Care when arranging in a vase

When arranging in a vase, the important thing is to regularly change the water and keep the vase clean. To make the flowers last longer, it's recommended to make small slits in the stem's cut end with pruning shears. This process helps the plant absorb water more easily.

Also, it's important to remove the lower flowers before arranging to prevent them from soaking in the water. If flowers are left in the water, it can lead to poor water quality in the vase and promote bacterial growth.

Spiraea thunbergii Care Instructions

To enjoy branches for as long as possible, daily care is essential. Here, we'll explain the basic care methods for commonly available branches, including Spiraea thunbergii.

Basic Care

1. Recutting and Water Absorption on the Day of Receipt

Upon receiving the branches, recut them before placing them in a vase.

Additionally, make a cross-shaped cut at the base and use a knife to peel off the surface bark of the stem. It's recommended to peel only the part that will be submerged in water. This makes it easier for the plant to absorb water, extending the freshness of the branches.

Furthermore, using a freshness preservative can help maintain the freshness of the branches even longer.

 

2. Strategic Placement of Branches

Spiraea thunbergii prefers well-ventilated, sunny, and moderately humid locations. Placing them in a bright spot, such as near a window, will help them thrive.

However, direct exposure to air conditioning can cause them to dry out and reduce flowering, so be careful.

 

3. Frequent Water Changes

Water quickly becomes cloudy if left unattended. It's recommended to change the water regularly before this happens.

If there are any slimy parts on the stem, gently rub them off by hand.

What to do if your branches start to lose vitality...

Cut the branches short and enjoy them in smaller arrangements.

Although branches are relatively sturdy and long-lasting, it's inevitable that they will gradually absorb less water as days pass.

If they start to look a little less vibrant, why not try cutting the branches shorter and arranging them differently?

By arranging them in smaller vases, you can create a different impression ◎

Try to find ways to enjoy your branches for even longer.

Spiraea thunbergii Trivia

Difference between Spiraea thunbergii and Spiraea cantoniensis

A flower often compared to Spiraea thunbergii is Spiraea cantoniensis (Kodomari). Both are popular spring branch plants that appear around the same early spring season. Both are deciduous shrubs belonging to the rose family, Spiraea genus, and their magnificent flower forms, bearing small white flowers, look similar.

To distinguish between the two plants, their names effectively describe their characteristics.

Spiraea cantoniensis has small white flowers clustered together to form a round ball, like a small temari ball, while Spiraea thunbergii has numerous small, snow-like flowers blooming profusely on its arching, willow-like branches.

Incidentally, Odemari (Viburnum plicatum), which looks very similar, belongs to the Adoxaceae family, not the rose family.

Both are representative branch plants that beautifully adorn the spring season.

Spiraea thunbergii's scientific name was given by Siebold

Delving into the origins of plant scientific names can reveal interesting histories and anecdotes.

The scientific name for Spiraea thunbergii is Spiraea thunbergii. This name was supposedly given by Siebold, a German physician and naturalist who came to Japan in the late Edo period and introduced Western learning to the country.

"Spiraea" is Greek for "spiral," named because the leaves of Spiraea thunbergii grow in a spiral pattern.

"thunbergii" is named after Carl Peter Thunberg, a Swedish physician and botanist who worked at the Dutch trading post in Dejima, Nagasaki, during the mid-Edo period (1775-76).

Siebold, a historically famous figure in Japan, came to Japan by government order in the late Edo period (1823-28) and stayed at the Dutch trading post. It is said that he named the plant in honor of his senior, Carl Peter Thunberg, who had arrived in Japan earlier.

One of Siebold's objectives in coming to Japan was to cultivate scholars of Dutch studies and research Japan's flora and fauna. During his six-year stay, he collected many plants and compiled books on Japanese flora and fauna after returning home. In his work "Flora Japonica," he mentions Spiraea thunbergii, showing a strong interest in it.

Tracing back from the scientific name of Spiraea thunbergii to Siebold's life and the history of the Netherlands and Japan at the time, one can truly appreciate that this delicate and ephemeral white flower has inhabited and been cherished in Japan since ancient times.

"Root Steaming" of Spiraea thunbergii

Fukushima Prefecture is a thriving area for the cultivation of Spiraea thunbergii as a branch plant. In Sukagawa City, a leading production area nationwide, unlike other regions, Spiraea thunbergii to be shipped are dug up entirely and "root-steamed" in greenhouses for about two weeks.

This "root steaming" allows the blooming period to be adjusted to meet demand, and since the plants remain attached to their roots until just before shipping, the flowers last longer after blooming.

However, because the plants are dug up entirely, it is very labor-intensive, and in recent years, shipping volumes have been decreasing.

Spiraea thunbergii can be enjoyed all year round

As a branch plant, Spiraea thunbergii is widely available from January to March. Its hard stems absorb water well, so frequent recutting and water changes are necessary.

Spiraea thunbergii is famous as a spring flower with many lovely white blossoms, but its refreshing foliage is also popular. It is available as a fresh green leafy plant in summer and as an autumn foliage plant in autumn.

Being able to enjoy its changes throughout the year, feeling the passage of seasons, is one of the charms of Spiraea thunbergii ◎
