About Phormium ‘Yellow Wave’ (New Zealand Flax ‘Yellow Wave’)
Prized for its foliage, this upright growing shrub is called Phormium ‘Yellow Wave’. Its sword-like foliage is yellow with lime green margins that grow upwards and eventually arch at the ends as the plant grows. Reaching an average mature landscape size of 3-4′ tall with a 4-5′ spread, its leaves can grow as wide as 1-3″. During the spring, tall spikes with tubular red flowers emerge but typically only in mature plants. This variety is part of the New Zealand Flax cultivar and known commonly as New Zealand Flax ‘ Yellow Wave’.
