Gardenias are a beautiful and fragrant plant that are popular among gardeners. They are known for their large, white flowers and glossy, dark green leaves. One of the most common questions people have about gardenias is how tall they can grow. In this article, we will explore the various factors that can influence the height of a gardenia plant.

Factors that Influence Gardenia Plant Height

There are several factors that can influence the height of a gardenia plant, including:


There are many different varieties of gardenias, each with their own growth habits. Some varieties may grow taller than others, so it is important to choose the right variety for your space.

Growing Conditions

The growing conditions of a gardenia plant can also impact its height. Gardenias prefer well-draining soil that is rich in organic matter. They also need regular watering and protection from direct sunlight.


Pruning can help control the height and shape of a gardenia plant. Regular pruning can encourage bushier growth and prevent the plant from becoming too tall.


The age of a gardenia plant can also play a role in its height. Younger plants may be shorter than older plants, which have had more time to grow.

Average Height of Gardenia Plants

On average, gardenia plants grow to be between 2 and 8 feet tall. The exact height will depend on the variety, growing conditions, pruning, and age of the plant.

Some varieties of gardenias, like the Gandharaj or Cape Jasmine, are known for their compact growth habit and may only reach heights of 2-3 feet. Other varieties, like the Veitchii or Kleim’s Hardy, can grow up to 6-8 feet tall with proper care.

Tips for Controlling Gardenia Plant Height

If you want to control the height of your gardenia plants, there are several tips to keep in mind:

  • Choose a variety that is suited to your space. If you have a small garden, look for compact varieties that won’t grow too tall.
  • Provide the right growing conditions, including well-draining soil and regular watering.
  • Prune regularly to prevent the plant from becoming too tall or leggy. Focus on removing dead or damaged branches and shaping the plant to your desired height and shape.
  • Consider using plant supports, like stakes or trellises, to help control the height and shape of your gardenia plants.


Can I grow gardenias indoors?

Yes, gardenias can be grown indoors as long as they have access to bright, indirect sunlight and are kept in a humid environment. They also prefer to be kept in temperatures between 60-70°F.

How often should I water my gardenia plants?

Gardenias prefer moist but well-draining soil, so it is important to water them regularly. Aim to keep the soil consistently moist but not waterlogged. In general, gardenias should be watered about once a week.

How do I prune my gardenia plant?

To prune a gardenia plant, start by removing any dead or damaged branches. Then, focus on shaping the plant to your desired height and shape. Make cuts at a 45-degree angle and avoid cutting too close to the main stem. It is best to prune gardenias in the spring after they have finished blooming.
