I have no experience with that plant, but I’ll try anything once.LOL
Convallaria majalis, a rhizome with dainty white flowers and entirely poisonous, is a cool climate plant. It thrives in USDA Zones 2-5, and struggles in Zone 7.
Pieris japonica is an evergreen shrub with cascading white flowers. Native to Japan, Taiwan and eastern China, recommended USDA Zones 4-8, with light shade needed warmer climates. This is also a toxic specimen, leaves and nectar are harmful when ingested.
