Evolvulus, also known as Blue Daze, is a plant in the family Convolvulaceae. It is native to tropical and subtropical regions of the Americas, Asia, and Africa. Evolvulus plants are grown for their attractive gray foliage and delicate blue flowers that bloom throughout the year in warm climates. Blue Daze typically grows to a height of 6 to 12 inches, forming a low, spreading mound. Its compact and trailing habit makes it ideal for ground cover, hanging baskets, or as an edging plant in garden beds.
Our Selection of Blue Daze
At Martin Garden Center, we grow and carry 4″ Evolvulus in the Spring and Summer. Our three most popular varieties are Blue My Mind, Hawaiian Blue Eyes, and Beach Bum Blue.
We try to always have Evolvulus stocked, though in the Spring, this plant may be temporarily out of stock for a week or two depending on growing schedules and demand. We also carry Blue Daze hanging baskets. However, as we are dependent upon our vendors for hanging baskets, we cannot provide exact dates when these hanging baskets will be available.
Growing and Caring For Blue Daze
Blue Daze is a hardy plant that is relatively easy to grow when given the conditions it prefers. Full sun is essential for the best performance, with at least six hours of direct sunlight each day, although even more sun often results in heavier blooming and denser growth. Well-draining soil is equally important, as Blue Daze does not tolerate wet feet or poorly drained planting sites. Once established, it thrives in hot, sunny conditions that cause many other flowering plants to struggle. Its exceptional heat tolerance makes it particularly valuable in Southern gardens, where it continues to perform through the hottest parts of Summer.
Blue Daze prefers moderate moisture levels and benefits from a consistent watering schedule while becoming established. However, it is important not to overwater, as excessive moisture can quickly lead to root rot and decline. Allowing the soil surface to dry slightly between waterings encourages a healthy root system and helps prevent common moisture-related problems. Once established, Blue Daze demonstrates good drought tolerance and can handle short dry periods better than many annual flowering plants. During extended stretches of hot, dry weather, occasional deep watering will help maintain vigorous growth and continuous flowering. With the right balance of sunlight, drainage, and moisture, Blue Daze can produce an impressive display of vibrant blue flowers from late Spring until frost.
Blue Daze is also exceptionally easy to maintain, making it an excellent choice for gardeners seeking reliable color with minimal effort. No deadheading is necessary because the plant is self-cleaning and naturally sheds spent blooms as new flowers emerge. Unlike many flowering annuals, it rarely requires regular grooming to keep it looking attractive throughout the growing season. The fuzzy, silvery-green foliage is not only ornamental but also helps deter deer, which tend to avoid plants with hairy or textured leaves. Blue Daze is generally resistant to most insect pests and diseases, further reducing maintenance requirements. Its naturally compact growth habit and relatively slow growth rate mean there is little need for pinching or pruning, allowing it to maintain a tidy, mounded appearance with very little intervention.
Uses in the Garden
Blue Daze is most commonly used as a trailing plant in mixed baskets, but it can also be used as a ground cover. Its dense, low-growing foliage forms a beautiful mat of greenery (or gray-ery…) that helps to suppress weeds and retain soil moisture. Blue Daze is also an excellent choice for attracting pollinators, as its blue flowers provide a valuable source of nectar. Moreover, the plant’s ability to thrive in hot, dry conditions makes it an ideal choice for xeriscaping, where water conservation is a priority.
Frequently Asked Questions
Will Blue Daze Survive A Freeze?
Blue Daze is sensitive to freezing temperatures. While it thrives in full sun and warm climates, exposure to frost or freezing conditions can damage or kill the plant. In the Upstate, we treat Blue Daze as an annual.
Do Deer and Rabbits Eat Blue Daze?
Blue Daze is generally considered deer-resistant due to its bitter taste and potentially unpalatable nature. As for rabbits, they are unlikely to consume Blue Daze, as it is not among their preferred food choices.
