Funnel-shaped flowers differ from flowers with a similar form such as campanulate flowers that have a bell shape, tubular flowers that are longer than they are wide, and bilabiate flowers that have two long, joined petals and three short, joined petals. Plants with funnel-shaped flowers are sometimes called trumpet-shaped flowers. Many plants produce funnel-shaped flowers.
Morning glories are a family of vines that may be considered a flower or a weed. The vines have a counter-clockwise growing habit that wind around supports such as wooden trellises or wire fences. Morning glory flowers may also be known as trumpet-shaped because the flower has one petal that is shaped like a musical instrument. In weed form, morning glories may be known as field bindweed.
Petunias are an easy-to-grow annual that prefers full sun. The flowers have a spreading habit that makes them a good choice for ground cover. Petunias are difficult to start from seed, due to the small size of the seed. Instead, many gardeners prefer to purchase plants from garden centres and transplant them into the soil of their gardens.
