Calibrachoa pours out tiny trumpet flowers all season long, densely mounding to fill gaps in beds and spill generously over pot edges. Each plant cranks out hundreds of blooms in shades that range wide—pick your color or mix several for impact.

Sun-lover that needs regular water but rewards you with nonstop color from late spring through heat. Space them 12 inches apart in the ground, or pack three to four in a hanging basket for that full, flowing effect by mid-season.
