How Japanese Anemone looks like

Japanese Anemone is a perennial plant also known as anemone x hybrida or windflower.

Its cultivars are in a star or cup in the shaped flower with a green button in the center. The flowers are single, semi-double, or double and white to mauve, and dark pink in color.

The foliage of the plant is dark green and has hairy or glossy undersides. The plant forms a robust clump that grows nearly 5 feet in height.

It is a good idea to plant them in early spring so that they can produce beautiful colors and shape bloom in fall. They also attract pollinators like butterflies and bees. 

They are salt, deer, and rabbit resistant. But if you have a pet in the house don’t plant a Japanese Anemone. All anemone plants are poisonous when eaten. Planting them in your garden will risk the life of your beloved pet.

  • Zones: 4 – 7 (depending on the variety)
  • Sun: Part Shade To Sun
  • Height x Width:  5 feet x 4 feet
  • Bloom Time: Fall

Japanese Anemone grows in partial shade but they can also tolerate full sun. Like other plants, the further north in their growing range, the more light they can get.

The height of the Windflower also depends upon the amount of light it gets. Generally, planting anemones in the shade leads to taller stems whereas in the full sun they are considered shorter.

These perennials tend to spread out every year by rhizomes and create a good clump.  The roots of this perennial grow underground, don’t plant them in a pot or container.

I recommend planting them in an open spot where they get ideal space to spread.

These plants are invasive, you have to chop off new shoots once they grow bigger otherwise it’ll take over nearby plants. If you live in the northern region then don’t worry much. They spread slowly in the north zone.

Planting Japanese anemones in the standard fertile clay soil but not in a wet location makes sure they’ll grow well.

How to care for Japanese Anemone

Besides being a beautiful fall flower they are also very easy to maintain. They like moist and well-drained soil so you have to water them from time to time.  

If you plant them in a sunny spot then the soil gets quickly dry and needs more water. For better results, you should plant them in partial shade and water occasionally.

Other than water these plants don’t need much care. To encourage the bloom you can deadhead the flowers. Deadhead to make your plant look neat.

If your plant is growing well and has a very tall stem then you have to stalk them loosely so that they don’t bend in the wind.

Anemone plants bloom in the fall and go dormant in the spring. They make a perfect combination with spring bulbs like tulips and daffodils. As the bulbs finish blooming, an anemone comes out and hides the foliage of the spring bulbs.

Planting them with fern peonies also works well, it blooms in early spring and goes dormant in the summer.

No doubt Japanese anemone is one of the best perennial fall flowers to grow in your garden. You should definitely plant them in your garden to have some beautiful colors.
