Hey there, fellow garden enthusiasts! I’ve been experimenting with flower boxes for years, and I’m super excited to share my favorite perennial plants that’ll make your containers pop with color and life. Whether you’re working with a tiny balcony or just want to jazz up your windowsills, I’ve got you covered!

Why Choose Perennials for Your Flower Boxes?

Before we dive in let me tell you why perennials are totally worth it

  • They come back year after year (hello, money savings!)
  • Less maintenance than annuals
  • Create stunning displays with different bloom times
  • Perfect for both newbies and experienced gardeners

Best Perennials for Flower Boxes

1. Coral Bells (Heuchera)

These babies are my absolute favorites! They’re perfect for containers because:

  • Height: 8-18 inches
  • Width: 12-24 inches
  • Colors: Orange, pink, coral, red, white
  • Zones: 4-8
  • Light needs: Full sun to partial shade

Pro tip Try the ‘Electric Plum’ variety for some seriously gorgeous purple foliage!

Talk about easy-peasy! These beauties are super low-maintenance:

  • Height: 24 inches
  • Colors: Lilac, blue, white
  • Zones: 3-7
  • Perfect for cooler temps
  • Blooms in June and July

3. Dianthus

Y’all these are like the little workhorses of the flower box world

Container Growing Tips

Listen up! Here’s what I’ve learned the hard way:

  1. Drainage is Everything
  • Make sure your containers have good drainage holes

  • Add a layer of gravel at the bottom
  1. Size Matters
