You can put flowers in just about anything. An antique watering can, a tin can, a plastic mug or glass, the possibilities are endless. Some containers work better with water and the flower stems cut to a suitable length.
Shallow containers work better with floating flower heads, such as a shallow bowl or votive cup.
Baskets, ceramic, or clay pots work better when lined with a plastic container, as do oversized or extra-large containers. (Feed can be placed inside the larger container to reduce the size and weight to fill the entire container.
