I sowed mine the following March (2016) and they germinated very well. 18 months on, they are about a foot high and doing well. I sowed some more of the seeds this March, but no luck - I assume they have to be reasonably fresh.
We gave our neighbour a division from the same phormium a couple of years ago & that now has a flower spike, so I'm going to have another go - I love a challenge
