Bougainvillea glabra is a vibrant flowering plant known for its colorful papery bracts that surround small, white true flowers.

Key facts

Detailed care guide

Bougainvillea is a vining plant known for its striking, paper-thin, colorful bracts. It loves strong sunlight and dry conditions.

Watering

Water it once the soil has dried all the way through. Overwatering can turn the leaves yellow and mushy, so be careful. Keeping it slightly on the dry side brings out deeper color in the bracts.

Light

It needs at least 6 hours of direct sun a day for the bracts to develop their beautiful color. Without enough light, the stems can grow leggy or the bracts may not color properly. It's best kept in the brightest spot you can offer.

Humidity

Bougainvillea likes low humidity. If humidity is too high, the leaves can become mushy or unhealthy. A well-ventilated spot is best.

Temperature

It grows well between 15–30°C. In very low temperatures the leaves can drop, and excessive heat can hinder growth. Keep the temperature within the ideal range.

A common first-timer mistake

Watering whenever the soil feels moist can easily lead to overwatering. Get into the habit of watering only once the soil has dried all the way through.

If you have pets

If pets eat bougainvillea, it can cause mild symptoms like vomiting or diarrhea. Keep it somewhere they can't reach or chew on.

Season by season

In spring and summer, give it plenty of sun, and water once the soil has dried completely. Once flowering starts, a phosphorus fertilizer every two weeks will make the bracts even more vibrant. In winter, cut back further on watering and avoid overly cold spots.

Common problems and fixes

Overwatering can turn the leaves yellow and cause them to drop, and the stems can rot and become mushy. On the other hand, severe dryness can cause the leaf tips to dry out and brown, so keep an eye on it. Without enough light, the stems grow leggy, so always keep it somewhere with plenty of light.

Repotting and propagation

Bougainvillea grows well in well-draining soil. Repot in spring once the roots feel crowded, and you can propagate it by taking cuttings from woody stems or new shoots. Handle the roots carefully so they aren't damaged.

Who it's a good fit for

This plant is great for anyone with a bright, warm space, or who tends to forget to water regularly. A spot with consistent strong sunlight and good airflow suits it well, and it's a great match for anyone comfortable keeping it on the drier side.
