Has anyone on here tried growing the stuff from seed? I quite fancy getting a patch going in my garden.
Yes. It's very easy and within a couple of years they start to produce harvestable leaves and flowers.
Just gather the seed when ripe and sprinkle over your chosen patch right away. A word of caution it does freely seed and spread about the garden when it's established.
The seed should almost be ready for collecting, the pods will go from green to light brown and the little black seeds should easily fall out if you tap them.
