Answer: Phormium (New Zealand Flax) grows in my Seattle garden, so it should grow well for you - in a place protected from icy winter winds. The biggest problem for these plants is soggy soil. Provide a garden bed that drains extremely well (I planted mine in a raised planter) and the roots should survive even the wettest weather. A southern exposure will be perfect for this plant. If icy winds threaten, you can put up a temporary screen to protect the foliage. Once your plant is firmly established, the roots will replace the foliage if it's lost to and exceptionally cold winter weather pattern. Best wishes with your new plant!
