Beetroot juice. The common beetroot that is normally cooked and sliced or grated for salad is from the species Beta Vulgaris and the family Chenopodiaceae. Beetroot is commonly cooked, but the juice of raw beetroot contains a host of health benefits, and is classed as a super food in todays nutritional jargon.
Cook suggests incorporating plants like black-eyed Susan or Rudbeckia hirta, swamp milkweed (Asclepias incarnata, or even the Joe-pye weed (Eupatorium fistulosum). These plants will attract tiny pollinators, which also serve as food for the dragonflies.
Technically not native to the United States, Tropical Milkweed is widely popular in butterfly gardens. Growing as a naturalized perennial plant in the southern U.S., it can also be easily started from seeds in the northern U.S. and treated as an annual.
