolerant of hot humid conditions; thrives in areas with cool summers. For best effect, plant in groups of no more than three. Foliage dies back soon after plant flowers. Grows 30-36" tall. Blooms May-June. Hardy in zones 3a

Pardancanda norisii

(Candy Lily) Plant in full sun in ordinary garden soil. Plant roots about 1" below soil level. Space 12" apart. Grows 36" tall. Blooms summer; seed heads of interest in summer and fall. Hardy in zones 5-8.

Pasque Flower

See Pulsatilla vulgaris

Pennisetum

(Fountain Grass) Plant in moist, welldrained soil in full sun to light shade. Will grow in almost any soil, except those that are poorly drained. Space plants 24-36" apart. Flowers bloom in summer, with seedheads that remain well into the winter months. Develop into mounds approximately 30-36" tall. Hardy in zones 5-9.

Penstemon Digitalis

Prefers full sun to partial shade and fairly rich, light, free-draining soil. Benefits from the addition of masona

Penstemon glaber

Plant in spring or fall in full sun in well-drained soil. It is important that the soil is well-drained, otherwise it will rot. Space plants 36-48" apart. Grows 48-60" tall and just as wide. Blooms June to first fall frost. Hardy in zones 5-9.
