There are many cultivars available of this fast-growing annual. They are best used as bedding, edging, or container plants. Panicles of blue, pink, purple, or white flowerheads arise from oval, downy leaves in midsummer and continue until frost. They have a soft, fuzzy appearance and attract butterflies.

This early, compact bloomer grows to only about 6 or 7 inches tall. With its icy blue-purple flowers, it works well when planted tightly along the foreground of a bed. Its color blends easily with most other hues and textures. -Julia Jones, Designing with annueals, Fine Gardening issue #120

(Bachelor's buttons, Bluebottle, Cornflower)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Bachelor's buttons bear charming and prolific flowers in hues of blue, pink, lavender, white, and maroon. Those with a true blue color are especially welcome in the garden as that color is rare in nature. Each disc-shaped flower is about 1.5 inches across, with ragged petals radiating out from the center.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Unlike most trailing lobelias, this cultivar does not falter in hot temperatures. Techno® Blue is covered in intense, cobalt blue flowers. Its semitrailing, mounding habit is a great addition to containers and hanging baskets.
