Variety description

10 August 2026

The chrysanthemum variety "Radiant" is mentioned in specialized studies dedicated to photoperiodism. The plant exhibits sensitivity to day length, due to which it may form flower buds earlier than the scheduled cultivation period.

The variety name is often used as a descriptive epithet for other types of chrysanthemums, therefore it is necessary to distinguish the specific patented cultivar from plants with marketing names containing the word "radiant".
