Using the tried-and-true “thriller, filler, spiller” method, these arrangements are designed to be showstoppers. Follow these step-by-step instructions to create five unique container gardens that will bring vibrancy and joy to your summer space.

1. Tropical Paradise: A Bold and Lush Statement

Bring the tropics to your backyard with vivid colors and dramatic foliage.

You’ll Need:

  • Thriller: 1 Canna Lily (choose varieties like ‘Tropicanna’ for striped foliage and orange-red blooms)
  • Filler: 2-3 Coleus plants (look for ‘Kong Rose’ or bright lime varieties)
  • Spiller: 2 Sweet Potato Vines (chartreuse ‘Margarita’ and deep purple ‘Blackie’)
  • Container: A tall, wide planter in a neutral or terracotta tone.

How to Assemble:

  1. Start with the canna lily: Place it slightly off-center in the container for a natural, layered look. This plant will add height and drama.
  2. Add the coleus: Surround the base of the canna lily with coleus plants, ensuring their bright leaves are evenly spaced. Their vivid foliage will create a lush, full look.
  3. Finish with sweet potato vine: Tuck the vines around the edges of the container. Allow them to trail over the sides to soften the overall design.
  4. Water thoroughly and place in a sunny spot.

Style Tip: Use pots with earthy textures to enhance the tropical vibe.
