Radiation, also known as Red Sage and Lantana Camara, is a tender perennial native to Central and South America. This variety offers an upright, bushy habit of 4-6' tall and wide, with orange-red and yellow flower clusters blooming from spring through summer in cool-weather areas and nearly year-round in zone 9-11. This plant is evergreen and root hardy in warm climates and grows well as an annual in cold regions. Vibrant flowers attract butterflies and hummingbirds to sunny landscape borders, flourishing in full sun with minimal water. This large Lantana is well-suited to use as a low hedge or shrub, bringing a heat-tolerant show of color to the garden.
Radiation Selling Tips
Sell Radiation to customers looking for a vibrant flower for use as a shrub, hedge, or landscape border. Customers, butterflies, and hummingbirds love Lantana's vibrant colors and long bloom season. This plant offers a mounding habit with elegant flower clusters that flourish in full sun with minimal water or care. Create a charming landscape rife with texture and color by growing Lantana alongside Angelonia, Pentas, and Salvia.

General Growing Tips For Your Rooted Cutting Liner
For best results with Radiation, plant one rooted plug per 4- or 6-inch container. Use a well-drained soil with a pH of 5.8-6.2, EC of 1.0-1.2, temperatures of 73-75 daytime and 65-68 nighttime, and light feed (100-150 ppm N). Pinch once at transplant and use paclobutrazol to control growth if needed. Watch for thrips, aphids, whiteflies, leafminers, botrytis, and root rot.
Flowering
Orange-red and yellow flower clusters bloom from spring through summer, or nearly year-round in in warm climates.
Pinching
Pinch once at transplant.
Spacing
Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant.
Height Control
Control growth with a paclobutrazol drench at 1-2 ppm if needed.
Pests
You may see aphids, whiteflies, thrips, and leafminers.
Disease
This plant isn't prone to disease but botrytis and root rot can develop in cool, wet, humid weather or overly wet conditions. Take preventative measures in your greenhouse and use a fungicide drench at transplant if desired.
1. Water at the base of each plant in the morning, allowing the soil to dry out between waterings.
2. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans.
3. Space containers so each plant has airflow and sunlight penetration to the soil level.
Planting Radiation Liners
We recommend planting one rooted liner per 4- or 6-inch container. Use a well-drained soil and completely bury the ellepot in the center of 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.
