Is the Dipladenia a perennial?

Question

How much sun does the Dipladenia need? Can I plant them in flower beds? Or do they do better in pots?

Answer 1

Dipladenia is perennial, rated for USDA plant hardiness zones 9-11. Dipladenia prefer bright but indirect sun. Given that your planting zone is 6a you will probably want to pursue dipladenia as a potted plant. You can situate your potted plant outdoors until temperatures dip below 60 degrees.
