Scientific Name (Genus/Species): Kirengeshoma palmata Koreana Group (syn. Kirengeshoma koreana)

Family: (Hydrangeaceae)

 

(P) to 4′.  A Korean dignitary.  Large, sharply lobed, maple-like leaves in opposite pairs display a handsome silvery pubescence when emerging in spring.  The foliage provides interest through late summer when the flowers emerge.  Pale yellow, waxy, five-petalled flowers are borne on a stiffly upright inflorescence.  Blooms a bit earlier than K. palmata.   A “must-have.”  Prefers partial shade.  5 & T2

Scientific Name (Genus/Species): Aralia continentalis

Family: (Araliaceae)

(P) to 4′. Manchurian Spikenard. Clump-forming, architectural perennial with arching stems of alternate, bipinnate leaves. In midsummer, many terminal racemes of green flowers are soon followed by globose, blue-black fruit. Partial shade. Likes moisture. 3 & 7 for 4 months, then T1

Scientific Name (Genus/Species): Campanula hofmannii (syn. Symphyandra hofmannii)

Family: (Campanulaceae)

(P) to 2′. A Bosnian native. Marvellous, creamy white, pendulous bells in terminal racemes contrast with the serrated basal leaves. Showy seedpods, too. Self-sows gently. Sun/partial shade. 4 & T2

Scientific Name (Genus/Species): Actaea japonica (syn. Cimicifuga japonica)

Family: (Ranunculaceae)

(P) to 3′. Bugbane, Rattletop, Snakeroot. Numerous creamy, tufted, sessile flowers bloom on spikes from August through October. Shiny lobed and toothed leaves are very attractive in the woodland. Self-sows nicely. Partial shade. 3 & 6A

Scientific Name (Genus/Species): Actaea simplex 'Brunette' (syn. Cimicifuga ramosa 'Brunette')

Family: (Ranunculaceae)

(P) to 6′. One of the darkest leaved Cimicifugas. Stems are a rich purplish brown with pure white, upright, fragrant flower spikes in September. Not all seedlings will be as dark as ‘Brunette’, but definitely worth a try. Partial shade. 3 & 6A

Scientific Name (Genus/Species): Anemone virginiana

Family: (Ranunculaceae)

(P) to 2.5′. Central and eastern United States. This plant has long petioled, toothed basal leaves. The flowers are greenish white and not long lasting. However, the fuzzy, white, cotton ball-like seedheads provide an interesting addition to the garden throughout the summer. Not fussy. Partial shade. 3 & 6 & T2

Scientific Name (Genus/Species): Aruncus dioicus

Family: (Rosaceae)

(P) to 5′. Goat’s Beard. Europe and Russia. The tall stature and presence of this Aruncus with its large, creamy white, feathery plumes makes it a show stopper for the back of the border. Prefers moist soil and partial shade. Early summer bloomer. 4 & T1

Scientific Name (Genus/Species): Astilbe biternata

Family: (Saxifragaceae)

(P) to 4.5′. False Goat’s Beard. North America. The only native Astilbe and unaccountably rarely seen. Tall, imposing stems with profuse, creamy white flower panicles light up the woodland in early summer. Dark green foliage is lush and resembles Actaea. Partial shade. 4 & T1

Scientific Name (Genus/Species): Astrantia major

Family: (Apiaceae)

(P) to 2.5′. Great Masterwort. Central and eastern Europe. No garden should be without this effortless and beautiful plant. Several greenish white, often blushed pink flowerheads each arranged in a dome with a “collar” of bracts. Dense clumps of divided basal foliage. Content in the flower garden or in the woodland. Summer blooming. Great in flower arrangements, too. Sun/partial shade. PC- 4 weeks. 4 & 7 for 4 weeks, then T2

Scientific Name (Genus/Species): Darmera peltata

Family: (Saxifragaceae)

(P) to 4′. Umbrella Plant. Northern California and Oregon. Broad clusters of pale pink flowers appear in spring before the foliage fully emerges. Astonishing clumps of large, rounded, scalloped leaves on thick, hairy stems. A grand effect for a pond or bog garden; combines well with other moisture lovers such as Primulas and Ligularias. Blooms April to July. Moist to damp soil. Shade/partial shade. 4 & 7 for 4 weeks, then T1
