Calibrachoa flowers come in a rainbow of colors, including yellow stars, speckled colors, veined and segmented petals, and sometimes combinations of all of the above. Their fanfare-like trumpeting is often the first thing you'll notice about these blooms when they emerge from the ground - it's no wonder they've been given the nickname "the chirping flower!" Flowers may be solitary or in groups, and vary in size from large enough to fit in your hand to smaller flowers that sit atop short stems.
