Royal Dane Deep Blue Exacum

Royal Dane Deep Blue is a compact Exacum affine grown for clusters of long-lasting, sweetly fragrant blue-violet flowers. Its small habit suits a bright indoor pot or a sheltered seasonal display where the blooms can be enjoyed close up. ## Garden use The Royal Dane series selection is listed at about 4–6 inches tall and 7–8 inches wide, making it useful for a tabletop container or as a close-view accent. The blue-purple flowers have bright yellow centers and appear over an extended spring-to-autumn production season. The [Ball product profile](https://info.ballseed.com/WEBTRACKPLANTINFO.ASPX?PHID=026300943000653&env=P) identifies the selection as Persian violet and notes its sweet fragrance. ## Growing conditions Give it bright filtered light or partial shade; avoid hot, direct midday sun. Use a moisture-retentive but freely draining potting mix and water when the surface begins to dry. North Carolina State Extension describes the species as a warm-climate plant with blue-to-purple spring and summer flowers and moist, well-drained soil; the [plant profile](https://plants.ces.ncsu.edu/plants/exacum-affine/common-name/arabian-gentian/) is useful for general culture. ## Maintenance Keep the mix evenly moist without leaving the pot standing in water. Remove spent flowers to keep the plant tidy, and protect it from cold drafts. Treat it as a seasonal flowering plant in cool climates.
