Cut amaryllises, lupines, and delphiniums at a angle. Hollow stems need to stay full of water. After pouring water into the stem, cover the bottom of the stem with your finger while putting the flower in the vase, so the water stays in the stem.
Cinnamon, a mild fungicide, protects against fungi that causes rotting before rooting. Gently press cut stems into ground cinnamon; moisture from stem will pick up proper amount. Plant cutting in sterile potting mix.
