Also referred to as Clematis terniflora, Japanese Clematis, Clematis paniculata, and Clematis dioscoreifolia, this versatile vine is particularly known for its prolific flowering in the autumn months.
With masses of fragrant white blooms and attractive green foliage, Clematis maximowicziana is an excellent choice for gardeners who desire a dramatic and fragrant display in the fall.
How to Grow and Care for Clematis maximowicziana
Clematis maximowicziana is relatively easy to grow and care for, but like all plants, it has specific requirements that must be met to ensure it thrives.
In good soil with appropriate mulch to provide a cool root run this is a plant that survives hot dry summers with little to no extra water.
Basic Tips
- Plant in a humus rich well drained soil.
- Amend poorer soils with organic matter such as leaf mould, or well rotted compost and some aged cow manure before plating.
- Choose a position where the root system will be in shade or at least very well mulched.
Detailed growing Notes
Planting Location
Choose a location that provides plenty of sunlight for the plant’s growth. However, the key to success lies in ensuring that the root system is shaded or well-mulched to keep it cool and protected from excessive heat.
Clematis maximowicziana does well when its roots are kept in the shade, while the rest of the plant is allowed to bask in full sun. This combination helps the plant thrive, offering a balance of sunlight and cooler conditions for its roots.
Soil Requirements
For optimal growth, Clematis maximowicziana prefers humus-rich, well-drained soil. If your garden soil is on the poorer side, it’s essential to amend it before planting. This can be done by incorporating organic matter such as leaf mold, well-rotted compost, and aged cow manure into the soil. This organic matter will improve soil structure, promote healthy root growth, and enhance moisture retention.
Watering
Clematis maximowicziana is relatively drought-tolerant once established, making it an ideal plant for gardeners who may not have time for frequent watering. However, to promote abundant flowers and overall plant health, regular watering during dry spells is advisable. If the soil is well-mulched, the plant will fare even better, as mulch helps retain moisture and reduces the need for frequent watering.
While the plant is somewhat tolerant of drought, providing deep, infrequent soakings during prolonged dry periods ensures that Clematis maximowicziana produces an impressive number of flower buds. The more flowers it produces, the more spectacular the autumn display will be.
If is well mulched it will survive hot summers with little to extra water. However a few good soakings over long dry periods will help ensure masses of flower buds and therefore that ‘wall of flowers’ you are looking forward to.
Pruning
Clematis maximowicziana is a type of clematis that flowers on new growth, meaning it is important to prune the plant in winter to encourage vigorous blooms in the following season.
The best time to prune this clematis is in late winter or early spring, before new growth begins. Simply cut back the plant by about one-third (or more, depending on its size) to a height of around one meter (3 feet).
This pruning method encourages strong, healthy new growth and helps maintain the plant’s shape, ensuring a prolific flower display come autumn.

Propagation
Clematis maximowicziana is easy to propagate through cuttings, making it a great plant to share with friends or expand your own garden.
Take semi-ripe cuttings from healthy stems in summer or early autumn, dip the cut ends in rooting hormone, and place them in a container with a well-draining potting mix.
Keep the cuttings in a warm, shaded spot until they root, and then transfer them to their final planting location.
With patience and proper care, you’ll be able to grow additional clematis vines to enjoy or share with others.
