Meaning of Trachelium

Its very genus name comes from the Greek word “trachelos” which means neck, Trachelium means rough throat. This also explains the common name throatwort. “Wort” is an old word with origins in England or Germany and means plant root. It was nicknamed Throatwort because it was used in ancient times for the treatment of neck or throat sores, but it was a flower that also used to symbolize unnoticed or neglected beauty.

Trachelium care

Growing Trachelium in pots and gardens is quite easy. It is best to sow the seeds during late winter. By simply putting the seed on the surface of the soil in pots or containers, they will germinate successfully in a matter of weeks.Throatwort Trachelium Garden flowers Throatwort Trachelium

Select straight, well-branched stems that have about half of their florets open. If stems are harvested too quickly, or sold too early, their flower clusters may not open properly. So, make sure any stems you use have lush flowering heads and unmarked, green foliage.

When processing, strip foliage that falls below the water line. Recut the stems about 2.5 cm at an angle (45-degrees) and hydrate them in room temperature water mixed with a commercial floral preservative (with sugar) for at least two hours before storage or use in floral work. Although not required, stems can be recut under running water or in a bowl of clean water. Cutting under water may reduce the risk of air pockets forming at the stems’ base and allows the flowers to absorb water right away.

Stems can be stored at 36–39ºF (2.2–3.9ºC) for a couple of days.

Trachelium is a heavy water drinker, so always ensure the stems are well hydrated.

Trachelium is suitable for air drying. However, their florets tend to lose much of their color when dried.
