Seasonal Interest and Garden Design

Annual plants are often chosen when parts of the garden start to feel bare, especially between larger planting schemes.

  • Spring usually brings primroses, violas, and early hardy annuals back into beds and containers
  • Summer planting tends to lean toward petunia, lobelia, begonia, and marigold for steady colour
  • Some annual bedding plants keep flowering later than expected, even as the season shifts
  • Biennial plants suit gardeners who prefer planting one year and seeing flowers the next

How to Choose and Grow Annual & Biennial Plants

Most people choose annual and biennial plants based on timing, space, and how quickly they want results.

  • Hardy annuals are often planted first when the weather is still unsettled
  • Half-hardy annuals usually wait until frost feels unlikely
  • Annual plants cope best where the soil does not stay wet for long
  • Bedding plants fill out quickly once space allows
  • Hanging baskets tend to work better with trailing plants like lobelia or petunia

Keeping plants watered during dry spells and removing faded flowers helps keep displays looking fresh.

Frequently Asked Questions

Annual plants flower, set seed, and die within one growing season, so they usually need replacing. Many gardeners enjoy changing annual plantings each year for fresh colour combinations. Some annuals self seed and return naturally.
Yes, many biennial plants can be sown in late summer, including August. This allows them to establish roots before winter and flower the following year. Water well and protect young plants during very cold weather.
Annual plants grow, flower, and die in one season, while biennial plants grow foliage in their first year and flower in the second. Both are popular for bedding displays and seasonal garden colour.
Annual plants are well suited to containers and baskets due to their fast growth. Trailing types such as lobelia and petunia are especially popular for this use.
Half-hardy annuals are best planted once frost risk has passed. That's usually in late spring. When the conditions are warm, it helps them grow more quickly.
