There are hundreds of bell-shaped flowers to choose from. I’ve explored 19 that appeal to me and one that I would not recommend, even to an enemy – the morning glory is highly invasive and should be avoided.

Tubular or bell-shaped flowers are most appealing for their inclination to attract hummingbirds (and other pollinators). Bell-shaped flowers are not family-specific, i.e., they are not primary category identifiers. The inflorescence type is generally raceme.

Let’s explore my selection of 20 bell-shaped flowers. They’re alphabetically listed:

1. American Bellflower (Campanula americana)

Eastern North America’s damp open forests, meadows, streambanks, and ditches are home to the annual or biannual American Bellflower. Numerous kinds of bees, wasps, butterflies, and hummingbirds will visit and look for nectar and pollen, making it a pollinator magnet.
