The genus deutzia is comprised of 60 flowering plants that are all part of the hydrangea botanical family (hydrangeaceae). They produce clusters of beautiful flowers in a similar fashion to the hydrangea plant.
Deutzia shrubs are a wonderful choice for a garden plant if you happen to live in an area that is covered by large trees. Though we love trees around here, there aren’t many flowering plants that are shade tolerant! But when it comes to the deutzia, they are capable of a prosperous bloom season in full shade.
The deutzia plant is just one of many species that we cover in our huge list of Beautiful Flowering Plants from all over the world. We cover everything from succulents, to ornamental grasses, to shrubs, and much more!

What do Deutzia Shrubs Look Like?
Deutzia shrubs produce flowers in the form of stunning racemes. These flower clusters are very similar in appearance to hydrangea flowers.
Some deutzia flowers are more elongated in shape, while others are gently drooping, and some are bell shaped. Certain species will bear flowers in panicles of corymbs.
Flowers will appear for just a short 2 weeks during the early spring or mid summer. They will usually emerge as elegant pink flowers, but may also be white or red.
Once a flower is pollinated it will produce fruit in the form of a small dry capsule that contains many small seeds. These capsules will then dry up and release the seeds which will then be wind dispersed or dispersed through animal droppings.
Deutzia shrubs will be either deciduous or evergreen depending on their growing region. They will keep their leaves in warmer climates, but will shed them in colder climates.
A deutzia leaf is simple in shape with a serrated margin. It is oppositely arranged along the stem. Leaves are a light green color, though certain species will develop leaves with a beautiful fall color in autumn.
Deutzia shrubs will vary in size, but will usually grow to be between 1 and 4 metres in height. This multi stemmed deciduous shrub will stand either erect or exhibit more of a ground cover mounded habit.
Branches grow in an arching habit which gives the appearance of a cascading or weeping shrub. In the winter, bark will peel away to reveal a beautiful orange color, bringing ornamental value into the winter months, too!
What are some Common Deutzia Species?
Fuzzy Deutzia (Deutzia Scabra)
The fuzzy deutzia is one of the oldest varieties in cultivation, and has been present in Japanese ornamental gardens for centuries.
This flowering shrub grows up to 3 metres tall and produces clusters of small white flowers that resemble cotton balls, hence the name, fuzzy deutzia.
This ornamental variety is wonderfully shade tolerant. It will still bloom profusely if it exists in full shade conditions.
Slender Deutzia (Deutzia Gracilis)
The slender deutzia is by far the most popular of the deutzia species for ornamental planting. They are a specimen that can bear a white flower that blooms in the late spring.
This plant will usually grow to be about 1 metre tall, but there is a cultivar called the deutzia gracilis ‘nikko that has been cultivated to be about half of that size. It is valued for its arching branches that touch the soil and take root, creating new specimens.
This variety can tolerate nearly any level of sun exposure, a great variety of soils, and is a wonderfully resilient plant that is easy to propagate.
Yuki Cherry Blossom (Deutzia x Yuki Cherry Blossom)
The yuki cherry blossom is a very new deutzia cultivar, and it is the first ever to bear pink flowers! Gardeners everywhere are very excited.
This variety produces pink flowers that are bell shaped and bloom in the early spring. It is a shade tolerant plant that is also naturally deer resistant.
It is often used for mass planting because of its carpet of flower color and its attractive mounded growth habit. It is a wonderful option for a ground cover plant.
Where are Deutzia Plants Native to?
Deutzia plants cover a wide growing range, and they are native plants to eastern and central Asia. They also grow in the wild in central America and Europe. They grow most prosperously from the Himalayas, eastward to Japan and throughout the Philippines as well.
These plants are both cold hardy and tolerant of heat. In colder far eastern regions they are a deciduous shrub that will re-bloom once winter is over. In more mild climates (like certain European countries) they tend to flower quite early, though it is often spoiled but unexpected frost.
What are the Growing Conditions of Deutzias?
Deutzias are wonderfully simple to care for, which is not always the case with such beautiful specimens. Whether you’re looking to plant them right in the ground or in outdoor pots, any skill level of gardener can successfully incorporate their own deutzia shrub as long as they can abide by the following requirements:
Deutzia plants can tolerate many different soil types derived from almost anything, though they prefers soils that are humus loam. Acidity level may also vary.
Soil should be well drained and kept moist. This plant can be damaged by poorly drained soils or young plants can perish from soil that remains dry for too long.
It tends to vary from species to species, but many deutzia plants are wonderfully shade tolerant. There are some that prefer to live in full sun or partial shade, but many species will still experience a full and prosperous blooming season in full shade – this is quite rare for flowering plants!
Deutzia plants require a moderate level of water and will usually do fine with natural precipitation and humidity in their natural growing ranges. Simply ensure that soil remains moist, though well established plants are very drought tolerant.
Deutzias are moderately cold hardy, and exist in USDA growing zones 5 through 8. They will usually drop their fall color leaves in colder climates, but will remain evergreen in warmer climates.
The most high maintenance aspect of the deutzia shrub is pruning. A good prune is required every year in order for the plant to look its absolute best. Pruning should always be done immediately after they have finished flowering.
It will flower on second years’ growth, and it you prune too late in the season there is the risk of accidentally pruning away the flower buds, and effectively removing the possibility of the following years bloom.
It is suggested to wait to use fertilizer on a deutzia shrub until after their first active growing period. Once the plant is better established, it will respond positively to a light and balanced granular fertilizer.
Fertilizing your shrub increases the possibility of a more prosperous and lengthy blooming season, and will help the shrub grow back vigorously after it is pruned.
As you can see, the deutzia is a surprisingly easy plant to care for! It does not have any strict intolerances – other than waterlogged soils – but this is the case with most plants!
How is the Deutzia Plant Used?
Deutzias are valued for their stunning racemes of white flowers and pink flowers, and many have been in cultivation for centuries because of this ornamental flora.
These beautiful landscape plants can be used for mass planting, as a shrub border plant, they are often planted in outdoor containers, or can be used as facer plants (to help cover the bases of larger shrubs).
