Major health organizations and poison control centers have given Persicaria odorata a clean bill of health. It's like finding a plant that's as safe as a pile of socks—no toxicity reports or red flags raised. Not listed as toxic by authoritative sources like the ASPCA or similar health organizations.

Ornamental Bistorts (e.g. Red Bistort – Persicaria amplexicaulis) Ornamental bistorts are commonly planted decorative garden species. They are closely related to Japanese knotweed and are in the same genus as Himalayan knotweed (Persicaria wallichii).

Real beauties of the landscape, Persicaria (Fleeceflowers) are annuals, perennials, or sub-shrubs with showy white, pink, or red flowers in long-lasting spikes throughout the summer. Moisture-loving plants with creeping stems, they include a wide range of varieties with various heights and habits.
