When it comes to maintenance, Eryngium planum is a low-maintenance plant. It is relatively pest and disease-resistant, making it an excellent choice for beginner gardeners or those looking for a fuss-free addition to their garden. Deadheading the spent flowers will prolong the blooming period and keep the plant looking tidy.
Sea Holly's unique flower color distribution adds to its charm. The flowers have a unicolored appearance, with shades ranging from blue to dark blue-violet. This monochromatic coloration gives Eryngium planum a sophisticated and elegant look that stands out in any garden setting.
