Red Valerian
Centranthus ruber · Caprifoliaceae (Geißblattgewächse, früher Baldriangewächse)
With its airy clustered panicles in carmine, pink and white, red valerian lends any bouquet a summery, Mediterranean lightness. It is one of the more unusual cut flowers, which is exactly why we love it for natural, romantic arrangements in our workshop. Sourced fresh at the Rhein-Maas auction, it lasts noticeably longer than such a delicate bloom would suggest.

In trade and garden you mainly encounter three colour forms: the deep carmine Centranthus ruber „Coccineus“, the pure white Centranthus ruber „Albus“, and soft salmon-pink shades. Botanically these are the same species, only the flower colour varies markedly. Each tiny bloom carries a fine spur, and en masse they form the characteristic dome-shaped flower heads on long, lightly branched stems.
In floristry we value red valerian as a filler and structural element. It loosens up dense bouquets, adds height and a wild romantic character without ever dominating. Its airy silhouette comes into its own in summery meadow bouquets, natural-style bridal arrangements and Mediterranean-inspired designs. The light, sweet fragrance is a pleasant bonus.
Quality depends on the right cutting stage: stems on which some florets have already opened while others remain in bud last longest in the vase and keep developing. When buying we look for firm green stems and panicles free of brown spots. Thanks to A1 quality and short routes via the auction, our red valerian achieves a vase life that usually exceeds the industry-standard seven days.
Red valerian combines beautifully with other summer blooms. Paired with roses, cosmos, yarrow, meadow herbs and grasses it creates a loose, natural look. In monochrome bouquets the vivid carmine sets strong accents, while the white form blends elegantly into delicate pastel arrangements. Anyone who likes things wild and unaffected is well served by it.
Care
- 01Cut stems at an angle before placing them in water, ideally under water so no air enters the channels.
- 02Remove lower leaves that would otherwise sit in the water and rot.
- 03Use a clean vase and fresh, lukewarm water; a dash of flower food extends longevity.
- 04Change the water every two to three days and trim the stem ends each time.
- 05Choose a cool spot out of direct sun, away from heating, fruit bowls and draughts.
- 06Pluck out spent individual florets regularly to keep the panicle looking fresh.
Frequently asked
