Day 1: One teaspoon of sugar is added to the water.
Day 4: Except for one limp stem, things look pretty good. One more packet of sugar gets poured into the water.
Day 7: The flowers have burst open, and the petals are beginning to curl. (See photo, left.)
The verdict: Uneven blooming and splayed stems, but the flowers are mostly intact.
