Discover the best summer flowers, what they mean and how to care for them with this bumper guide.

Caring for a summer bouquet

Before we plunge into the best summer flowers, first a quick lesson on taking care of them. These top tips apply not just to these lovely summer blooms, but most cut flowers – so be sure to remember them!

  • Trim the stems 2-3cm before you put them in the vase, cutting at an angle, this helps the stem take up water. If possible use a clean sharp knife or secateurs (not scissors, these can crush rather than cut the stem).
  • Fill the vase with plenty of clean water.
  • Change the water every few days to help your blooms last longer.
  • They might be summer flowers but they won’t thank you for direct sun. Keep your bunch away from windowsills and conservatories.

Styling summer flowers
