Silver Sea Holly is a fantastic variation of eryngium planum. It has a silver colour rather then your commonly seen blue. Butterflies are highly attracted to sea holly and will bring live and colour to your garden. Silver sea holly works best along side other eryngium planum on borders, with the correct colour choice these can make fantastic combinations. They can tolerate high heat and light droughts. Silver Sea Holly has a irregular germination time and can take between a week and three months.
