Midnight Blue Lobelia (Lobelia erinus ‘Midnight Blue’)

Midnight Blue Lobelia (Lobelia erinus ‘Midnight Blue’) is a beautiful flowering annual prized for its abundance of rich deep blue blooms and elegant trailing habit. This compact variety creates a stunning display of intense blue flowers that blanket the plant from late spring through fall, making it a favourite for hanging baskets, containers, window boxes, and garden borders.

The small yet abundant flowers create a waterfall of colour that contrasts beautifully against bright green foliage. The rich blue blooms bring cool tones to mixed plantings and pair exceptionally well with white, pink, yellow, purple, and silver companion plants. Their long flowering season provides continuous colour while attracting bees and other beneficial pollinators to the garden.

Midnight Blue develops a dense, mounding to gently trailing habit that softens container edges and fills garden spaces with colour. Its compact growth makes it an excellent choice for smaller gardens and decorative planters where season-long performance is desired. The vibrant blue flowers provide a refreshing accent during the warm summer months.

In Alberta, Midnight Blue Lobelia performs best during the cooler temperatures of spring and early summer, often continuing to flower well into fall with proper care and consistent moisture.
