Eryngium, also known as Sea Holly, is available from June to October. It has a distinctive spiky form with violet blue and green colored bracts that often have a silver or metallic cast. As a medium sized flower, it adds interest to designs when used in moderation and sells for $9 per bunch. Floral picks are artificial stems used to attach fresh or dried flowers to arrangements and can be made of metal, wood, or wire. Pick machines are used to attach picks to flower stems to make it easier to insert them into foam for arrangements.
