I was lucky enough to get a packet of seeds in the Gardeners World dahlia
trials and have been very pleased with the results.
We received Thompson & Morgans Bishops Children mixed, and some of them are
truly magnificent, well worth repeating next year.
I was wondering about saving seed from particular favourites.
Does anyone know whether this variety is a F1 hybrid or will the seeds come
true to type ?
Best Regards

The chances are they will not come 'true to type'

However; you will probably find that most of them, if not all, will have formed tubers.

These can be stored till spring in a frost free place then cuttings can be taken in early spring.

This is the best way of ensuring you get a replica of the parent.

To save me a lot of typing you can have a look in to my website for further information.; http://thegardenersalmanac.co.uk/
