Classification of Trachelium caeruleum varieties: excellent floral material for flower arranging and cut flowers
Flowers that are not flowers, mist that is not mist. It comes at midnight, leaves at dawn. It comes like a spring dream that does not last long, and departs like morning clouds with no place to be found. Just as described in the poem, Trachelium caeruleum is ethereal and enchanting, and is deeply loved by people.

1. The "Devotion" series of Trachelium caeruleum
Trachelium caeruleum has long been favored by floral designers, and now there are brand-new potted varieties and border-type varieties suitable for cultivation in small environments, namely the "Devotion" series of Trachelium caeruleum.
The Devotion series includes three flower color varieties: blue, purple, and white.
The Devotion series can grow to 75——90 cm tall, with elegant leaf shapes, umbellate inflorescences, surrounded by smaller partial umbels or accompanying inflorescences.
2. The "Lake" series of Trachelium caeruleum
The Lake series is also a variety later developed by people that is suitable for cut flowers.
Lake Trachelium caeruleum is a long-day flowering plant, but the two "Forest Lake" color varieties can flower under short-day conditions.
The Lake series of Trachelium caeruleum can be subdivided into: Island Lake (pink)
Forest Lake: Blue Forest Lake (medium blue), White Forest Lake (pure white)
White Lake Michigan (pure white)
Improved versions: Improved Lake Powell (white), Improved Sunset Lake (wine red)
