This is a subtle Textual Inversion Style Embedding trained on colorful wildflowers. You can get amazing bright flowers and nature-greens in your images by calling Style-Petal in the positive prompt, and if you want to temper the effect, also call Style-Petal-neg in the negative prompt.

If you'd like the effect to come through stronger (some models need it), try bumping up the emphasis on Style-Petal - see the images below.
