Sea Holly is the one to pick if you are looking for a summery plant that can outlive even the hottest days of the year in full sun in your garden. Its indigo flowers last from July to September and will be a nice addition to your garden in stony or gravel areas. They are great for decoration and will also make nice flower arrangements for the cold season, as you can dry the flowers. They are loved both by gardeners and florists and will surely impress you too, once you decide to adopt it.
Eryngium planum “Jade Frost” is the first variegated Sea Holly plant, and they are a great addition to the garden, as they attract multiple pollinators that will benefit the garden overall. They grow up to 7,8-35 inches (20-90 cm) tall, and as they grow in a bush-like form, they get 8-26 inches (20-60 cm) in width as well. Sea Holly will bloom with pale, cream flowers in the beginning, only for them to turn indigo after a few days. You will also find it by the name of eryngo or spiny coriander, as the flowers cluster together in a spiny-like form. The leaves will remain at the bottom of the plant as it grows, and they have a green-cream coloration with pink margins as the temperature gets colder.
