Roses are probably the most popular flower in history. Evidence suggest that roses have been used by mankind for thousands of years, as quite apart from its intrinsic beauty, it was valued for its fruits for a source of vitamin C as well as for its restorative powers, also for its beautiful wood and as a highly valuable ingredient in essential oils and perfumes. Roses should be hydrated with the cardboard sleeves on. This will ensure that the stems draw water and hydrate in a fully erect position. After 24 hours the rigid cardboard sleeve should be removed, or at least loosened as it will restrict proper hydration of the blooms. Roses greatly benefit from cutting underwater, and while this is an extra step, if I had to pick one flower to perform this process on it must be roses.
