Dahlias - do they all have tubers?

I bought three dahlias of the "Happy Days" series from B&Q in June as space fillers and they have been fantastic, growing to over 2' with masses of blooms. They still have lots of buds, but I need to dig them up to plant bulbs. The first plant has been removed and transferred to a pot, but it didn't have tubers, only roots. Is this a new annual form?

This one didn't get answered while the forum was sick but I know nothing about dahlias

Well Verdun, hopefully someone will be along shortly to answer that question!
I have been told by a supplier some done by cuttings in the spring may not develop tubers and have been bred to concentrate growth more into flowering. Not sure if this is correct though? I wonder whether the use of growth retardant could affect tubeer production? The ones we had to try have produced tubers though
What about Begonias?
Do these form Corms too from those bedding plants that you buy? ( I bought the Illumination variety)
If no-one knows I guess I'll find out come November :P
Illumination begonias are tuberous, they will die down to a large corm, which can be saved in a frostfree place and then regrown next year.
There are fibrous rooted(semperflorens) begonias used in bedding displays (small flowers), which will not form a tuber or corm.
Thanks fidgetbones
This will save me some money for next year
I don't like those bedding begonias anyway!
Dahlias grown from seed or cuttings do eventually grow tubers.
