@browncoat - I always thought that there was an easy enough solution for the fact that it's so difficult to pick saffron.
Just plant the bulbs in beds that have been raised to waist height.
I know this would cause initial expense, but if you made the beds really well, you'd just have to walk along and pick the stamens easily and quickly, without hunching down.
They like rocky soil, so they must need good drainage. Having raised beds would also help with this.
I don't have the land to try this, but if I ever did I would give it a shot. They are gorgeous flowers anyway, so it definitely wouldn't do any harm to have some rows of them in the garden.
