Reddit mentions of Folklore and Symbolism of Flowers, Plants and Trees (Dover Pictorial Archive)

Seconding u/theUnmutual6's recommendations, in addition to u/BlueSmoke95's suggestion to check out Ann Moura's work. I would like to recommend Ellen Dugan's Natural Witchery and her related domestic witchery books. Ellen is a certified Master Gardener and incorporates plants into much of her work.

Some of my favorite plant books!

Plant Science:

• Plant Physiology and Development (you can get away with the previous edition of this one!)
  
  
• Botany for Gardeners
  
  
• Essential Plant Pathology (do NOT get the first edition - the second edition is superior in almost every single way)
  
  
• American Horticultural Society Plant Propagation: The Fully Illustrated Plant-by-Plant Manual of Practical Techniques
  
  
  Foraging & Field Guides:
  
  
• A Field Guide to Edible Wild Plants: Eastern and central North America
  
  
• Edible Wild Plants: Wild Foods From Dirt To Plate
  
  
• The Forager's Harvest: A Guide to Identifying, Harvesting, and Preparing Edible Wild Plants
  
  Herbalism:
  
  
• Rosemary Gladstar's Medicinal Herbs: A Beginner's Guide: 33 Healing Herbs to Know, Grow, and Use (this is the first one I would recommend to novices)
  
  
• The Herbal Apothecary: 100 Medicinal Herbs and How to Use Them
  
  
• The Herbal Medicine Maker's Manual
  
  
• 300 Herbs: A Materia Medica
  
  
• Culpeper's Complete Herbal
  
  Ethnobotany:
  
  
• A Modern Herbal Vol I and Vol II (these could belong in the above section or here - I love love love these books. I think they are a must for any hedge witch or green witch!!)
  
  
• Folklore and Symbolism of Flowers, Plants and Trees
  
  
• Whispers from the Woods: The Lore & Magic of Trees
  
  
• Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge and the Teachings of Plants
  
  I also encourage y'all to look into fungi as well. I work with both plants and fungi and I think they bring a fascinating and fulfilling aspect to my work. Plus, hunting for mushrooms is super fun! I can recommend field guide books for folks who are interested, they just tend to be very region-specific so I'm not going to list all of them here.
  
  For general fungus reading I recommend the following:
  
  
• Magical Mushrooms, Mischievous Molds
  
  
• The Fifth Kingdom
  
  
• Mycelium Running
  
  
• Radical Mycology: A Treatise on Seeing & Working with Fungi
  
  
• Mushrooms Demystified
