Eschscholzia californica 'Ivory Castle'
Elegant ivory-white California poppy with drought-tolerant summer flowers

Eschscholzia californica 'Ivory Castle' is an elegant California poppy producing delicate creamy-white flowers with soft yellow centres above finely divided blue-green foliage. This refined colour form offers a softer alternative to the traditional orange California poppy, creating a light and natural appearance in summer planting schemes.

Easy to grow and highly drought tolerant once established, 'Ivory Castle' thrives in sunny, well-drained locations and performs particularly well in borders, gravel gardens, rockeries and wildflower-style planting. The plants flower freely throughout the warmer months and can self-seed naturally where conditions are suitable.

Expert Growing Tips

● Direct sow where plants are to flower, as California poppies develop a long taproot that dislikes root disturbance.

● Avoid rich soils and excessive feeding, as poorer soils encourage more flowers and a stronger natural habit.

● Autumn sowing can produce earlier flowering plants the following year in suitable UK gardens.

● Allow some seed capsules to mature if you want plants to self-seed naturally around the garden.

● Plant in the sunniest, driest position available for the best flowering display and strongest growth.
