Suitability for cutting — ornamental allium

Allium L.

Ornamental allium is valued in floristry for its long vase life (10–20 days) and sturdy, leafless scapes. The main specifics of the crop involve a pungent aroma that requires rinsing with water and the need for careful selection of the harvest stage.

In the reference 21 varieties crop Ornamental Allium, where this is mentioned in the description.

To ensure maximum decorative appeal, harvesting is carried out when 1/3 to 1/2 of the florets in the inflorescence are open, while for use in dried bouquets, the inflorescences are allowed to open fully. The crop’s long scapes are ideal for vertical arrangements and tall vases.

When working with Allium, it is important to consider the presence of sulfur-containing compounds that create a specific odor when the stem is cut, the intensity of which can be reduced by rinsing in cold water. Due to the risk of aroma intensification in heat, it is recommended to use the crop with caution for decorating enclosed spaces with high temperatures.

The vase life of cut inflorescences is up to three weeks. To maintain quality, it is recommended to use preservatives in the water and regularly trim the stems at an angle. If the globe-shaped inflorescence loses its shape, florists apply a technique of gentle fluffing while held upside down.
