Phormium 'Jack Spratt' is one of the smallest New Zealand Flax on the market, maturing to around 18 inches tall and wide. It has narrow, twisting, reddish-brown foliage. Plant in full sun to light shade. ‘Jack Spratt’ is a great plant for mass plantings, in the low border or small containers.
Prefers moist soil with good drainage. Water regularly after planting until roots are established then reduce frequency. Some drought tolerance, but better with occasional irrigation. Some Phormium hybrids are less tolerant of extreme temperatures and extended dry conditions. Provide light afternoon shade in hot inland valleys for cultivars with arching leaves to prevent sunburn. For a tidy appearance prune out old foliage at base. On colorful varieties, remove any foliage that may be reverting back to green or bronze.
