Cultivation
Exacum L.
Exacum is grown as an annual potted crop with a short production cycle, valued for its self-branching habit and compact, globular shape.
In the reference 5 varieties crop Persian violet, where this is mentioned in the description.
In commercial floriculture, Exacum is used as a quick-turnover annual with a life cycle limited to a single sales season. The plant possesses a natural branching ability, which allows it to form a dense canopy without pinching, making it well-suited for marketing in 10–15 cm pots.
Flowering initiation in this crop depends on the total light integral and plant size, rather than the photoperiod. Exacum is sensitive to iron and manganese deficiency, as well as to excess substrate moisture, which makes it susceptible to gray mold (Botrytis cinerea) when water stagnates on the leaves.
