14 years is stretching it a bit, they take about 7 years from seed and once they are established, the offsets will flower once the main bulb has finished, so giving a continuous display.
For me the ones at Dunham Massey were covered in Lily beetles and very badly damaged. Mind that was a couple of years ago, so they may have managed to keep the plants clean since then. Hope so.
