Funeral flower arrangements placed on the altar at the service typically include large blooms that can be admired from a distance. A smaller funeral bouquet is typically placed next to the guest book. Many altars in churches and funeral homes have low light so selecting a bright or white flower arrangement, such as one that contains a lily flower or white rose, is advised. Remember that tall, bright bouquets with large blooms are best on the altar, so that the congregation can easily see them.
