Exacum Plant Stages of Growth

Updated: March 25, 2022

Exacum plant, also known as Persian violet, is a beautiful flowering plant that belongs to the Gentianaceae family. It is native to tropical regions of Africa and Asia and is a popular houseplant due to its attractive flowers and ease of care. Exacum plants require well-draining soil, moderate watering, and bright light to grow and thrive. In this article, we will discuss the different stages of growth of the Exacum plant.

Sprouting Stage

The first stage of growth in the Exacum plant begins when the seed germinates. The sprouting stage usually lasts for about 2-3 weeks. During this stage, the seedling develops its first set of leaves, which are usually small and delicate. It is crucial to keep the soil moist but not waterlogged during this stage as excessive moisture can cause damping off disease, which can kill the seedling.

Vegetative Stage

The vegetative stage in Exacum plants begins after the sprouting stage and lasts for several months. During this stage, the plant focuses on developing its foliage by producing more leaves and stems. The leaves are usually oval-shaped and have a rich green color. They are arranged opposite each other along the stem.

It is essential to provide adequate light during this stage to ensure healthy growth. The ideal temperature for vegetative growth is between 60-75°F (15-24°C). The Exacum plant also requires regular watering during this stage, but be careful not to overwater as it can cause root rot.

Flowering Stage

The flowering stage in Exacum plants usually begins after several months of vegetative growth. It is during this stage that the Exacum plant produces its beautiful flowers that come in shades of blue, purple, pink, and white. The flowers are star-shaped and have a delicate texture.

The Exacum plant requires bright but indirect light during the flowering stage. Direct sunlight can burn the flowers, and they may wilt prematurely. The ideal temperature during this stage is between 65-75°F (18-24°C). It is crucial to maintain consistent moisture levels during this stage to ensure the flowers last longer.

Dormancy Stage

The dormancy stage in Exacum plants usually occurs during the fall and winter months. At this time, the plant conserves energy and slows down its growth. The leaves may turn yellow and fall off, and the plant may appear lifeless.

During the dormancy period, it is essential to reduce watering and provide cooler temperatures (around 60°F or 15°C) to encourage the plant to enter dormancy fully. It is also a good time to fertilize the plant with a slow-release fertilizer to prepare it for the next growing season.


How often should I water my Exacum plant?

Exacum plants prefer moderate watering, which means that the soil should be kept moist but not waterlogged. Watering once every 7-10 days is usually sufficient.

Can I grow Exacum plants outdoors?

Exacum plants are tropical plants and require warm temperatures and high humidity to grow well. They can be grown outdoors in tropical regions but are best grown indoors as houseplants in other areas.

Why are my Exacum plant’s leaves turning yellow?

Yellowing leaves in Exacum plants can be a sign of overwatering or underwatering. Ensure that the soil is moist but not waterlogged and that the plant is not sitting in standing water.

How do I propagate my Exacum plant?

Exacum plants can be propagated through stem cuttings or by division. Take stem cuttings from healthy plants, and place them in a container with moist soil. Keep them in a warm, bright location until they develop roots. To divide the plant, carefully separate the root ball into two or more sections and plant each section in a new container with fresh soil.

In conclusion, the Exacum plant is an attractive houseplant that can add a touch of color and beauty to any indoor space. By understanding its different stages of growth and providing it with the right care, you can ensure that your Exacum plant thrives and produces beautiful flowers year after year.
