Sadly the chances of germination are not good with stored seed. P. vulgaris are fascinating things. There are two types of flower, pin eyed and thrum eyed. they are functionally monoecious! Basically that means that they have different sexes on different plants. The seed really needs to be sown even before it is ripe on the plant for good germination. You need to find a plant with a seed capsule which is almost ready to open, take out the still green seeds and sow immediately and wait for spring. The plant produces germination inhibitors in between the green stage and the capsule opening. By sowing green you bypass that stage.
If your seed does not germinate, give me a PM in a few weeks time and I will see if I can find you some seed.
Pity you do not live closer, you could come and weed some of them out of our lawn, flower beds, gravel garden,veg patch etc.!
