The Blue Petunia is a spreading annual with deep blue-purple blooms. Their bright flowers attract butterflies and hummingbirds along with other pollinators. Plant your Blue Petunia en masse or in a mixed flower bed for an incredibly colorful spring garden.

In full sun and well-draining soil, these plants are extremely easy to grow; at the end of the season, your Petunia plants can grow up to 1 foot tall but spread 3 feet wide. While we treat Blue Petunias as annuals, they are hardy in zone 11 and can be kept outside all year as a perennial.
