Tanashi azalea from Saitama Prefecture

Today we would like to introduce Tanashi azalea (Rhododendron L.) grown by Mr. Shimizu, Hanahan, Saitama Prefecture.

Tanashi azalea, propagated by crossing Rhododendron kaempferi, is named after the growing area of “TANASHI” city, Tokyo (now belongs to Nishi-tokyo City).

Because Tanashi azalea grows slowly, it takes four to five years before the next harvest. And, after harvesting, it needs to be placed in the greenhouse for about one and a half month to make flowers bloom. Due to this time-and-effort-consuming cultivation method, the number of grower is decreasing year by year.

Even under these circumstances, Mr. Shimizu steadily provides Tanashi azaleas in good volume, and from this year he standardizes them by length for easy use to buyers.

The harvesting period will end in the end of April. He also cultivates other cut branches such as cherry blossoms and snowballs (Viburnum opulus Roseum).

Why don’t you use this cut branches for spring flower arrangements?

Enjoy Japanese sweet pea

Sweet pea, Lathyrus odoratus, one of the legume family is a tendrils-climbing plant. Growers make it bloom beautifully and vertically straight. They make a lot of effort for the work, because it is an annual plants and naturally blooms in spring with twisting vines. This time, we will tell you about the cultivation of sweet pea.

Sweet pea has been cultivate in Japan for a long time since Meiji era(1868-1912) originally as an ornamental plant. Then, commercial cultivation of cut flowers began in the middle of the Taisho era(1912-1926). Around this time, Mr. Ishijiro Araki established the foundation of cultivation technique for sweet pea at Tamagawa glasshouse floriculture complex in Setagaya-ku, Tokyo.

How to grow sweet pea

Cultivation of sweet pea starts from raising seedlings. Seeds are taken care at low temperatures after soaked in warm water to promote germination. By adjusting this storage period, it is possible to shift the harvesting period from the beginning of winter. Planting will be carried out from late August to early September.

After planting, flower buds appear from the 10th nodes, but it is necessary to make the stock strong for long-term harvesting. By picking those early flower buds until it grows with the 14th nodes or more. It becomes possible to harvest about 20 stems from one strong stock.

Under the summer sun, the vine grows quickly to a height out of our reach with stems bent and vines twisted, when growers do not take enough care. To avoid that, growers lower each stem to a height of easy work for them and fix it to a net or pole. (Therefore, you couldn’t find slightly bent stems when this work is just done.)

In addition, the cultivation of sweet pea needs careful control of the amount of solar radiation and temperature. Since it is native to Sicily, Italy, the optimum temperature for growth is 15 degrees C, and the limit temperature of wilting is -3 degrees C. And it needs more than a few hours of sunshine consecutively a day. So, if the amount of solar radiation is insufficient or the temperature is too low, all buds could fall at once, and that could cause a sharp decrease in yield.

Furthermore, the stem shape changes depending on the amount of water absorbed. If growers supply too much water to the stock, the stem would grow faster, but it would become thinner and softer, and that could lead to a weak stem which can be bent easily, the internodes could be expanded, and flowers could be scattered on sight.

Thus, sweet pea id cultivated with a lot of work and careful management. So what is evaluated as “good quality”? Please let me tell you the tips to distinguish it.

  1. The stem is solid
  2. The internodes are clogged
  3. Large flowers and strong scent

To keep the vase life
Sweet pea is vulnerable to high temperatures and high humidity. Please note that in a hot and humid environment, Botrytis may increase and flowers may have dark spots or may fall off easily.

Keio Sakura.  the Japanese cherry blossom tree fascinates people with a lot of pale pink flowers and a dignified presence. From Yamagata prefecture where it still snows quietly, KeioSakura is announcing the beginning of spring.

“Mechanism to bloom flowers in winter”
KeioSakura starts to bloom by misunderstanding that spring has come when it is exposed to heat in the greenhouse after harvested from the field. Growers take advantage of this natural characteristic and can uninterruptedly continue shipping out from late December till Aprilby adjusting timings of harvests and treatments in the greenhouse. It gives a surprise to people all over Japan by the fact that blooming Keio-Sakura brings spring earlier from the snowy country like Yamagata prefecture.

Please pay attention to the following pointsWhen you take good care of KeioSakura, the flowers will not wither easily and can last long.

  1. When you put it in a vase, you should split the cut end of the branch verticallyThe surface area contacting with water increasesand that facilitates easy water uptake.
