Scientific Name (Genus/Species): Pulsatilla patens
Family: (Ranunculaceae)
(P) to 12″. Eastern Pasque Flower. Native to Europe, Russian, China, Canada and US. Blooming in April at 4″ high, before the leaves develop, the ethereal, open, bell-shaped, flowers command attention. The solitary, two-inch flower has six blue-violet, petal-like sepals and a ring of many yellow staminodes that surround a light green central boss of stamens. The sepals are pointed at the tip and lined with many parallel veins. Flowers, stems and foliage are all covered in fine, silky, whitish hairs. The flowers are followed by plume-like seed heads (reminiscent of some Clematis and Geum) that have good ornamental interest. Deeply divided basal foliage grows to 12 inches tall after the flowers have faded. A great rock garden plant and the state flower of South Dakota. Grows best in drier, sandier soil. Sun. 3 & T2 & ∆

Scientific Name (Genus/Species): Mirabilis longiflora
Family: (Nyctaginaceae)
(TP) to 3.5′. Sweet Four o’Clock, Angel’s Trumpets. Texas, Arizona and Mexico. Extraordinary, six-inch long, very slender, white trumpets are borne in great profusion on mounds of sticky, bright apple-green foliage. The flowers release a sweet orange-blossom fragrance in the evening. These unusually long flowers need a special pollinator with an extended proboscis, such as the Hawkmoth. The Hawkmoth is similar to the Hummingbird in that they hover in place and unfurl their proboscis and drink the sucrose-rich nectar they require, thus creating a mutually beneficial relationship. Lift and store the swollen tubers over winter as you would a Dahlia. Blooms midsummer to fall. Sun/partial shade. 4 & T3

Scientific Name (Genus/Species): Schisandra chinensis
Family: (Schisandraceae)
Vine to 29′. Five Flavour Berry. Not only an attractive, hardy and unusual vine for a trellis or pergola but an intriguing plant with a rich history in Chinese herbology. The common name speaks to the fact that the berries possess the five basic flavours – salty, sweet, sour, pungent (spicy), and bitter. It is used widely in China and Russia to produce juices, extracts, wine and sweets and is considered one of the 50 fundamental herbs in Chinese herbalism. The deciduous leaves are a deep, glossy green, elliptic to ovate, and up to 5-½ inches long. Leaf margins are somewhat variable and described as cuneate, denticulate or serrate. Wonderfully fragrant, half inch, pale rose to bright pink flowers occur in axillary clusters on pendulous one-inch long pedicels. Small, scarlet-red fruits borne in dense, hanging clusters to four inches long, ripen in autumn. Berries, leaves and bark have a lemon-like aroma. Plants are dioecious, requiring male and female plants present in order for seed to develop. Blooms late spring and early summer. Sun to partial shade, moist, humus-rich, but well-drained soil. 2, 3 & 6A
