Bupleurum Flower

Native to central Asia and parts of southern Europe, the Bupleurum genus (pronounced boo-plur-rum) is made up of about 200 species of filler flowers and shrubbery. They are a part of the Apiaceae family and are an annual plant. Popular in China, this flowering plant is known as either Chai Hu or Thoroughwax (a name adopted around the world as well). They use the bupleurum mainly for medicinal uses, treating ailments like cough, flu, fatigue, fevers, colds and headaches.

Bupleurum is considered an easy plant to grow from seed form. On the contrast, it is considered very hard to grow from propagation. It thrives in both gardens and in containers when cared for properly and it looks best when used as a garden border or accent. When planting, give this flowering plant full light and well-draining soil. Space the bupleurum about a foot apart and fertilize it once a month. This is a good way to feed this flower extra nutrients for optimal growth. The bupleurum watering needs are considered to be average. Meaning, they need regular amounts of water to keep their soil moist, but they should not be overwatered. This flower blooms in summer, so planting seeds in the early springtime is best.

Once bupleurum is fully bloomed it should stand anywhere from 18-36 inches tall. The flowers are a yellowish-green color that sits in clusters of up to 12 florets. These clusters are then surrounded by large green, leaf-like petals. This filler flower appearance makes the bupleurum a popular choice by florists for vase arrangements and wedding bouquets.

To care for cut bupleurum in a vase, make sure to remove all greenery that will be sitting below the water line. Doing this will remove any additional bacteria that could become part of the water supply. Cut stems under water before placing in a vase and supply them with warm/room temperature water.
