Fun facts
- It was introduced to Europe in 1932 by French botanist Robert Blossfeld, for whom the species is named.
- Flowering is triggered by short days: growers give plants about 14 hours of darkness daily for several weeks to set buds.
- It is one of the best-selling potted plants in the world, especially popular around Christmas and Chinese New Year.
- After blooming, trimming spent flower heads and giving short days can coax the plant to rebloom year after year.
