American Wisteria `Amethyst Falls`
American Wisteria ‘Amethyst Falls’ (Wisteria frutescens) 10-25’ x 4-8’ fast-growing twining vine, or can be trained into a small tree or standard. Not an aggressive spreader like Asiatic Wisteria, as it doesn’t send out long root suckers. Native to SE U.S., found in alluvial forests, moist-wet thickets, margins of damp woods, riverbanks, swamps. Abundant showy 4-6” dense drooping clusters of ¾” fragrant pea-like bluelavender flowers with a yellow spot, held above leaves on 3” stems. Begins blooming April, after leaf-out, continuing in waves over a few weeks, then sporadically during the summer, on current season’s growth. 7-12” shiny pinnately-compound leaves, with 5-6 pairs of slightly drooping gray-green 2” leaflets with soft green undersides. 2-4” brown bean-like smooth pods ripen in summer, and split open in fall. Reddish brown twigs age to warm gray, handsome in winter. Because the plant develops a thick coiled trunk, provide a sturdy support. Sun to part sun. Prefers moist fertile well-drained soil. Tolerates moderate drought and seasonal flooding. Superphosphate fertilizer in early spring can help stimulate flowering – probably does not require nitrogen, which encourages only foliage growth. Aside from light shaping after blooming, and some thinning in winter (or severe pruning if size reduction is sought), the plant requires little care. Does not like being moved. Highly deer resistant. Excellent vine for strong trellises, arbors, pergolas, fences, columns, walls, or trained as small tree; in cottage, formal, or small gardens. Attracts bees, butterflies, and skippers. Larval food for Silver Spotted Skipper, nectar for Juvenal’s Duskywing.

A Weston Nursery (Massachusetts) 1963 cross of Rhod. arborescens (Sweet Azalea), native from New York south, found on stream banks and moist wooded slopes, and Rhod. cumberlandense (Cumberland Azalea), from the Appalanchians. Both are found in moist acidic soils. Extremely fragrant pink flowers with a yellow flare, blooming in mid June, becoming silvery pink by late June. Medium to dark leaves, red-orange in fall. Prefers part shade, in moist to damp fertile humusrich acidic soil. Because the roots are clustered toward the soil surface, give a mulch covering. Mildew resistant. “Proven Performer” of MA chapter, American Rhododendron Society. Use in woodland gardens, at edges of wooded areas, in naturalized settings, in streamside areas, or where you can appreciate the fragrance of the flowers. Attracts butterflies, hummingbirds. Larval food for Striped Hairstreak and Brown Elfin, nectar for Skippers and Swallowtails. Photos 1, 2 American Rhododendron Society Massachusetts Chapter Website photos by Sally and John Perkins Photo 3 Weston Nurseries www.westonnurseries.com Flame Azalea (Rhododendron calendulaceum) 4-8’, narrow base, tall arching stems. Native Pennsylvania south, found in moist woods, slopes, by stream bank. Flower buds resemble candle flames; trusses of brilliant lemon, apricot, and scarlet 2” flowers, May-June. 3-4” leaves; yellow to red in fall. Sun to part shade, high dappled shade best; moist to average acidic humus-rich soil. Excellent in masses, open woods, shrub borders, for striking blooms. Habitat for songbirds, hummingbirds, butterflies, small mammals. Streamside buffers. John Bartram, the pioneer 18th century American horticulturist, described Flame Azalea: "Clusters of blossoms cover the shrubs in such incredible profusion of the hillsides that suddenly opening to view from dark shades, we are alarmed with the apprehension of the hill being set on fire."
