My wife’s favorite flower is the daffodil. I wanted to buy her some bulbs for Valentine’s Day that she could plant this spring and I wondered if they could be used in magic like other flowers like Lilacs and Roses.
I know they’ve been talked about before in relation to Imbolc and Ostara. I also know this topic would have been great for another challenge. But when I use the earth element (North) in my circle casting and spells, I think of Gaia, Green Witches, trees with deep roots, and the symbolism behind many of the flowers, especially the lotus.
Turns out, daffodils are poisonous to pets. 
Since I love my 3 cats, I don’t believe I will be buying her bulbs this year. 
But I did find some magical uses.
From Learn Religions:
Using Daffodils in Magic
- Put fresh daffodils in a vase in your home to bring about abundance.
- Place daffodils on your altar during workings related to love, especially if it’s a new relationship and you’re still trying to figure out how to navigate the waters.
- Add potted daffodil bulbs, don’t worry if they’re blooming yet, to your altar for spring celebrations, along with other spring flowers such as forsythia, crocus, and snowdrops.
- Wear this flower close to your heart to draw love, but be careful that your love is not one-sided.

Maybe only one or two on my wall altar this spring? 
They would be useful for me and pretty for her - even if not a Valentine’s gift. (By the way, which me luck because I still need to get her something before tomorrow.) We’ll see.
