Bright yellow blooms compliment all other colors and the constant blooms smother the plant. Among the easiest plants to grow, Million Bells are hugely popular, just ask any hummingbird. Their profuse, self-cleaning flowers arrive in spring and keep going until fall. Excellent for hanging baskets, mixed pots, and flower beds.
Provide plenty of sun and good garden soil. Fertilize with a slow release granular bloom booster such as Osmocote or Miracle Gro.
