A month ago I put a pair of Hosta leaves that were just beginnng to yellow at the edges in my favorite vase. I added a pair of tall reeds from the bog garden and a stalk of white Hosta flowers, aka August lilies. When the flowers faded, I replaced them with a Peony seedpod.
Over the last few weeks as the water in the pot has evaporated, the leaves have continue to yellow and curl up while the seed pod has popped open. I love watching plants transform themselves from one growth stage to another, and there's no better place to watch this happen than in a vase in the house.
