Despite having a preference for cool weather, the Icelandic poppy still enjoys lots of light. Before planting, check the average summer temperatures in your area, as these poppies struggle to tolerate temperatures over 25 degrees Celsius. If you’re in cooler northern or coastal regions of the UK, plant the poppy in a sunny spot.
If you live in a warmer region, protect them from unwanted heat by planting in fertile, well-drained soil in a partially shaded position and water regularly until fully established. Once established they will need little attention, making them perfect for low-maintenance gardens and will flower continually May-August.
