Key facts

Care Guide

Detailed care guide

Lisianthus is a flowering plant with elegant, rose-like petals in a variety of beautiful colors. It's on the harder side to care for, so it needs some careful attention.

Watering

It's best to water when the soil surface dries out. Overwatering turns the leaves yellow and mushy, so be careful. Dryness can also dry out and brown the leaf tips.

Light

It needs plenty of bright direct sun to grow healthy. If light is lacking, the stems can grow leggy, so keep it as close to a window as possible.

Humidity

Normal indoor humidity is fine. You don't need to raise humidity specially, but avoid excessive dryness.

Temperature

Keep it at 15–25°C. If the temperature is too low or too high, the flowers can wilt or growth can be hindered.

A common first-timer mistake

The most common mistake is watering too often. Watering only after the soil surface has fully dried out helps prevent overwatering.

If you have pets

Lisianthus is not known to be toxic to pets. That said, any plant eaten in large amounts can cause an upset stomach, so move it if your pet chews on it habitually.

Through the Seasons

Lisianthus needs bright light year-round, across spring, summer, fall, and winter alike. In spring and fall, temperature and humidity tend to be moderate, making care fairly easy. In summer, watch that the temperature doesn't climb too high, and in winter, keep it indoors so it doesn't drop below 15°C.

Common Problems and Fixes

Yellow, mushy leaves are often a sign of watering too often. Conversely, dry or browning leaf tips signal the soil has dried out too much. If the stems grow weak and long, it's short on light, so move it somewhere brighter.

Repotting and Propagation

Using a well-draining soil mix when planting is important. Repot once the roots feel crowded or the old soil no longer drains well. Propagation and detailed soil-mixing methods can get complicated, so it's best to focus on the basics of care.

Who It's Good For

Lisianthus is a great recommendation for anyone who enjoys caring for plants in detail, or who wants to savor the beauty of its flowers for a long time. It suits anyone willing to put in time and attention. It's best suited to someone who will observe it carefully in a bright, mild environment.
