what lagerstroemia ground covering are good

Lagerstroemia, commonly known as crape myrtle, are prized for their vibrant summer blooms and attractive bark. While they're typically grown as trees or shrubs, there's growing interest in finding ground cover varieties. However, true groundcover Lagerstroemias are limited. This article explores options for achieving a groundcover effect with crape myrtles and what to consider.

Understanding the Limitations of Crape Myrtle as Groundcover

Before diving into options, it's crucial to understand that no Lagerstroemia variety is naturally a low-growing, spreading groundcover. Most are upright, multi-stemmed shrubs or trees. The desire for a crape myrtle groundcover stems from the beautiful flowers and overall aesthetic.

To achieve a groundcover effect, you must select certain types and employ specific planting and pruning techniques. We'll look at that below.

Approaches to Create a Crape Myrtle Groundcover Effect

There are two main ways to create the illusion of a crape myrtle ground cover:

1. Using Dwarf or Low-Growing Cultivars:

Certain crape myrtle cultivars exhibit more compact growth habits than others. These are your best bet for achieving a denser, lower-profile planting. Look for cultivars described as "dwarf," "compact," or "low-growing." These are typically smaller than standard crape myrtles, and some are even suitable for containers. These don't spread like a true groundcover but, when planted closely, offer a more unified look.

Examples (availability varies by region): Check with local nurseries for cultivars suited to your climate. Many nurseries are increasingly offering smaller cultivars specifically marketed for landscaping. Search for cultivars online using your area. Descriptions often highlight height and spread.

2. Strategic Planting and Pruning of Standard Varieties:

Even standard-sized crape myrtles can be used to create a groundcover effect with careful planning and consistent pruning. This approach requires more effort.

Close Planting: Plant multiple crape myrtles closely together. They'll eventually fill in, creating a more continuous line or mass planting.
Regular Pruning: Frequent, light pruning encourages bushier growth. This method needs consistent commitment. Pinch back new shoots regularly to encourage branching and keep the plants low and full. Avoid hard pruning, as this might stimulate tall, leggy growth.

Choosing the Right Crape Myrtle for Your Climate

Crape myrtle hardiness varies significantly. Some varieties thrive in USDA Plant Hardiness Zones 7-9, while others extend their range beyond those zones. Before purchasing any crape myrtle, research which varieties are well-suited to your specific climate. This ensures optimal growth and prevents disappointment. Your local nursery or agricultural extension service can provide valuable recommendations.

Other Considerations

Soil: Crape myrtles prefer well-drained soil. Poor drainage can lead to root rot.
Sunlight: Most crape myrtles need at least six hours of direct sunlight daily.
Maintenance: Regular watering, fertilization, and pruning are essential for healthy growth, regardless of the cultivar.

Conclusion: A Crape Myrtle Groundcover is Possible

While a true groundcover crape myrtle doesn't exist, a similar effect can be achieved by selecting dwarf varieties or carefully managing standard cultivars through close planting and consistent pruning. Be sure to select a variety suitable for your local climate and soil conditions. Remember that even with dwarf cultivars, achieving a truly dense groundcover might take several years. However, the stunning blooms will make the wait worthwhile.
