Cynara cardunculus

Cardoon. Big ol artichoke cousin that has amazing architectural bold, silver leaves that are up to 30″ long and half as wide. Forms a large rosette (4′ across) initially then the stem extends rising to 4′ tall bearing huge rich, violet blue flowers that are up to 5″ across held in a cylindrical calyx. Open call to all pollinators. Blooms begin in the second year in May and repeat to August. Full sun, rich, well drained soil with light summer water. Give it room to spread out horizontally because it inevitably will. Light deer resistance.  Beautiful perennial in all of its parts. Lifespan (3-5 years )  on average.
