Also called Blue Daze, evolvulus is a charming groundcover that offers true-blue flowers, a rarity in the gardening world. Those sky-blue flowers look great against its silvery-green foliage. It blooms nonstop, making it valuable for edging garden beds and borders or spilling over the side of a container garden. One quality that makes evolvulus such a good choice for Florida gardens is that it’s delightfully drought tolerant. Once established it rarely needs watering outside of natural rainfall. If evolvulus has a downside, it’s that its blooms are glorious in the morning, but usually close up by noon – so be sure to plant it where you’ll enjoy it during the morning hours. Evolvulus typically grows about 6 inches tall and 12 to 18 inches wide.

Grow evolvulus in full sun or part shade and well-drained soil. Fertilizing it helps encourage best bloom display. It’s reliably perennial in Central and South Florida; in North Florida, it behaves more like an annual, especially in colder-than-average winters.
