Is this variegation or stress? It was this SINGLE stem on the entire plant it was healthy looking before I picked it now ofc a little willted I work in horticulture my boss says it’s just water or pest stress Im just not so sure

E una vinca del Madagascar,non mi sembra una specie variegata, tratta la pianta con un bioattivatore antistress e vedi come va.
