A count of 0 for a status means no relationship of that type was found in the studies we reviewed. "No verified relationship" records are explicit findings of no usable evidence for a popular pairing. "Not yet reviewed" means the editorial review has not reached this plant at all, so nothing can be inferred. Check the evidence coverage and last-reviewed date on each card.
119 reviewed records across 63 plants. We synthesize peer-reviewed research, university extension publications and trusted horticulture resources. Each record names its direction, mechanism, context, source, limitations and reviewer.
