NEW! Corine Light Blue Trachelium, Throatwort, Trachelium Caeruleum, TR6020P
Trachelium caeruleum
Corine Light Blue Trachelium (Trachelium caeruleum), also known as Throatwort, is a florist’s favorite for its striking dome-shaped flower heads packed with hundreds of tiny starry blooms. The Corine series is prized for uniform growth, strong stems, and long-lasting color, making it a top choice both in the garden and for cutting. The light blue form offers a soft, airy hue that blends beautifully in arrangements, adding texture and volume.
This variety is exceptionally well-branched and produces generous clusters of blooms on sturdy, upright stems. In the garden, it provides soft, cloud-like mounds of color. In the vase, it is cherished as a filler flower, lasting 7–10 days fresh cut, and pairing beautifully with roses, lisianthus, sunflowers, and snapdragons. Its light blue shade works well in wedding arrangements, cottage-style bouquets, or modern mixed designs.
