Serviceberry Amelanchier × grandiflora 'Robin Hill'
ABOUT
The 'Robin Hill' serviceberry is an ornamental plant known for its stunning display of flowers and foliage as it progresses through the seasons. In spring, it is adorned with an abundance of soft pink flowers that gradually turn white as they mature. These flowers are arranged in pretty clusters that create a delicate and airy appearance, adding a touch of elegance to any garden setting. As the plant moves into the summer, the flowers then give way to small, round berries. Initially, these berries are a deep red color and are quite attractive in their own right. As summer progresses, they transform into a deep purple or nearly black hue. Although the berries are a highlight, they are not only decorative; they are also edible and can be used in jellies and pies, offering a mild, sweet flavor that is often likened to blueberries. The leaves of 'Robin Hill' serviceberry are oval to round in shape with fine, toothed edges, providing a lush, green backdrop for the flowers and fruit. In autumn, the foliage undergoes a dramatic change, showcasing a striking range of colors from yellow to orange and red before the leaves eventually drop. Throughout the growing seasons, the bark of the serviceberry remains an attractive feature, with its smooth, gray surface that may exude an additional visual interest to the observer, particularly during the dormant winter months when the leaves have fallen and the structure of the tree is more visible.

Water"Apple serviceberry" should be watered deeply to ensure moisture reaches the root zone, especially during its establishment period and dry spells. In the first growing season, water about 2 gallons per week, ensuring the soil is consistently moist but not waterlogged. Once established, they are quite drought-tolerant but will benefit from watering every two weeks if there is no significant rainfall. Adjust the amount based on weather conditions, with more water during hot, dry periods and less during cooler, rainy spells.
Light"Apple serviceberry" prefers full sun to partial shade for optimal growth and best flowering results. Full sun, meaning at least 6 to 8 hours of direct sunlight daily, is ideal for this plant, although it can tolerate some light shade. When in partial shade, ensure it receives at least 4 hours of direct sunlight, especially morning sun which is less intense.
Temperature"Apple serviceberry" thrives in a wide range of temperatures and can survive minimum winter temperatures down to about -20°F. It can tolerate summer heat well, but extreme temperatures over 95°F may stress the plant. The ideal growing temperatures are between 60°F and 75°F for vigorous growth and flowering.
PruningPruning "Apple serviceberry" is crucial for shaping the tree, removing dead or diseased wood, and promoting a strong structure. It's best to prune in late winter or early spring before new growth starts. Thinning out crowded branches every 2-3 years allows light and air to reach the inner canopy, which is beneficial for the plant's health and blooming.

Life cycleAmelanchier × grandiflora 'Robin Hill', commonly known as the 'Robin Hill' Serviceberry, begins its life cycle with seed germination, which requires stratification to break dormancy. Following germination, the seedling grows through vegetative stages, developing a root system and foliage. It then matures into a flowering plant, typically producing white-pink blossoms in early spring, which are pollinated by insects, leading to fruit set. The fruits, which mature into small pome-like berries by late summer, are eaten by birds and other wildlife, dispersing the seeds to promote new growth cycles. Over time, the 'Robin Hill' Serviceberry reaches a mature, reproductive phase where it can produce seeds annually, and under optimal conditions, it may live and thrive for several decades. In its declining phase, the plant's growth slows, and it may become more susceptible to diseases and pests, eventually leading to senescence and death.
PropogationPropogation time
Early Spring
The Serviceberry 'Robin Hill' is commonly propagated by softwood cuttings. Softwood cuttings are typically taken in late spring or early summer when the new growth is still tender and green, but has begun to mature slightly. To propagate by this method, a gardener would cut a 4 to 6 inch (10 to 15 cm) length of stem that includes a few leaves, ensuring that at least one node (where the leaves attach to the stem) is below the surface when planted. The cut end is often dipped in rooting hormone to encourage root development and then inserted into a well-draining soil mix. The cutting should be kept under high humidity, using a plastic cover if necessary, and in indirect sunlight until roots have formed, which usually takes several weeks. Once rooted, the cutting can be transplanted into a larger pot or directly into the garden.
