How to Quickly Add Colour to a Garden That Feels Flat

If your garden is looking a bit flat coming into late spring and early summer, you can lift it fast. This is the best time of year to add plants that are already flowering and will keep performing through the hotter months. The goal is simple: choose varieties that give instant impact, settle quickly, and continue to flower or hold strong colour through summer.

Below are easy, reliable options that deliver quick colour using Proven Winners favourites, plus dianthus which always gives fast return.

What You Can Do Right Now

• Fill gaps with plants already in flower.
• Use compact varieties for edging and quick definition.
• Drop trailing and mounding plants into containers for immediate impact.
• Add foliage colour to strengthen the base of tired beds.

Fast-Impact Plants to Use

1. Calibrachoa Superbells

Perfect when you need colour straight away. They flower heavily now and keep going through summer. Ideal for sunny pots, baskets, and edging. Heat tolerant and low care.

2. Petunia Supertunia Vista

One of the quickest ways to add bold, high-volume colour. These mound and trail fast, filling spaces in beds and containers. Flowers from now through autumn with minimal work.

3. Dianthus

A classic for quick colour. Already flowering in late spring with rich pinks, reds, and whites. Compact, tidy, and great for borders or pathways. Returns each year and keeps shape well in summer heat.

4. Fuchsia Shadow Dancer

Great for shaded or sheltered spots that look dull. Already flowering, easy to care for, and ideal for baskets or underplanting.

5. Leucanthemum Whoops A Daisy

White daisies give an immediate lift. Forms a neat mound and flowers early to mid-summer. Good for brightening tired beds and mixing with stronger colours.

6. Heuchera and Heucherella

Foliage plants that give instant colour even before flowers. Varieties like Black Pearl, Wild Rose, and Catching Fire add depth through purple, lime, silver, and near-black tones. Hold colour year-round and support brighter flowering plants.

Quick Planting Tips

• Pick sunny positions for the highest colour output.
• Water deeply for the first week to help plants settle.
• Feed lightly every two to three weeks.
• Trim spent flowers to encourage fresh growth.

Bring Colour Back Fast

Late spring and early summer are perfect for refreshing a garden that’s lacking colour. Mixing Proven Winners varieties with classics like dianthus lets you add instant impact that lasts all season.
