Blue Daze Is an Ideal Ground Cover

If you're looking for a ground cover that delivers color, toughness, and ease of care, look no further than Blue Daze (Evolvulus glomeratus). Native to Brazil and perfectly suited for Southern U.S. climates, this hardy, sprawling plant is a favorite among gardeners seeking both beauty and practicality. Its vivid blue blooms, trailing habit, and heat tolerance make it a go-to choice for everything from formal borders to sunny slopes.

Let’s explore 8 reasons why Blue Daze earns its reputation as an ideal ground cover.

Low-Growing Habit

One of the most attractive features of Blue Daze is its naturally low-growing structure. It tops out at 6 to 12 inches in height, staying compact and tidy without requiring constant trimming. This makes it an excellent choice for garden edges, walkways, or the front of flower beds, where taller plants might obscure visibility or overtake space.

Because it hugs the ground and forms a dense mat of foliage, Blue Daze keeps your garden looking neat while enhancing visibility of hardscape features like pavers or stepping stones. It’s especially popular for use along paths, patios, and rock gardens where you want color without height.

Spreading Nature Without the Invasion

Many ground covers tend to spread aggressively and take over surrounding plantings, but Blue Daze offers the perfect balance. Its spreading habit fills in gaps efficiently, yet it stays where you want it. Unlike invasive groundcovers like mint or ivy, Blue Daze has a well-behaved growth pattern that makes it easy to manage and shape.

Within a single season, it can cover large areas of bare soil, making it perfect for slopes, retaining walls, or patches of poor-quality ground where little else grows. And because it spreads via trailing stems rather than underground rhizomes, it won’t sneak into areas where it’s not welcome.

Vivid Blue Flowers That Pop

Perhaps the most eye-catching feature of Blue Daze is, of course, its sky-blue flowers. True blue is a rare color in the plant world, and Blue Daze delivers it in abundance. The 1-inch blooms contrast beautifully against the plant’s silvery-green foliage and add a calming, coastal feel to any landscape.

These flowers open during the day and close at night, creating a rhythmic, ever-changing display. They also attract pollinators like bees and butterflies, adding ecological value to their aesthetic appeal. Whether you’re planting them in beds, baskets, or along a sunny slope, the continuous splash of blue brings texture and vibrance all season long.

Tolerates Light Foot Traffic

Unlike many flowering ground covers that are too delicate to handle any pressure, Blue Daze can tolerate occasional foot traffic. While it’s not intended for high-use paths like turfgrass, it does well in areas where people might walk now and then—for instance, between stepping stones or along the edge of a patio.

Its flexible stems and dense growth allow it to bounce back quickly from minor damage, making it a good choice for shared spaces where kids or pets may occasionally stray from the beaten path. Just give it a little room to grow, and it’ll reward you with durability and grace.

Heat and Drought Tolerant

Blue Daze is built for the Southern climate. This plant thrives in hot, sunny environments, tolerating temperatures well into the 90s and 100s without losing vigor. Once established, it is remarkably drought tolerant, making it ideal for water-wise landscapes and xeriscaping.

Its tolerance for sandy, well-drained soils makes it especially useful in coastal regions and areas with poor soil quality. If your garden gets full sun and your summers are scorching, Blue Daze will thrive where other plants wilt.

Low Maintenance, High Reward

Busy gardeners rejoice: Blue Daze is about as low maintenance as it gets. It requires no deadheading to keep blooming, and its compact growth usually doesn’t need trimming unless you want to shape it. Pests and diseases rarely pose a problem, and even deer tend to leave it alone.

Fertilization is minimal—just an occasional dose of a balanced, slow-release fertilizer in early spring is enough to keep it happy. It’s the kind of plant you can plant and forget—until it surprises you with another flush of beautiful blue blooms.

Long Blooming Season

From late spring through the first frost, Blue Daze stays in bloom—nearly nonstop. While many ground covers offer foliage or color only in select seasons, Blue Daze holds strong through the entire growing season, making it a great investment for consistent curb appeal.

It’s especially valuable in hot climates where traditional flowering plants may go dormant during peak summer heat. Blue Daze just keeps going, even in the height of July and August, when other blooms fade.

Natural Weed Suppression

Another major benefit of Blue Daze is its ability to suppress weeds naturally. As it spreads, its dense foliage covers the soil surface, blocking sunlight and reducing space for weed seeds to germinate. This not only improves the look of your beds but also saves you time and effort pulling unwanted plants.

Because it doesn’t require mulch to fill in gaps, it also provides a cleaner, more uniform appearance compared to beds covered in bark or gravel. The less exposed soil you have, the fewer weeds you’ll battle.

Blue Daze is A Top Notch Ground Cover

Blue Daze checks all the boxes: it’s tough, beautiful, low-maintenance, and practical. Whether you’re trying to reduce lawn space, stabilize a slope, brighten up a border, or fill in a hot, sunny bed, this versatile ground cover makes the job easy. With its year-round color, drought resilience, and gentle spreading habit, Blue Daze brings both beauty and function to any Southern garden. If you’re looking for a ground cover that works as hard as it looks good, Blue Daze just might be the perfect fit.
