Edible Perennials - Zone 7 New England

The most appealing perennial edibles I’ve found so far, along with notes on each.

Plant		Type	Note
Greens
	Salad Burnet Sanguisorba minor	Species	Cucumber-flavored leaves, if you pick from center of plant
	Sea Kale Crambe maritima	Species	Flavor: Kale plus fish.
	Sorrel Rumex acetosa	Species	Young leaves taste like lemony baby spinach. Large leaves are bitter, but excellent cooked.
	Watercress Nasturtium officinale	Species	Peppery tasting salad green, can be cooked.
Vegetables
	Asparagus Asparagus officinalis	Species	Comes in purple!
	Chinese Yam Dioscorea batatas	Species	Tastes like potatoes
	Common Day Lily Hemerocallis fulva	Species	Harvest buds and fry them like okra. But then you will miss the flowers!
	Earthnut Pea Lathyrus tuberosus	Species	Another nutty tuber.
	Globe Artichoke Cynara cardunculus var. scolymus	Species	Prefer Fiesole or Violet De Provence (because purple!)
	Ground Nut Apios americana	Species	Nutty Potatoes.
	Hog Peanut Amphicarpaea bracteata	Species	Shelled peas taste similar to green beans. A lot of shelling for little beans though.
	Hosta undulata Hosta undulata	Species	Early spring shoots can be cooked like asparagus.
	Jerusalem artichoke Helianthus tuberosus	Species	Nutty potato flavor - but high in inulin which can cause digestive issues.
Ungrouped
