Everlasting may be an exaggeration, but these blooms will last through a couple winters.
These are dried hydrangeas.
Do you know what's an amazing thing about hydrangea blooms? When you cut them to bring indoors for a vase, you don't have to do much of anything to produce lovely dried blooms.
You simply fill a vase with water, trim the stems of your blooms, remove excess foliage, place the stems in water, and allow them to dry, as the water evaporates.
I've done this the past couple of summers. It always amazes me, because so many other flowers don't look so great after a few weeks in a vase of water. But hydrangeas do dry so nicely, and so easily. They fade some, as they dry, and then a bit more after drying.
I think they're beautiful. Delicate, china blue petals. A remembrance of summer, when the winter light is dim and icy.
