Royal Dane White Exacum

Royal Dane White exacum (Exacum affine) is a compact, seasonal flowering plant grown for small, fragrant blooms and a neat container scale. PanAmerican Seed lists this white-flowered Royal Dane selection at 4–6 inches tall and 7–8 inches wide, with flowering offered from early spring through autumn. ## Placement Use it in a small pot, mixed container, or sheltered seasonal display. The grower lists sun exposure for production, while UF/IFAS describes Persian violet as suited to part sun or part shade in the landscape; protect plants from harsh afternoon heat and cold. ## Soil and Water Choose a light, well-drained potting mix. UF/IFAS recommends moderate watering and notes that the plant is tender to cold, so treat it as a seasonal annual outdoors in climates with frost. Keep the mix evenly moist without leaving the pot standing in water. ## Flowers The Royal Dane White product is a white selection of the species. Royal Dane flowers are described by the breeder as long-lasting and sweetly fragrant.

Discard or protect it before freezing weather; it is not a cold-hardy perennial.
