Since we felled the adjacent Eucalytpus tree (park-sized tree in suburban terraced garden.. didn’t work) the Phormium has gone ballistic. It flowered for the first time last year - 1 stem. This year there are 6 flower stems 9-10ft tall.
This pic might help in terms of choosing a location - it was 2 feet high and fairly narrow 3 years ago and as you can see it has shot both up and out in that time -
That’s really helpful, just pondering where to put one as it seams they don’t like un-sheltered spots and we are on clay so would need to sort drainage and mound it.
Also moved the purple fountain grass into the other corner as it seems it actually grows much bigger than I thought. At least now it will hide the BT internet box shite
