Colorful Combinations

Little trumpets of color, calibrachoa flowers play their fanfare day in and day out. With new developments in breeding, calibrachoa flowers now come in a rainbow of options, including yellow stars, speckled colors, veined and segmented petals, and sometimes combinations of all of the above. Plant calibrachoa in a sunny window box for extra curb appeal.

Much of the work that's gone into calibrachoa breeding has been to make these plants day-neutral. This means that they bloom all season, no matter how long or short the days are.

Calibrachoa Care Must-Knows

A fairly low-growing plant, calibrachoa doesn't typically get much taller than 4 inches. Its spread is what draws attention: Some plants can extend over 2 feet of ground in no time. If you're looking to quickly fill a container or hanging basket, this plant is up to the task! Calibrachoa also does well when mixed with other plants or tucked into the front of a border, where it can spill out onto sidewalks or patios.

One thing to note about calibrachoa: Since it's such a fast grower, the plant requires a decent amount of food and will let you know if it needs to eat. Sensitive to low amounts of nitrogen, calibrachoa turns yellow when it needs to be fed. So if your plants look a little golden, it's time to give them a nice dose of fertilizer.

Calibrachoa also does a pretty good job of "burying their dead"; meaning they grow so fast, they quickly cover over any old blossoms. This is a plus for low-maintenance gardeners, as there's no need to manually remove dead growth.

New Innovations

Recently, there's been some interesting work being done with calibrachoa plants. An example is the creation of the "petchoa": a cross between a petunia, a close relative, and the calibrachoa. This new hybrid looks a lot like you might expect, considering its parents: A giant, flowering plant with a mounded habit. The best of both worlds.

Calibrachoa Companion Plants

David Speer

Angelonia

Angelonia is also called summer snapdragon, and once you get a good look at it, you'll know why. It has salvia-like flower spires that reach 1-2 feet tall studded with fascinating snapdragon-like flowers with beautiful colorations in purple, white, or pink. It's the perfect plant for adding bright color to hot, sunny spaces. This tough plant blooms all summer long with spikes of blooms. While all varieties are beautiful, the sweetly scented selections offer an added bonus. While most gardeners treat angelonia as an annual, it is a tough perennial in Zones 9-10. Or, if you have a bright, sunny spot indoors, you can keep it flowering all winter.

Coralbells

Exciting new selections with incredible foliage patterns have put coralbells on the map. Previously enjoyed mainly for their spires of dainty reddish flowers, coralbells are now grown as much for the unusual mottling and veining of different-color leaves. The low clumps of long-stemmed evergreen or semi-evergreen lobed foliage make coralbells fine groundcover plants. They enjoy humus-rich, moisture-retaining soil. Beware of heaving in areas with very cold winters.

Cynthia Haynes

Loosestrife

These vigorous growers are beautiful additions to the garden. They vary from tall, stately plants suitable for borders to others that can be planted as creeping groundcovers. Flowers, too, vary from tight spikes of 1/2-inch to 1-inch cups carried alone or in whorls. Humus-rich, moisture-retentive soil is recommended; some varieties enjoy wet soil and ample water. Several sorts may become invasive and need to be corralled. Note: These are not the invasive purple loosestrife, which has been banned in many parts of the United States.
