Princess Deep Blue Exacum

Princess Deep Blue is a compact, mounded selection of Exacum affine grown for its long-lasting, fragrant blue flowers and glossy green leaves. The producer lists a mature height of 4–6 inches and a spread of 7–8 inches, making it suitable for a small pot, tabletop display, or the front of a mixed container. ## Display and growing conditions Place the plant where its flowers can be enjoyed up close. PanAmerican Seed lists a sales season from March through October and notes the sweet fragrance of its flowers. The species profile from Singapore’s [National Parks Board](https://www.nparks.gov.sg/florafaunaweb/flora/4/0/4091) describes Exacum affine as an evergreen herb with blue to purple flowers, moderate water needs, and a preference for well-drained soil in semi-shade to full shade. The [Princess Deep Blue product page](https://www.panamseed.com/Products/026301189000653/exacum-princess-deep-blue/) provides the selection’s size and bloom information. ## Container care Choose a pot with drainage and water when the surface begins to dry, keeping the mix evenly moist without leaving the roots standing in water. Give the plant enough light for flowering while protecting it from excessive heat. ## Maintenance Remove faded flowers and yellowing leaves to keep the small mound tidy. Replace the plant when flowering declines or stems become sparse.
