Purple leaf plum Prunus × blireana (d)
ABOUT
The Prunus × blireana, or Purple-leaf plum, is a visually striking ornamental tree known for its appealing aesthetic traits. The most eye-catching feature of this tree is its stunning display of spring blossoms. It produces an abundant profusion of double pink flowers that create a spectacular floral show, typically emerging before the foliage. These blossoms provide a sharp contrast against the dark branches and are a magnet for pollinators such as bees. Following the flowering period, the tree's foliage emerges, offering another layer of visual interest. The leaves are a rich purple or maroon color and maintain this hue throughout the growing season, adding a permanent splash of color to the landscape. The leaf shape is generally oval with a pointed tip and the edges can be finely toothed, providing a delicate and ornate texture. As the seasons change, the Purple-leaf plum will produce small, non-edible fruit that might not be particularly showy and often goes unnoticed, as it tends to blend in with the dark foliage. Overall, the plant is admired for its floral and foliage attributes, which can add an ornamental quality to any garden setting.

ToxicityTo humans
The most common common name of Prunus × blireana is the purple-leaf plum. Like other members of the Prunus genus, it contains compounds that can be toxic when ingested by humans. The plant, particularly the seeds, leaves, and stems, contain cyanogenic glycosides, which can release hydrogen cyanide when damaged or digested. Symptoms of poisoning from ingesting parts of the purple-leaf plum include headache, dizziness, difficulty breathing, nausea, vomiting, convulsions, and potentially, in severe cases, coma or death. The flesh of the fruit itself is generally considered safe to eat in moderation, but caution should always be exercised to avoid consuming the other parts of the plant.
To pets
The purple-leaf plum, Prunus × blireana, is also toxic to pets due to the presence of cyanogenic glycosides in its leaves, stems, and seeds. If pets consume these parts of the plant, they may exhibit symptoms of cyanide poisoning. These can include panting, difficulty breathing, dilated pupils, bright red gums, and shock. In severe cases, ingestion can lead to coma or death. It is important for pet owners to prevent their animals from chewing on branches, leaves, or seeds of the purple-leaf plum to avoid the risk of poisoning.

WaterThe Purple-leafed plum tree should be watered deeply, ensuring that water reaches the roots, approximately once a week during the growing season and less frequently during the dormant season. A guideline for young trees is to provide about 15-20 gallons of water per week. It's essential to adjust watering based on rainfall, as overwatering can lead to root rot. During hot, dry periods, you may need to water more frequently, while in cooler, wetter months, you may water less. Avoid shallow watering as it doesn't encourage deep root growth, which helps the tree withstand drought conditions.
LightThe Purple-leafed plum tree thrives best in full sunlight, which promotes the healthiest growth and best flowering. A spot that receives at least six hours of direct sunlight per day is ideal. However, the tree can also tolerate partial shade, though it may affect the vibrancy of its flowers and foliage.
TemperatureThe Purple-leafed plum tree is hardy and can withstand a range of temperatures, from winter lows down to about -20°F to summer highs well into the 90s°F. Its ideal temperature range for thriving is between 60°F and 75°F. It is essential to ensure that the tree is well-watered during extreme temperatures, especially heat, to prevent stress.
PruningThe Purple-leafed plum tree should be pruned to maintain its shape, remove any dead or diseased branches, and encourage healthy growth. Pruning is best done in late winter or early spring before the tree starts budding. Annual pruning helps to prevent over-crowding of branches, which may lead to reduced air circulation and increased vulnerability to diseases.
CleaningAs needed
SoilThe best soil mix for the Purple-leaf Plum is well-draining loamy soil enriched with organic matter. The soil pH should be slightly acidic to neutral, ranging from 5.5 to 7.5.
RepottingPurple-leaf Plums, being outdoor ornamental trees, do not typically require repotting. They are usually planted directly in the ground and may only need replanting if they outgrow their space or for landscaping purposes.
Humidity & MistingPurple-leaf Plums are adaptable to a wide range of humidity conditions and do not have specific humidity requirements. They can tolerate the varying humidity levels commonly found outdoors.

Life cyclePrunus × blireana, commonly known as the Purple-leaf Plum or the Blireana Plum, begins its life cycle when a seed germinates in the soil after a period of cold stratification that breaks the seed's dormancy. The seedling emerges and develops into a young sapling, characterized by rapid growth and the establishment of root system. As it matures, the plant enters a vegetative stage, producing distinctive purple leaves and building up energy reserves. The Purple-leaf Plum then enters its reproductive phase, typically in early spring, showcasing pink to purplish flowers before leafing out. After pollination, often by bees, it sets fruit; however, the fruit is generally considered ornamental rather than edible and may not develop fully or reliably. Over time, the tree ages and enters a period of senescence, with reduced growth and reproductive output until eventually it dies.
PropogationPropogation time
Spring
Prunus × blireana, commonly known as the Purple-leaf Plum, is most effectively propagated using softwood cuttings. This method is typically carried out in late spring or early summer when the new growth is still tender and elastic. Cuttings of about 4 to 6 inches (10 to 15 centimeters) are taken from healthy branches, ensuring that at least two to three sets of leaves are present. The lower leaves should be removed, and the cut end can be treated with a rooting hormone to enhance root development. The cuttings are then inserted into a well-draining potting mix and kept under high humidity with a clear plastic cover to maintain moisture. The cuttings usually root within 4 to 8 weeks, after which they can gradually acclimate to less humid conditions and eventually be moved outdoors.
