Petchoas are a cross between petunias and calibrachoas with large vibrant flowers in full sun to part sun. They quickly reach 10-14" tall x 12-18" wide in borders, mass-plantings, containers. They attract butterflies and hummingbirds.
If they start to slow down their blooming, or look a little bit ragged, you can shear them back to about 8 inches tall. They wil bounce back into full bloom in about 10 days!
