More About Lobelia ‘Magadi™ Compact Blue Bay’

Lobelia ‘Magadi™ Compact Blue Bay’ produces crisp blue flowers with clean white eyes, offering a fresh, classic lobelia look in a tidy, compact plant. The blooms are held densely over the foliage, creating a strong block of color rather than a loose or trailing effect.

This variety was bred specifically for uniformity and control, making it ideal for smaller containers, edging, and mixed plantings where a neat habit is essential.

Why We Like It (Our Trials)

In our trials, ‘Compact Blue Bay’ has performed exceptionally well in spring containers and cool-season plantings. It establishes quickly, flowers heavily, and maintains its compact shape without stretching or thinning.

We especially appreciate its reliability in mixed containers. The clear blue color pairs beautifully with whites, yellows, soft pinks, and silvery foliage, providing contrast without overpowering companion plants.

Lobelia ‘Magadi™ Compact Blue Bay’ vs. Other Lobelia

Compared to trailing lobelias, this selection offers a more controlled, mounding habit, making it better suited for edging and tight container designs.

For gardeners seeking a compact, refined blue lobelia for spring displays, Lobelia ‘Magadi™ Compact Blue Bay’ is an excellent choice.
