Polina Washington - Botanical Garden Presets Pack
You also get detailed instructions for working with presets and settings.
Presets can be used for both Lightroom Desktop and Lightroom Mobile.
Each preset was created from scratch after one of my shootings. This is what I use now myself, making some micro corrections and not spending a lot of time processing photos.
Please note: any preset needs to be adjusted to the frame (make it lighter, darker, etc.).
