White laceflower with firm stems

White laceflower (alias: bishop’s weed, binomial name: Ammi majus) growing at  Minami Bousou peninsula, located in the south area of Chiba prefecture.

White laceflower is native to the Mediterranean. So, it originally likes warm atmosphere. But when it is too warm, stems grow up so fast that they eventually become weak.

On the other hand, in cold atmosphere, stems grow up slowly, and they become firm. Now is a good season to use White laceflower as a cut flower thanks to its firm stems. But excessive coldness could kill White laceflower, because it doesn’t have cold-tolerance.

Growers of White laceflower must pay a lot of attention to temperature control.

Japanese growers’ craftmanship – high-quality Sweet Pea


Main stems of Sweet Pea usually grow up to as high as 7 meters and it is hard for growers to take care at the height, when growers use vertical cultivation system.

So growers apply the “Tsuru-Oroshi” technique for Sweet Pea. Literally, ”Tsuru” means “vine” and Oroshi means “bending down”.

Shoots of Sweet Pea are bended down parallelly using clothespins, and stems become lower enough for growers to take care.

In Japan, they do “Tsuru-Oroshi” by hand, carefully stem by stem, and that leads to high-quality Sweet Pea.
