Sisyrinchium ‘Iceberg’ / P9

Sisyrinchium ‘Iceberg’ is a delightful variety of Blue-eyed Grass, not actually a grass but a member of the iris family, prized for its elegant white flowers. The ‘Iceberg’ cultivar is known for its purity of color and grass-like foliage, making it a favorite for garden borders, rock gardens, and as a ground cover. The P9 indicates it’s typically sold in a pot size of 9 cm, ideal for gardeners looking to establish or expand their perennial beds or for those interested in container gardening.

Why we like it:

• Pure White Flowers: Offers a crisp, clean look that contrasts beautifully against the green foliage.
• Compact Form: Grows in neat, tidy clumps that are ideal for small spaces or as a border plant.
• Low Maintenance: Requires minimal care once established, making it a great choice for both novice and experienced gardeners.

What to know:

• Soil Requirements: Prefers well-drained soil and is relatively drought-tolerant once established.
• Watering Needs: Water regularly during the first growing season to establish a deep, extensive root system, then reduce frequency.
