Nursery contributed plant descriptions

Phormium have cornered the market on structure and drama which is likely why they’re so popular. 'Yellow Wave' is a bright and beautiful cultivar with arching, green and gold striped leaves. New Zealand Flax usually sail through our coastal BC winters but benefit from a mulch of leaves at their base and having their foliage tied up to help it resist heavy snowfalls. In colder climates, grow in pots and bring indoors to a frost-free environment.
A vigorous cultivar with broad, arching leaves to 3' long and brilliantly colored yellow and green foliage. Another strong selection that forms dense clumps.
Arching 2-inch wide blades that have a central yellow band that is brighter when first emerging and fades to yellow-green by fall. Can tolerate fairly dry conditions (Coastal) but looks best with occasional to regular irrigation. Full sun to partial shade.
Variegated foliage. Eastern US native.
