The trophy is random and it depends on where the Xenoflowers spawn. To unlock it you have to gather the bonuses from 3 different Xenoflowers. All of them must be active at the same time.
You can opt to increase the duration of a bonus by unlocking the corresponding skills in the abilities menu. Sometimes, Xenoflowers spawn close to each other. Like in this video. When you see three different Xenoflowers move from one to another and activate them to unlock the trophy.
