Q.How Shall I Handle Snow-on-the-Mountain To Use It In Cut Flower Bouquets?
What is the optimum stage for cutting? How long will it hold?

There are a couple of plants that people refer to as snow-on-the-mountain so I'm not sure which one you have. With either of them, cut them early in the morning while the dew is still on. Cut them before they reach their prime. Also, in the bouquets, change the water at least every other day. Bacteria builds up in the water and that is what hastens their death. And be sure none of the foliage is below the water line. You can strip off the leaves on the lower stems.
I think either one will last a week in a vase.
