Purple-Leaf Plum Tree: Growing and Caring for Ornamental Plums

Purple-leaf plum trees—also known as cherry plum, myrobalan plum, or flowering plum—are celebrated for their dramatic dark foliage, fragrant spring flowers, and versatile landscape appeal. These deciduous trees bring lasting color and seasonal interest to gardens and urban landscapes, making them a top pick for homeowners and designers who want to add a vivid splash to their outdoor spaces.

What is a Purple-Leaf Plum Tree?

The purple-leaf plum (Prunus cerasifera) is a medium-sized ornamental tree native to Western Asia and the Caucasus, widely cultivated for its deep red to purple leaves and profuse spring bloom of fragrant white to light pink flowers. Grown mainly for visual impact, these trees are fast-growing and offer both beauty and function in gardens across hardiness zones 5 through 8.

• Botanical name: Prunus cerasifera and cultivars
• Common names: Purple-leaf plum, cherry plum, flowering plum, myrobalan plum, wild cherry plum
• Height/spread at maturity: Typically 15–25 feet tall and wide
• Zones: 5–8
• Foliage: Deep red to purple, sometimes with glossy or matte texture
• Flowers: Abundant, fragrant, white to light pink in early spring
• Fruit: Small, edible, cherry-like drupes—attractive to birds
• Growth rate: Moderate (1–2 feet per year)

Benefits of Adding a Purple-Leaf Plum to Your Landscape

• Vibrant Foliage: The dramatic purple foliage stands out in mixed plantings, adding instant contrast and curb appeal.
• Spring Blooms: Showy, fragrant blossoms attract pollinators and mark the arrival of spring.
• Wildlife Value: The tree’s small fruits provide food for birds and small wildlife.
• Multiple Uses: Suitable as a specimen, accent, or even as a flowering hedge or screen.

Growing Purple-Leaf Plum Trees

Successfully growing a purple-leaf plum tree requires attention to site selection, planting, and ongoing care. Here’s how to get started and keep your tree healthy:

Site Selection

• Sunlight: Full sun (6–8 hours per day) is essential for maintaining vibrant leaf color. In shade, the leaves may revert to green or appear less vivid.
• Soil: Prefers well-draining, loamy soil. Tolerates a pH from 5.0 to 7.0 (acidic to neutral), and is adaptable to clay or sandy soils if drainage is good.
• Placement: Plant away from walkways and patios to avoid fruit mess, and provide space for the tree’s mature width.

Planting Instructions

1. Dig a hole 2–3 times as wide and as deep as the root ball.
2. Gently loosen the root ball and place the tree in the hole at the same depth as it was growing in the container.
3. Backfill with native soil blended with compost or mulch for added nutrients and moisture retention.
4. Water thoroughly after planting, and mulch around the base to conserve moisture and suppress weeds.

Watering

• Maintain moderate, consistent moisture, especially during the growing season (spring to autumn).
• Once established, trees are moderately drought-tolerant, but benefit from supplemental watering during heatwaves or dry spells.

Fertilizing

• Apply a balanced, all-purpose fertilizer in early spring as new growth begins.
• If the soil is already fertile, fertilize every 2–3 years instead of annually.

Pruning

• Lightly prune after flowering to maintain the desired shape and remove any dead, diseased, or crossing branches.
• Minimal pruning helps develop a strong structure and promotes healthy air circulation.

Temperature & Hardiness

• Cold hardy to -20°F (zone 5); tolerates both cold winters and hot summers when adequately watered.
• Humidity rarely poses a problem for healthy trees.

Soil and Transplanting Tips

• Rich, organic, well-drained soil ensures vigorous growth and reduces stress after transplanting.
• Incorporate mulch and root stimulator after planting to reduce transplant shock.

6 Common Purple-Leaf Plum Varieties

There are several cultivars of purple-leaf plum, each with unique growth habits, flower color, and leaf tones. Here are the most popular options:

Design Tips: Using Purple-Leaf Plum in the Landscape

• Specimen Tree: Plant as a focal point in the lawn or near entryways, where its color and flowers can be enjoyed up close.
• Color Contrast: Use against green-leaved trees, light-colored walls, or evergreen backdrops to make the purple foliage stand out.
• Mixed Plantings: Combine with liriope, ornamental grasses, or yellow-foliaged shrubs for striking combinations.
• Hedges & Screens: Several plum trees planted in a row create a vibrant, flowering hedge in spring and a privacy screen through summer.
• Small Gardens: Dwarf and compact varieties fit into tight spaces, patios, or urban courtyards.

Common Problems and Concerns

• Short Life Span: Most purple-leaf plum trees are relatively short-lived, averaging 20 years, especially in urban or stressful environments.
• Disease Susceptibility: Vulnerable to fungal diseases (such as leaf spot), Texas root rot, cankers, and aphids, especially if stressed by drought or poor soil.
• Fruit Drop: Can be messy if planted near walkways, as dropped fruit may stain and attract wildlife.
• Invasiveness: In some regions, these trees can self-seed prolifically, but they are not widely recognized as an invasive threat in the United States.

Is Purple-Leaf Plum Invasive?

Purple-leaf plum trees may self-seed and naturalize in some areas, but they are not considered highly invasive in most North American landscapes. Regular pruning and fruit collection reduce the risk of spreading. Always check with local extension offices for the latest guidance on species behavior in your region.

Is Purple-Leaf Plum Fruit Edible?

The fruits of the purple-leaf plum are technically edible and resemble small cherries, usually ripening to red or purple in late summer. While not as sweet as cultivated plums, they are safe to eat and suitable for making preserves or jams. However, fruit flavor and production can vary between cultivars and growing conditions.

Note: Always confirm tree identity before consuming any fruit, and avoid eating seeds or pits, as they contain cyanogenic compounds like many stone fruits.
