Evolvus, also known as Blue Daze or Hawaiian blue eyes, is a plant in the family Convolvulaceae. It is native to tropical and subtropical regions of the Americas, Asia, and Africa. Evolvus 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.
Growing and Caring For Blue Daze
Blue Daze is a hardy plant that is relatively easy to grow, provided it is grown in the right conditions. Ideal conditions for Blue Daze include full sun exposure and well-draining soil. It should receive at least six hours of direct sunlight daily. It tends to thrive in the heat and often is not available at Martin Garden Center until later in the spring.
Blue Daze prefers moderate moisture levels and it is essential not to overwater the plant. Overwatering can lead to root rot and other issues, so allowing the soil to dry out between waterings is paramount. With the right growing conditions, Blue Daze can thrive and produce a stunning display of blue flowers throughout summer.
Blue Daze is also easy to maintain. No dead-heading is necessary as the plant is self-cleaning. Furthermore, the plant is not susceptible to pests, making it ideal. Because of the fuzzy nature of the foliage, the plant tends to be deer resistant as well. Finally, the plant grows slowly so there is less need for pinching.
Evolvus Glomeratus
One of the most popular species of Blue Daze is Evolvus glomeratus. This plant is widely grown as a ground cover or border plant in gardens and landscapes, as well as a spiller in mixed containers. It has small, green leaves and produces clusters of small, trumpet-shaped blue flowers that bloom continuously throughout the growing season. Evolvus glomeratus is a low-maintenance plant that requires minimal care and is tolerant of heat and drought.
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.
Our Selection of Evolvus
At Martin Garden Center, we grow and carry 4″ Evolvus in the spring and summer including the varieties of Blue Daze and Blue My Mind, and Hawaiian Blue Eyes when available. We try to always have Evolvus 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 Evolvus hanging baskets. However, as we are dependent upon our vendors for Evolvus hanging baskets, we cannot provide exact dates when these hanging baskets will be available.
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
