Plant this If you’re looking to delight bees, Mexican giant hyssop (Agastache mexicana) is a sound choice for sunny, well-drained borders and containers. It makes a tasty tea and the flowers last into autumn. ‘Blackadder’ has steel blue flowers, or there’s deep pink ‘Red Fortune’.

Cut this Once euphorbias’ show of lime-green flowers is over, remove the flowered stems right back to the base: this will allow room for new stems to develop, that provide next year’s blooms. Wear gloves and long sleeves as euphorbias produce a toxic milky sap that when cut, will burn skin.
