This also helps preserve the fresh lily fragrance of your arrangement. Adding commercial flower food can help prolong the life of cut lilies. However, lilies require only about half the dosage recommended for other flowers. Flower Arrangements A classic tenet of flower arranging holds that young buds and tender pointed leaves be placed at the top of an arrangement and that larger, more dominant flowers be placed at the bottom. Lilies flower this way naturally.
Lilies are strong enough to carry an arrangement all by themselves.
However they also mix well with other flowers. Even one lily stem can dress up an arrangement of more modest flowers. Lilies should be placed centrally in an arrangement, preferably in the lower two-thirds. Lilies are large, fairly heavy flowers that require suitably large containers. In summer, lilies are abundant both in the garden and at florists' shops.
