Sea Holly 'Big Blue'

This plant requires full sun, which means at least six to eight hours of direct sunlight daily. Planting it in a shaded area will likely result in weak stems and poor flower production.

Yes, once established, its deep taproot allows it to handle dry conditions well. However, you should provide regular water during its first growing season to help that root system develop properly.

Absolutely. It is an excellent cut flower that holds its structure and color well in bouquets. You can also leave the flower heads on the plant to dry naturally for winter interest in the garden.

Sea Holly is generally considered deer resistant due to its prickly texture and tough foliage. While no plant is entirely deer-proof, it is a reliable choice for gardens where browsing animals are a concern.

The most important requirement is excellent drainage. If you have heavy clay soil, amend it with organic matter or grit to ensure the roots do not sit in water, which can lead to rot.

Since 'Big Blue' reaches a mature width of about 2.5 feet, you should space them at least 24 to 30 inches apart. This ensures good air circulation, which helps keep the plant healthy.
