Answer 1

Roses

Crown gall (caused by Agrobacterium tumefaciens) is commonly seen on roses and many other broadleaf (dicot) plants, producing tumor-like galls at the crown, roots or stems. It’s uncommon on grasses (like Bermuda grass) and on most conifers (e.g., pines, oaks are less typically affected).
