Lemongrass, with its refreshing citrus aroma and versatile culinary uses, is a popular herb among gardeners and cooking enthusiasts. If you are considering growing lemongrass in your garden or patio, it is essential to understand the different sizes that this plant can reach. By choosing the right lemongrass plant size for your needs, you can ensure successful growth and optimal utilization of this wonderful herb.

Understanding Lemongrass Growth Habit

Lemongrass (Cymbopogon citratus) is a tropical perennial grass that belongs to the Poaceae family. It has long, slender leaves and a bulbous base, which is the edible part of the plant. Lemongrass is native to Southeast Asia but is now cultivated in many parts of the world.

In its natural habitat, lemongrass can grow quite tall, reaching heights of up to 6 feet or more. However, when grown in containers or smaller spaces, its growth is usually restricted. The size of the lemongrass plant will depend on various factors such as the cultivar, growing conditions, and pruning practices.

Dwarf Varieties for Limited Spaces

For those with limited space or who prefer compact plants, dwarf varieties of lemongrass are an excellent choice. These varieties have been selectively bred to have a smaller size while still retaining the characteristic flavor and aroma of traditional lemongrass.

One popular dwarf variety is ‘East Indian Lemongrass’ (Cymbopogon flexuosus ‘East Indian’). This cultivar typically reaches a height of around 3 feet, making it suitable for container gardening or smaller gardens. Despite its smaller size, ‘East Indian Lemongrass’ still produces abundant foliage and has a strong lemony scent.

Another dwarf variety to consider is ‘Nana’ (Cymbopogon citratus ‘Nana’). This cultivar, also known as West Indian Lemongrass, grows to a height of approximately 2 feet. ‘Nana’ is well-suited for growing in pots or as a border plant in herb gardens. It is also a great option for those who want to bring lemongrass indoors during colder months.

Regular-Sized Lemongrass for Larger Gardens

If you have ample space in your garden and want to enjoy the full potential of lemongrass growth, regular-sized varieties are worth considering. These varieties can reach heights of 4 to 6 feet or even taller under ideal conditions.

One popular regular-sized variety is ‘Cochin’ (Cymbopogon citratus ‘Cochin’). This cultivar is known for its robust growth and large clumps of aromatic leaves. ‘Cochin’ requires more space due to its size but rewards gardeners with a bountiful harvest of flavorful lemongrass.

Another regular-sized variety is ‘Pai-Shen’ (Cymbopogon citratus ‘Pai-Shen’). This cultivar is commonly grown in Asian cuisine for its distinct lemon flavor. ‘Pai-Shen’ can grow up to 6 feet tall and requires adequate space to accommodate its size.

Pruning and Controlling Lemongrass Size

Regardless of the lemongrass variety you choose, proper pruning and maintenance practices can help control its size and promote healthy growth. Regular pruning not only keeps the plant within desired limits but also encourages the development of fresh, tender leaves.

To prune lemongrass, simply cut the leaves back to about 6 inches above the ground using sharp garden shears. This should be done in early spring or late winter before new growth appears. Pruning will stimulate the plant to produce new shoots and prevent it from becoming too leggy or overgrown.

If you are growing lemongrass in containers, it is important to choose a pot that allows for sufficient root growth. A pot with a diameter of at least 12 inches is recommended to accommodate the plant’s size and ensure healthy development.

Final Thoughts

Choosing the right lemongrass plant size is crucial for successful cultivation and utilization of this versatile herb. Whether you opt for dwarf varieties that are ideal for limited spaces or regular-sized varieties that thrive in larger gardens, there is a lemongrass cultivar to suit every need.

Consider your available space, desired harvest amount, and pruning capabilities when selecting the appropriate lemongrass size. With proper care and maintenance, your lemongrass plant will provide you with an abundant supply of fresh leaves and the delightful aroma of citrus for use in your culinary ventures.
