Garden Peony
Paeonia lactiflora
Ants on peony buds are not pests — they harvest sweet nectar from the bud sheath and may help open the flowers (the famous "peony-ant mutualism").
How to care for garden peony
Plant eyes (buds on the tuber) no more than 1-2 inches below the soil surface — planted too deep, peonies refuse to bloom for years. Don't disturb once established; peonies live 50-100 years in the same spot.
