Seville St. Augustine Grass

A Refined St. Augustine Variety

Seville is one of the older improved St. Augustine cultivars with a long history in Florida landscaping. It is prized for its fine-textured, soft blades and low growth profile, giving lawns a more manicured, refined appearance compared to the coarser Floratam. For homeowners who want the durability of St. Augustine with a smoother aesthetic, Seville has been a consistent option for decades.

Seville's finer leaf blades create a denser turf canopy at a lower height than most other St. Augustine varieties. This gives it an appearance closer to Zoysia in terms of texture, while still maintaining the broader characteristics and growth patterns of the St. Augustine family.

Characteristics

• Blade width: Finer than Floratam and CitraBlue, creating a softer feel underfoot
• Color: Medium green with good color intensity during the growing season
• Growth habit: Low, compact growth with shorter internodes between leaf blades
• Sun requirement: 4 to 6 hours of sunlight per day, though shade performance can be inconsistent
• Heat tolerance: Good — performs adequately in Jacksonville summers
• Cold tolerance: Weaker than Floratam and Palmetto — more susceptible to freeze damage
• Shade tolerance: Moderate but inconsistent — can thin in heavy shade despite being marketed for it
• Drought tolerance: Moderate — requires consistent irrigation during dry periods

Best Uses in Jacksonville

Seville works best in specific situations rather than as a general-purpose lawn grass for Jacksonville. Consider Seville for these scenarios.

• Protected courtyards and enclosed yards: Areas shielded from wind and cold exposure where Seville's fine texture creates an attractive, intimate landscape
• South-facing properties: Yards with good sun exposure and natural protection from north winds during winter cold events
• Accent areas: Small lawn sections where you want a finer texture to complement landscape beds, pavers, or outdoor living spaces
• Coastal properties: Homes near the beach or Intracoastal Waterway where the maritime influence moderates winter temperatures

Challenges in North Florida

Jacksonville sits at the northern edge of the St. Augustine grass belt, and Seville feels this boundary pressure more than hardier cultivars. Here are the specific challenges to be aware of.

• Cold damage: Jacksonville averages several nights below freezing each winter. While Floratam and Palmetto recover reliably, Seville can sustain more lasting damage during hard freeze events, particularly in low-lying areas prone to cold air pooling.
• Inconsistent shade performance: While Seville tolerates partial shade, its performance in lower light is less predictable than Palmetto's. Some installations perform well under trees while others thin out under seemingly similar conditions.
• Availability: Fewer North Florida sod farms carry Seville compared to Floratam, Palmetto, and CitraBlue. This can affect pricing and lead times for installation.

Maintenance Requirements

• Mowing height: 2.5 to 3.5 inches. Seville's low growth habit allows for a slightly shorter mowing height than Floratam, contributing to its manicured appearance.
• Mowing frequency: Every 7 to 10 days during the growing season. Seville's slower vertical growth means less frequent mowing.
• Watering: 1 inch per week during the growing season. Consistent irrigation is important because Seville's drought tolerance is only moderate.
• Fertilizing: 2 to 3 applications per year. Avoid heavy nitrogen applications that can increase thatch buildup in Seville's dense turf.
• Winter protection: If a hard freeze is forecast, water Seville thoroughly the day before. Moist soil retains heat better and can reduce freeze damage to roots and stolons.
