How to grow Japanese anemones

Last Updated on

If you want to have a late summer flowering garden, Japanese anemones are a great addition. The flowers are held up on wiry stems and can be found in a variety of colours including pink, lavender, or white. You can find single or double flowers all of which both yellow centres. They’ve nicknamed the Windflower because of how easily they dance in the wind. These particular flowers differ from bulbing anemones which otherwise bloom in Spring. The Japanese anemone is a perennial that blooms in the Autumn so you can enjoy a range of colour at the end of summer so long as you have an area that has moist soil with partial sun.

Native to China, these flowers were heavily cultivated in Japanese Gardens where they were seen first by European explorers during the 17th century. The late summer flowers and the dark green foliage that dancing the wind made them particularly attractive. They grow well in full sun or partial shade and can be quite tall so they will fill up the back of a layered space effectively. They spread via rhizomes but, you can remove errant plants easily in the spring.

Where to Plant Japanese anemones

If you live in a colder area, you should plant your Japanese anemones close to a structure such as a fence or a wall or house so that they have extra protection against the winter weather. They make for great flowers to plant along the border of your home or outdoor shed. If you don’t have such a space-available you can grow them in a large container suitable to the size of the root system at full maturity, and place them in areas like patios or balconies where they still get that added protection thanks to the structures around the containers.

When to Plant

You should plant new Japanese anemones in the springtime once there is no longer a risk of frost. The roots don’t like to dry out so you need to make sure where you plant them they will be able to stay moist, something you can help with a little extra mulch. They do best with humus-rich soil and a mixture of compost. If you are planting more than one, space them out approximately 1/2 meter from one another as they do quickly fill out and area.

They prefer moist well-drained soil

As long as the soil is well-drained hanging and stays moist Japanese anemones are quite forgiving. This means you don’t have to go out of your way to test the pH level or amend slightly sandy or clay-like soil. However, you still need to give them some regular care no matter the soil type. 

Maintaining Japanese Anemones

Firstly, they will need compost in the spring. Secondly, to help with moisture retention and to prevent weeds from taking over you should add bark mulch every season around the base of the plant.

Support taller varieties with canes

The Japanese anemones can grow over one meter in height and if you have the double-flowered varieties you might need to add some canes or some sort of support to prevent them from falling over.

Dividing plants

They will spread runners underground so after the first few years, you can divide an existing plant and transplant them elsewhere. To do this dig up the entire plant at the beginning of Spring, divided into fist-sized new plants, and replant them in similar conditions.

Winter care

In the winter frost has killed the plants, you can cut them back to ground level and add compost over the top. Rest assured, they will come back in the spring just fine.

They do best when you grow them in groups and give them room to spread. They will also attract butterflies so you can add them to a wildlife garden or other woodland area where they will be allowed to spread naturally. If you need to pair them with other plants to fill the garden space, you can do ornamental grasses, hosta, even monkshood.
