I spent a lot of time in my backyard as a kid braiding and (attempting) to weave pine needles. Our big old American lawn had tons of clover that I would try to weave into a chain or a crown for my breye horses or for myself. I still have not successfully created a crown of flowers and at this point in my life I’m pretty sure I would just use florist wire.
This is a sweet little diagram of how to make a daisy crown. Erigeron karvinskianus would be a great plant to make one with!
