Persian Violet
Exacum affine · Gentianaceae
The Persian violet is a little blue wonder for the windowsill: a compact cushion of glossy leaves strewn with hundreds of star-shaped, blue-violet flowers with bright yellow stamens — plus a fine, sweet fragrance you would not expect from such a small plant. Think of it as a summer-long bloomer: weeks of abundant flowers rather than years of cultivation.

- Exacum affine
Botanically, Exacum affine really does belong to the gentian family — hence the German name Sommerenzian and the typical gentian blue of its flowers. Besides the blue-violet classics there are white and, more rarely, pink cultivars as well as double forms that look like miniature roses.
When buying we look for compact plants with plenty of closed buds among the open flowers. A good Persian violet then blooms for six to eight weeks with practically no pause — its bud reserve is its entire capital.
The ideal spot is bright and airy but out of harsh midday sun, at normal room temperatures between 18 and 22 degrees. In summer it also enjoys a sheltered place on the balcony or terrace; cold draughts and temperatures below 15 degrees, however, do not agree with this islander at all.
For watering the rule is: evenly moist, never wet, never bone dry. The fine root ball forgives neither — once dried out completely, the plant sheds buds and flowers. Watering from below and pouring off the excess is the safest method.
Regularly picking off the spent little stars pays off twice: it keeps the cushion tidy and encourages the plant to open its full bud reserve. After the main flush, a light trim can trigger a second, smaller wave of bloom with a bit of luck.
Good news for pet lovers: the Persian violet is considered non-toxic to cats, dogs and children. That makes it one of the safest fragrant flowering gifts — even for households where curious noses inspect everything.

Frequently asked
- How long does a Persian violet flower?
- A well-budded plant flowers for six to eight weeks, longer in a cool room with regular deadheading. After the main flush a light trim can bring a second wave; usually, though, the Persian violet is grown as a one-season plant.
- Is the Persian violet toxic to cats?
- No, Exacum affine is considered non-toxic to cats, dogs and people. That makes it one of the few fragrant flowering plants you can place in a cat household without worry.
- Why is my Persian violet dropping its buds?
- Bud drop is almost always stress: a root ball that dried out completely, cold draughts or an abrupt change of location. Even moisture and a fixed, bright spot without draughts let the remaining bud reserve open again.
- Does the Persian violet really smell?
- Yes, delicately but distinctly: a fine sweet fragrance most noticeable in the evening and in warm room air. For those sensitive to scent it is pleasantly subtle — it perfumes the windowsill, not the whole room.
