What Is Calibrachoa?
Also known as Mini Petunia or Million Bells
If you’ve ever walked past a planter overflowing with a rainbow of tiny trumpet-shaped blooms, chances are, you’ve met Calibrachoa. Affectionately known as Million Bells, this resilient, trailing plant brings burst-after-burst of color from spring until the first frost—without asking much in return.
Though they resemble petunias, these small wonders are a genus of their own—compact, hardworking, and heartwarming.
Why Gardeners Are Falling in Love with Million Bells

- Comes in vibrant colors like coral, lemon, lavender, and deep velvet purple

How to Grow Calibrachoa – A Beginner’s Guide
USDA Zones: 9–11 (Grown as an annual in cooler regions)
1. Choose the Right Location
Million Bells love the sun. Give them 6+ hours of direct sunlight daily. In hot climates, some afternoon shade helps prolong flowering.
2. Use Light, Well-Draining Soil
Avoid heavy or clay-rich mixes. Use a peat-free potting soil with perlite or coco coir to promote air circulation and water flow.
3. Water Mindfully
Water thoroughly when the top inch feels dry—but don’t let them sit in water. Overwatering can lead to root rot.
4. Feed for More Blooms
A liquid fertilizer every 10–14 days keeps the bloom cycle going strong. Look for a balanced NPK like 10-10-10 or one slightly higher in phosphorus.
5. No Deadheading Required
One of the best things? Calibrachoa cleans itself. Spent blooms fall away naturally, so your plant stays tidy with no extra effort.

How to Propagate Calibrachoa at Home
Calibrachoa can be propagated by softwood cuttings in late spring:
