A blue plant that is also drought tolerant and a pollinator magnet is a true treasure. Sea holly (Eryngium planum) has all these features and more, making it a must-have for border gardens.

2. Verbena bonariensis Another one of those drought-tolerant plants we love, verbena bonariensis make for beautiful garden borders, requiring only the lightest of deadheading sessions come the autumn.

A clumping liriope such as 'Big Blue' would make a more easily controlled border than one that spreads by runners. You also could use stones rather than plants as a border.

The 2023 Louisiana Super Plant selection for the summer is a dwarf morning glory known as evolvulus, and there are two great cultivars the AgCenter is recommending: Blue My Mind and Blue Daze.
