Colibri Plum, also known as Million Bells or Trailing Petunia, is a flowering plant native to South America. Perennial in zone 10-11, Calibrachoa is typically grown as an annual that's particularly well-suited to hanging baskets and containers. Danziger developed the Colibri series for its tidy controlled habit and early blooming under ten-hour days. This cultivar has a compact mounded habit of 10-12" tall and wide with prolific trumpet-shaped purple flowers with yellow centers from spring through late fall. Bring whimsical color to a front porch or patio with Colibri in hanging baskets, mixed containers, or window boxes.

General Growing Tips For Your Rooted Cutting Liner
For best results with Colibri Plum, plant one rooted plug per 4-inch container or three per 10-inch basket. Use a well-drained soil with a pH of 5.6-6.0, EC of 1.0-1.2, light feed (100-150 ppm N), and temperatures of 65-68 daytime and 52-62 nighttime. The Colibri series will bloom under 10-hour days. You may see aphids and thrips, and this plant can be prone to botrytis and root rot. Pinch once if desired and apply a paclobutrazol drench when the plant is about 85% of its final size. Apply a fungicide at transplant.
Flowering
Purple flowers with white centers bloom from spring through late fall.
Pinching
Pinch once if desired.
Spacing
Space containers for adequate airflow and sunlight penetration around the base of each plant.
Height Control
Apply a drench of paclobutrazol at 1-2 ppm when the plant is about 2/3 its final size.
Pests
You may see aphids and thrips.
Disease
This plant can be prone to botrytis and root rot when the days are short or in wet, humid conditions. Calibrachoa needs adequate moisture to grow, but keep it on the dry side in the greenhouse to avoid root rot. Water at the base of each plant in the morning and again in the afternoon if needed. Do not water at night. Provide good airflow in your greenhouse and allow sunlight to penetrate to the soil level of each plant by giving enough space between containers. We recommend using horizontal airflow fans.
Planting Colibri Plum Liners
We recommend planting one rooted liner per 4-inch container or three per 10-inch basket. Use a well-drained soil and completely bury the ellepot centered or evenly spaced in the container.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
