| Author's Notes | It would be a bit of a challenge to grow "The Tower of Jewel" true to form in hardiness zone #5. Being a biennial it would take two years and it is a large plant. May well be worth the effort to add a very exotic element to the garden. They were impressive plants at the Chicago Botanic Garden. |
