Selecting the Best St. Augustine Grass Seed Varieties

St. Augustine grass (Stenotaphrum secundatum) is a popular warm-season turfgrass known for its lush, carpet-like appearance and exceptional heat and humidity tolerance. Choosing the right St. Augustine grass seed variety is a crucial step in achieving a beautiful and thriving lawn. With a variety of cultivars available, each possessing unique characteristics, it’s important to understand the key factors to consider when selecting the best St. Augustine grass seed varieties for your specific needs. In this comprehensive guide, we will explore the important criteria to keep in mind when making your selection.

1. Climate and Growing Zone Suitability

The first and foremost consideration when choosing a St. Augustine grass seed variety is its suitability for your climate and growing zone. St. Augustine grass is well-suited for warm and coastal regions, thriving in areas with hot summers and mild winters. However, different varieties have varying degrees of cold and drought tolerance. Research the specific growing requirements of each variety and choose one that aligns with the climate conditions of your region.

2. Sunlight and Shade Tolerance

St. Augustine grass varieties exhibit differing levels of tolerance to sunlight and shade. Some varieties, such as ‘Palmetto’ and ‘Seville,’ are known for their better shade tolerance, making them ideal choices for lawns with partial shade or areas that receive dappled sunlight. If your lawn experiences varying light conditions, opt for a variety that can handle shade without compromising its overall health and appearance.

3. Texture and Appearance

St. Augustine grass seed varieties can vary in blade width, color, and overall texture. ‘Floratam,’ for instance, features a coarser texture with broader blades, resulting in a denser appearance. ‘Bitter Blue’ offers finer blades and a vibrant blue-green hue, lending a more refined and visually pleasing look to your lawn. Consider the visual aesthetics you desire and select a variety that complements the overall style of your landscape.

4. Disease Resistance

Disease resistance is a crucial factor to consider, as it can greatly impact the long-term health and maintenance of your St. Augustine grass lawn. Some varieties exhibit higher resistance to common lawn diseases, such as gray leaf spot and brown patch. Research the disease resistance characteristics of different varieties in your region to minimize the risk of disease-related issues in the future.

5. Wear and Traffic Tolerance

If your lawn is subject to heavy foot traffic from children, pets, or frequent social gatherings, selecting a St. Augustine grass seed variety with good wear and traffic tolerance is essential. Varieties like ‘Floratam’ and ‘Palmetto’ are known for their ability to withstand moderate to heavy use, making them suitable choices for active outdoor spaces.

6. Salt Tolerance

For homeowners in coastal regions or areas with high salt content in the soil, salt tolerance is a critical consideration. Some St. Augustine grass varieties, such as ‘Seville,’ possess better salt tolerance, allowing them to thrive in environments where soil salinity may be an issue.

7. Maintenance Requirements

Different St. Augustine grass varieties may have varying maintenance needs. Some varieties require more frequent mowing and fertilization, while others are known for their lower maintenance requirements. Consider your willingness and ability to commit to the necessary upkeep, including mowing, watering, and fertilizing, when choosing a variety.

8. Local Availability

It’s important to select St. Augustine grass seed varieties that are readily available in your local area. Working with local nurseries, garden centers, or landscaping professionals can help you identify the varieties that are well-suited to your region’s conditions and are readily accessible for purchase.

9. Personal Preferences

Ultimately, your personal preferences and priorities play a significant role in choosing the best St. Augustine grass seed variety. Consider factors such as your desired lawn appearance, color preferences, and specific lawn use to find a variety that aligns with your vision for your outdoor space.


Selecting the best st augustine seed variety requires careful consideration of climate suitability, sunlight and shade tolerance, texture, disease resistance, wear tolerance, salt tolerance, maintenance requirements, local availability, and personal preferences. By thoroughly researching and evaluating these factors, you can choose a St. Augustine grass variety that not only thrives in your specific growing conditions but also enhances the beauty and functionality of your lawn. Remember that each variety has its own unique strengths and characteristics, so take the time to make an informed decision that aligns with your landscaping goals and long-term vision for your outdoor environment.
