  • Fast establishment

  • Usually replanted each year

Perennial Flowers

Perennial flowers return year after year in suitable climates, providing long-term colour and structure.

  • Long-lived plants
  • Lower maintenance once established
  • Excellent for permanent gardens
  • Many attract pollinators

Many Australian gardeners combine annuals and perennials to achieve instant colour while establishing long-term flowering displays.

Growing Flower Seeds Successfully

  1. Choose the correct planting season. Sowing times vary between flower species and Australia’s climate zones.
  2. Prepare well-drained soil. Most flowering plants establish best in loose, fertile soil with good drainage.
  3. Sow at the recommended depth. Small flower seeds generally require only light covering.
  4. Maintain consistent moisture. Keep the seedbed moist until seedlings are well established.
  5. Provide adequate sunlight. Most flowering plants perform best in full sun, although some tolerate partial shade.
  6. Thin seedlings if required. Proper spacing improves airflow and flower production.
  7. Remove spent flowers. Deadheading many annuals encourages continued flowering throughout the season.

Growing conditions vary across Australia. Always refer to the individual product page for sowing depth, spacing, planting season and climate recommendations.
