There is no right way to curate the perfect summer border. It all comes down to personal taste and the look you want to achieve in your backyard. But, if there's one unique bloom to add to your flower display, it's eryngium. These unique blue-purple flowers offer structure in flower beds during summer and sculptural seed heads for fall and winter interest.
Also known as sea holly, eryngium is native to the UK and is a perfect addition to classic cottage gardens with a hue that softens borders while offering strong leaf structure. Despite its name, sea holly is actually not related to holly plants but is a member of the Apiaceae (carrot) family. It's an architectural plant that blooms from July to September before its beautiful seed heads appear in fall.
