Allegheny Serviceberry
The Allegheny Serviceberry, Amelanchier laevis, is perfect for naturalistic plantings. This small, multi-stemmed, upright tree blooms in early spring with petite, slightly fragrant, white flower clusters. The purplish-blue fruit is delicious in pies and jams and very attractive to birds. This serviceberry is easily grown in average, medium, well-drained soil in full sun to part shade. It is tolerant of a somewhat wide range of soils, but prefers moist, well-drained loams. Allegheny Serviceberry makes an attractive understory tree for lawns, shrub borders, woodland margins or native plant areas. It has no serious insect or disease problems. ... additional info
Columnar Swedish Aspen The Columnar Swedish Aspen, Populus tremula 'Erecta', is native to the forests of Sweden. This slender tree is great for smaller spaces, screens and along drives. The dark green leaves have a lighter silvery-green underside providing both visual interest and a soothing sound in the breeze and tremble with the faintest whisper of wind, creating the same pleasant rustling sounds as the leaves of Quaking Aspen. It is well adapted to very cold climates, but needs adequate moisture. This tree is an excellent substitute for a Lombardy Poplar in cooler climates. It is best suited for small yards, as a screen or a vertical accent. It has none invasive root systems and cottonless. The fall color can range from orange to red. Somewhat adapted for street and boulevard planting, the Columnar Swedish Aspen will provide both visual interest and a soothing sound to the landscape.
