Freeze them in ice cubes. Pluck flower heads and place them in an ice cube tray. Fill the tray with water and freeze for some “summer energy” during the darker, colder winter rituals or to use when the flowers aren’t in season.
Leave a bouquet of wildflowers at the crossroads as an offering to the goddess Hecate when you are facing a difficult decision or major life change.
Make flower crowns for summer rituals. Weaving flower crowns from local wildflowers you gathered by hand the morning of the event lends power and meaning to any ritual. And you can make them any time of year. I posted instructions for a winter version here, but the same basic technique applies.
Make a blessing jar. Get a vase or mason jar, place some meaningful gemstones in the bottom, fill with water and create wildflower arrangement that includes herbs & flowers chosen for their intent. Place it near a window to bless your home, or give it away to a friend.
Plant them in your garden. While many wildflowers tend to be invasive in the regions where they grow, that also makes them almost impossible to kill if your thumb isn’t so green. Many produce seeds that can be gathered, but some you can just pull up by the root and transplant to a pot.
Add them to cupcakes for the Cakes & Ale portion of a ritual. Hopefully, it goes without saying that you need to check to make sure the flowers are actually edible, and especially to make sure they aren’t poisonous. Lots options exist within those boundaries. For inspiration, check out this example of fairy cakes made with candied violets.
Press them in your Book of Shadows. If you have a specific spell that requires a flower which grows seasonally in your area, gather a few during the growing season and press them into the pages where you wrote the spell. That way, when you go to cast, your key ingredient remains conveniently nestled in the pages with it.
Mark the circle. Go on a nature walk before your ritual and gather enough flowers to ring your casting circle. This makes an especially lovely bonding experience for coven rituals.
Create seasonal smudge wands. Nothing adds a delicate touch to the ritual like fresh, local foliage. If you know your local flowers and their associations, making smudge wands puts put that knowledge to use in visually pleasing way. And if you don’t know your alchemic way around queen anne’s lace or black-eyed susans, you can always I’ll be happy to make one for you .
Roll them into candles. Gently heat a pillar candle in the oven until it’s just beginning to melt on the outside, then roll it on dried flowers. Looks gorgeous on the altar.
Make salves and tonics to treat mild ailments. If you’re well-versed in the medicinal or magical properties of your local herbs, take this time in the season to make a store of home remedies for cold & flu season.
