Though moonflowers can't speak in the conventional sense, they communicate telepathically with other moonflowers. Explorers who encounter a single moonflower can thus be assured that any other moonflowers in the vicinity will be prepared for them. Those who manage to intercept a moonflower's telepathic communications are assaulted by visions of dreadful, primeval jungles ruled over by titanic plant life. Whether this is some vision of the past or a dream of the future shared by all moonflowers is unknown.
