Planting Annuals Around a Specimen Plant in Containers

Instant colour while your star plant takes centre stage—eventually 

When you plant a striking specimen—like a hardy Hibiscus, small shrub or young perennial—in a container, it can look a little underwhelming at first. These feature plants take time to fill out and shine. But there’s a clever trick to make your container look full and colourful straight away: plant annual bedding around the base. 

This approach gives you the best of both worlds—long-term structure from the specimen, and instant seasonal colour from bedding plants. 

 

🌿 Why Use Bedding Around Specimens? 

  • Fills out the space while the main plant establishes 

  • Adds instant colour and texture 

  • Attracts pollinators 

  • Helps keep soil shaded and moist 

  • Easy to swap out as seasons change 

It’s ideal for newer containers or fresh transplants that haven’t yet made their visual impact. 

What You’ll Need 

  • A large container (at least 40–50cm wide) 

  • Your specimen plant (e.g. Hibiscus, Hydrangea, Dwarf Rose, Agapanthus, etc.) 

  • Good-quality multi-purpose compost with added drainage 

  • Slow-release fertiliser 

  • A mix of bedding plants—such as Lobelia, Petunias, Calibrachoa, Geraniums, or Begonias 

  • Watering can or hose with a rose head 

🌼 Step-by-Step: Planting Annuals Around Your Specimen 

  1. Plant your specimen first 
    Position it slightly off-centre if you like a more natural look, or centrally for a symmetrical design. Make sure the root ball sits at the right depth. 

  1. Add compost and firm in 
    Fill around the roots with compost and firm gently. Leave space at the top for watering. 

  1. Choose complementary bedding 
    Go for compact, sun-loving annuals if your container will be in full sun. For shadier spots, choose Impatiens, Begonias or Lobelia. 

  1. Plant the bedding around the base 
    Use 4–6 bedding plants, depending on the size of the pot. Leave space for airflow and future growth. 

  1. Water in thoroughly 
    Both the specimen and bedding will need a good soak, especially if planting in July or August. 

🌞 Ongoing Care 

  • Water regularly, especially in warm weather. Bedding plants dry out fast in containers. 

  • Deadhead spent flowers to keep blooms coming. 

  • Feed weekly with a liquid fertiliser if you didn’t use slow-release granules. 

  • As your specimen starts to grow and take up more space, remove or replace bedding as needed. 

🧠 Tip: Change with the Seasons 

Come autumn, swap summer bedding for pansies, violas or trailing ivy. In spring, try underplanting with violas or forget-me-nots for a fresh, seasonal update. Your specimen will eventually fill the space—but until then, let the annuals do the heavy lifting for colour and interest.
