Newport plum trees (Prunus cerasifera ‘Newportii’) provide several seasons of interest as well as food for small mammals and birds.

The plant is native to Asia but many cooler to temperate regions of North America are suitable for growing Newport plum. What is a Newport plum? Continue reading for a description and cultural tips on this pretty tree.

What is a Newport Plum?

While Newport plum does produce some fruits, they are considered of minimal palatability to humans. However, birds, squirrels and other animals utilize them as an important food source. It is a medium sized tree useful in containers, as bonsai, or standalone specimens. The tree has a slow to moderate growth rate making it perfect as an urban shade plant.

Newport plum trees are often used as ornamental shade plants. It is a deciduous tree that grows 15 to 20 feet (4.5 to 6 m.) tall with spectacular purple-bronze foliage. Springtime brings sweet little purplish pink blossoms and lovely purple drupes form in summer. Even once the leaves and fruits are gone, the upright, vase-like form of the branches creates an attractive scene when covered in winter’s snowy glory.

Newport plum care is minimal once established. The plant is useful in United States department of Agriculture zones 4 to 7 and has excellent winter hardiness.

How to Grow a Newport Plum

The ornamental plum requires full sun and well-draining, acidic soil. Moderately alkaline soils are fine too, but leaf color may be compromised.

Newport plum trees like quite a bit of rainfall and moist soil. It has some short term drought tolerance once established and can withstand sea spray.

During the spring, bees will flock to the tree’s blooms and during late summer to fall, birds feast on the handing or dropped fruits.

The most common method of growing Newport plum is from cuttings, although seed grown trees are possible with some variation of form from the parent.

Newport Plum Care

This is a relatively easy tree to care for provided it is situated in moist, well-draining soil. The biggest issues are fruit and leaf drop, and some pruning may be necessary to shape the tree and keep a strong scaffold. The branches are not particularly fragile, but removal of any damaged or broken plant material should be done in late winter to early spring.

Unfortunately, the plant seems susceptible to several species of borers. Watch for signs of frass and use appropriate pesticides when necessary. Aphids, scale, Japanese beetles and tent caterpillars may also be a problem. Disease problems are generally confined to fungal leaf spots and cankers.

Flowering Plum Tree

The Flowering Plum tree is very pretty small ornamental tree. The botanical name is Prunus cerasifera. You will probably want a purple leaf variety. It flowers in the spring with small pink flowers. The light pink against the purple leaves is very attractive!

You can see how vivid the red color is in the photos below. The first photo was taken at a house I lived in. I can honestly say I enjoyed this tree almost all year long.

There are a few different varieties of the Flowering Plum tree so I will narrow it down to the best one.

I would recommend the Newport Plum. This purple leaf plum tree is the hardiest one.

The new leaves are a light bronze-purple color but then they change to a reddish/dark purple. The pink flowers cover the tree and is lovely when in full bloom, which is very early in the spring. This tree is also a fast grower.

  • very pretty rounded/symmetrical shape
  • reddish purple leaves makes it stand out in the landscape all season long
  • its small size makes it desirable and easy to place

Where To Use The Purple Leaf Plum Tree

This tree is lovely as a focal point. You can do this by placing it out in the lawn. You can use just one, but if you have the space, you can stagger them across the lawn and use three. Place two a little closer together and one further away in a triangular design.

This Plum tree is small enough to also use at a house corner. Place it about 10 feet away from the house to allow room for growth. This is very doable in a design as you can sweep the bed around it and add plants behind the tree as a background. You can also add plants in front of it.

Place it near your patio where it will not only be nice to look at from the patio and inside your house, but also will provide some shade.

Use one at your driveway entry or use two on either side for a more symmetrical look. They can be used alone, or you can create a planting bed around them with shrubs and perennials.

If diseased branches are discovered, remove them immediately. Insecticides and fungicides can be used to deter wood borers and other mildew diseases, like cherry leaf spot.

Pruning

Pruning is essential for not just maintaining the shape and training the tree to a desired size but also in promoting healthy plant tissue especially when there are dead or dying branches. Pruning also helps in flower bud and fruit growth. There are three ways to prune by crown reduction, thinning and pinching. Thinning helps in removal of weak limbs and stems while pinching of flower heads and twiggy offshoots help in controlling the plant’s size. To maintain the tree’s canopy and shape use crown reduction which involves removal of top portion of the tree has to be done.

Start pruning to shape young trees, just make sure you don’t cut the main branch. Just snip out a few lateral steams to either maintain a design or encourage strong growth. The best time to prune a flowering plum is during their dormant period. Remove all diseased, damaged and weak branches. If a well-shaped crown is what you are aiming for then prune lower branches, or in dense crowns cut away some of the larger branches at the top of the tree. Use sharp garden tools like shears, lopping shears, hand saws, etc to get a good job done. For shorter branches use clippers like scissor action pruners, and pole pruners for large branches. If the branches are thicker than one-inch, use curved pruning saws. For well-established trees ask for professional help if you are not too sure about the way to go.
