'Ivory Castle' is a bushy annual with finely divided, feathery, blue-green foliage and single, creamy-white flowers in summer. Hardy throughout the UK, this California poppy has a remarkable ability to thrive in poor and dry soils and coastal locations, making it an effortless addition to your borders, rockeries, and alpine troughs.
How to care for Eschscholzia californica Ivory Castle:
Choose a site in full sun with well-drained soil; they thrive in poor, sandy ground and don’t need enriched compost or ground. Water sparingly once established, as they are drought-tolerant and dislike waterlogged soil. Deadhead regularly to prolong flowering. Little to no feeding is required, as too much fertiliser encourages leaves rather than flowers.
Sowing instructions:
Prepare the bed well and sow Californian poppy seeds shallowly into drills from from March to May where they are to flower. When large enough to handle thin out the seedlings to 10-15cm (6in) apart, taking care not to damage the tap roots of the retained seedlings. Water when necessary, but avoid excessively wet conditions. Seeds sown in late summer and early autumn will flower earlier than those sown in spring.
