Remarks oj Special Interest 



Good for borders, preferring moist soil. Flowers red-tinged to white. Clusters of red 



fruit make attractive showing. 5. melanocarpa (nigra) a lower form, with black berries. 

 Rich purple flowers early and in profusion. Hardy usually around New York. Several 



forms and crosses showing various shades of red and purple. 

 The earliest-flowering species, usually before the end of April. S. vulgaris and 5. 



Chinensis follow quickly, including many colors from white to purple. 

 Bright yellow wood. Handsome foliage becoming golden in autumn. Flowers small, 



dark, in loose, hanging lashes. Prefers moist, shady situation. Often not hardy. 



Includes many varieties, all hybrids, some of undetermined parentage. These embrace 



all shades of white, yellow, pink, red and lilac. Flowering May to July. 

 Red-branched, profusely flowered species. There is a yellow-barked var. C. candidissima 



is later and smaller, with gray branches, free flowering. Grow in most soils. 

 The most decorative hardy cotoneaster; bears red fruit. C. buxijolia, a low, evergrc-6n 



species with especially attractive red berries. Needs well-drained soil and sun. 

 Very beautiful when covered with snowy blossoms. D. Lemoinei more spreading and 



more hardy in New York. Well-suited for shrubbery borders in well-drained soil. 

 Naturally is irregular and bushy, but may be trained to tree form. Flowers like snow- 

 drops before leaves. Easily transplanted from woods and grows well in shelter. 

 Needs treatment like rhododendrons, but is less particular as to soil. Transplant in 



early fall, and mulch the first winter. Provide shade if moisture is lacking. 

 Dark green foliage sets off the many white, changing to yellow flowers, and the bright 



red fruit from August until winter. Another var. with yellow berries. 

 The common, reliable form, including varieties of different colors, some double. The 



hybrids P. Zegheri and Lemoinei are lower, more spreading, more effective. 

 Flowers small but abundant. Purple decorative fruit edible. Grows vigorously anywhere 



not too wet. Well suited to sandy soil. Often attacked by black knot. 

 Hardy in Massachusetts, with some protection. Red fruit in profusion usually last 



all winter. Grows well in most soils; prefers a sunny position. Is easily trained. 

 Conspicuous for its large white flowers and bright green foliage. Shiny black fruit 



usually persists over winter. Will do well in almost any good soil. 

 A thorny, hardy, very ornamental shrub. Large white flowers, dark foliage persist- 

 ing late, and large orange-colored fruits all winter. One of the best roses. 

 The most effective early spirea. Other valuable species are S. Thunbergii, Cantoniensis, 



Van Hoiillei, bracteata and prunijolia. All these do well in moderately moist soil. 

 Hardy. Gradually replacing V. Opultts, var. sterile, the common snowball often infested 



by aphids. V . macrocephalum, var. sterile, huge flower clusters. 

 Resembles mountain ash. Showy terminal flower clusters and decorative foliage. Will 



grow in most any soil; hardy when established. Comparatively free from insects. 

 Hardy, vigorous. Drooping tassels of yellow replaced in fall by red berries, persis- 

 tent over winter. Will thrive almost anywhere. Good for single or mass planting 

 Handsome pea-like flowers. C. arborescens, much larger, and C. microphylla, C. ham- 



lagu, and pygmcea dwarfs. Hardy and grow best in a sandy, sunny location. 

 Recommended for covering raw and broken bits of landscape. Fairly hardy north, 



but if winter killed will grow new branches. Flowers appear along nearly bare stems, 

 Especially handsome with its purple fall foliage. E. obovalus a low-trailing species. 



and E. radicans a climbing evergreen. Easily grown in almost any soil. 

 Silvery foliage and orange-colored berries very effective. Will stand sandy soil. Excel- 

 lent for seashore planting. To obtain fruit effects mix forms in planting. 

 Give plenty of space for spreading and to show the drooping terminal clusters. Does 



well in sun or shade in ordinary soil. Comparatively free from pests. 

 The most decorative of the currants. Dark blue or black fruit. R. alpinum has red 



berries. Both species hardy and vigorous everywhere. Free from thorns. 

 Flowers many but small. Especially valuable for its silvery foliage and yellow, edible 



berries. Plant in prominent positions. S. Canadensis may do better. 

 A shrub in culture, by nature a tree. The most beautiful species, but less hardy than 



C. Canadensis, a larger form. Transplant when young in rich, sandy loam. 

 Very free-flowering, showy and rather hardy. Varieties range in color from a white to 



deep rose. Thrives in warm garden soil, shade and moisture being most desirable. 

 An early species, but as hardy as Catawbiensc. Blossoms pink to rosy purple. Needs 



good soil and some shelter without shading. Excellent around large, high trees. 

 Blooms into June and often during summer. Good for banks or isolated masses, 



where its spreading habit will not affect other plants. Injured by borers. 

 A pink medium early species. The culture for ail the lilacs is the same. Cut off dead 



blossoms and prune them to give time for next year's flowering wood to grow.
