Common Names
The common names for Prunus subcordata Benth. var. oregana include Oregon plum, bitter cherry, wild cherry, and western chokecherry.
Uses
Prunus subcordata Benth. var. oregana has a variety of uses. The fruit of the Oregon plum is edible, but often too sour or bitter for human consumption. However, it is a valuable food source for birds and mammals. The wood of the tree is hard and dense, making it useful for tool handles and furniture, and it is also a source of fuelwood. Native American tribes used the bark of the tree for medicinal purposes, including treating stomach pains and sore throats.

They are glossy green and have finely serrated edges. The tree blooms from March to June with clusters of white, fragrant flowers. The fruit it produces is a small, dark purple drupe that resembles a cherry and typically ripens in late summer.
Light Requirements
Prunus subcordata Benth. var. oregana typically grows in partial to full shade conditions. It is well suited for shady locations under a dense tree canopy, but can also tolerate partial sunlight. In general, it prefers areas with varying degrees of shade throughout the day.
Temperature Requirements
The plant can grow in a wide range of temperatures, from cold to warm. It tolerates temperatures as low as -28°C and as high as 38°C. However, it grows best in regions with cool to moderate temperatures. In the wild, it is found growing in regions with a continental or maritime climate.
Soil Requirements
The soil type preferred by Prunus subcordata Benth. var. oregana is moist, well-drained, and slightly acidic with a pH range between 6.0 and 6.5. It grows well in soils with good organic matter content. The plant can tolerate a wide variety of soil types including loam, sand, and clay soils. It is typically found growing near streams or in moist, shaded environments.
Cultivation Methods
The Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck plant is a native to the western regions of North America, where it grows and finds its habitat. If you plan on cultivating this plant, it's crucial to know its growing conditions and requirements.
This plant grows best in sandy or rocky soils with either neutral or acidic pH levels. The Prunus subcordata var. oregana prefers a lot of sunlight and will thrive in open areas with at least six hours of sun every day. Before planting the plant, ensure that the soil is well-draining to prevent root rot.
You can propagate Prunus subcordata var. oregana through seeds or cuttings. If you decide to propagate through cuttings, make sure that you take them from dormant wood in late fall or early winter. You can then plant the cuttings directly into the soil, making sure that the soil remains moist throughout their growth period.
Watering Needs
The Prunus subcordata var. oregana prefers a moist soil but can also tolerate dry spells once it's established. During the first year of planting, you should water this plant regularly and ensure that the soil remains moist. After the first year, you can reduce the frequency of watering, especially if there's enough rainfall in your area. Do not overwater, as this can lead to root rot.
Fertilization
Prunus subcordata var. oregana is not a heavy feeder, and in most cases, it won't require any fertilizers. However, if you observe slow growth or yellowing of leaves, it's an indicator that the plant needs fertilization. You can use a balanced fertilizer once a year to provide the needed nutrients.
Pruning
Prunus subcordata var. oregana requires little to no pruning, as it naturally grows into an upright and well-formed shrub. However, you can prune the plant to control its size or shape. The best time to prune this plant is in late winter before the growth season begins. You can remove any dead or damaged branches and thin out any congested areas to improve air circulation and sunlight penetration.
With proper care and cultivation methods, Prunus subcordata var. oregana can offer your garden a beautiful flowering shrub, serving as an attraction to hummingbirds and other pollinators.
Propagation of Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck
The Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck plant can be propagated through several methods, including:
1. Seeds
Seed propagation is the most common method for growing Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck plants. The seeds can be collected from the plant when they are ripe, usually in late summer or early fall. The seeds should be sown immediately after collection, or they can be stored in a cool, dry place until spring. The seeds should be sown in a well-draining soil mixture and kept moist until the seedlings emerge.
2. Cuttings
Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck can also be propagated through stem cuttings. The cuttings should be taken from softwood or semi-hardwood growth in the summer or early fall. They should be about 4-6 inches long, with at least two sets of leaves. The leaves on the lower half of the cutting should be removed, and the cutting should be dipped in rooting hormone. The cutting should be planted in a well-draining soil mixture and kept moist until roots develop.
3. Grafting
Grafting is another method of propagation for Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck. It involves grafting a scion of the desired plant onto the rootstock of a related plant. The grafting should be done in the spring, using a whip graft or a side veneer graft. The graft should be wrapped with grafting tape and kept in a warm, humid environment until the graft union has formed.
Disease and Pest Management for Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck
Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck is a beautiful, deciduous tree that is commonly known as bitter cherry. It is often used for ornamental purposes and is also occasionally used as a rootstock for sweet cherry varieties. Like all plants, it is susceptible to a range of diseases and pests that can significantly impact its growth and ability to produce fruit.
Common Diseases
One of the primary diseases that can affect bitter cherry is bacterial canker. This disease is caused by the bacterium Pseudomonas syringae and can cause wilting, cankers, and gummosis. Control measures for bacterial canker include pruning infected branches and improving overall tree health to minimize stress.
Brown rot is another common disease that can affect bitter cherry. This disease is caused by the fungus Monilinia fructicola and can cause fruit rot and twig blight. Control measures for brown rot include removing infected fruit and increasing air circulation around the tree.
Common Pests
One of the primary pests that can affect bitter cherry is the western cherry fruit fly. This pest lays eggs in the fruit and can cause significant damage to fruit production. Control measures for the western cherry fruit fly include using pheromone traps, removing infected fruit, and applying insecticides.
Another common pest that can affect bitter cherry is the cherry slug. These pests are the larvae of sawfly species and can cause significant defoliation of the tree. Control measures for cherry slugs include removing affected leaves and applying insecticides.
Integrated Pest Management
Integrated Pest Management (IPM) is a holistic approach to managing pests that includes a combination of cultural, biological, and chemical control methods. For bitter cherry, IPM strategies may include maintaining tree health, pruning to increase air circulation, and introducing beneficial insects to control pest populations.
By following these disease and pest management strategies, growers can help ensure the health and productivity of their Prunus subcordata Benth. var. oregana (Greene) W. Wight ex M.E. Peck trees and enjoy a bountiful harvest of delicious fruit.
