Perennial Vegetables I've Never Grown...Should I?

I have been re-reading Eric Toensmeier's Perennial Vegetables. In the process, I have been keeping a list of perennials that piqued my interest but with which I have never had any real experience.

• Ramps
• Lovage
• Skirret
• Chicory
• Scorzonera
• Turkish rocket
• Sea kale
• Good king henry
• Cinnamon vine
• Ostrich fern
• Chinese artichoke
• Giant Solomon's seal
• Bamboo
• Nettle

Have you ever grown any of these? How did it turn out? Would you recommend them to others? Why or why not?
