Longer stem ROSES tend to have larger heads and a higher petal count. They are better for arrangements or bouquets where you want to use a larger, fuller head. Rose Care Your ROSES will arrive packed in bunches. Trim about 1 off the bottom of the stem and put them in fresh water. Leave the plastic wrap around the roses in place for about 6 hours while the roses re-hydrate. When arranging the roses, trim the stems again and carefully remove any loose or imperfect petals. The outside petals are known as the guard petals and that is exactly what they do, guard the inner petals. As the rose opens, you may need to remove more petals that may have imperfections. Store your roses in a cool place. Remember that the cooler the temperature, the slower the flowers will open and the longer they will last. Do not expose fresh flowers to freezing temperatures. Re-cut the stems and change the water every 2 to 3 days, or as needed.
