'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.

  • Garden care:
    Grow plants in well-drained soil where they require ample sunlight for their blossoms to unfurl. They can also be cultivated as pot plants that are tolerant to drought conditions. They are particularly suitable for areas that are exposed or situated along the coast. It is advisable to prune them back once they have finished flowering.

  • Sowing instructions:
    Sow seeds outdoors where they are to flower, covering the seed to a depth of 3mm (1/8in). When large enough to handle thin out the seedlings to 30cm (12in) apart. Sowing can be done from March to May, or for an early flowering crop the following year, August to October.

  • Sow: March to May (or August to October for a display the following year)
