Andrewr's Garden
Phormium tenax
Genus: Phormium.
Species: Phormium tenax.
I have found two snags with this plant. Firstly, it gets a lot of dead foliage and really needs a good clearout at least once a year. Secondly, I found one of them was a snail hotel this year. One in the sunny front garden flowered every year; the other in not such a warm spot flowered for first time in 16 years in the hot summer of 2006 and the flower spike was 12 feet tall!
