How to Choose and Grow Summer Flowering Bulbs

Choosing summer bulbs is really about knowing where you want to plant them and what sort of result you’re hoping for once summer arrives.

  • For pots and patios, compact bulbs like begonias, freesia, and calla lilies tend to stay tidy and are easy to look after
  • For borders, taller plants such as gladiolus, lilies, and liatris mix well with perennials and help fill space
  • For longer flowering, dahlias and mixed summer bulb collections usually keep going for weeks
  • For scent, lilies and freesia add fragrance without being too strong

Plant summer bulbs in free draining soil once frost is no longer a concern, water them after planting, and keep the soil slightly moist as shoots appear.
