I have removed the seeds from the pod along with much of the pith that surrounds them but I do not attempt to remove the eliasome – the white fleshy appendage. I have read that some people believe that leaving the eliasome on can inhibit the germination of the seed but I have never found that to be the case.
Trillium seeds in leafmould
To further clean and prepare the seeds I have rubbed it in some of our own leafmould and this year I have decided to give it a period in the fridge. I have never bothered doing this before and I often have to wait two years for the seeds to appear above ground.
