Which berries...? Most you can, squeeze off as much of the flesh as you can with your fingers. Then wash as the seed in a bowl of tepid water to remove the rest. Blot dry on kitchen paper store the seed in a plastic bag filled with dry sand and keep it cool until sowing time.

I will certainly try this - thanks - the (red) berries are soft with a clear seed inside - they come from a very long thin conifer/type shrub.

That sounds like an Irish Yew. If so, the soft, red berry does not entirely cover the seed but holds in a cup-like manner? These should grow quite easily but it will take a long time to get decent sized plants. Still well worth trying.

Remember the berries are poisonous so wash your hands well after handling them

Bulbaholic - you have hit it on the head - the berries do indeed just cup the seeds - and now I know what it is.
I will certainly try - and if it takes time I will be patient. Thanks very much - Moon growe I will remember to wash my hands ! thanks to you too.

'Taxus baccata Fastigiata' if you want it's Sunday name, Sal.

And it is not a berry.....a berry has to have more than one seed. The yew berry is a highly modified female cone, and the term for it is an Aril...it will never catch on.
