dahlias

[Mr List]

are all dahlias perenials?

i see a lot of cheap ones that are sold as little bedding plants last summer and i was wondering if i take them in will they come back next year?

i know my bishop of landaff are proper dahlias that will come back but i have no idea about fancy no name double bloom types that you get cheap in markets etc..

Yes they all continue growing year after year.

[Mr List]

oh good.

i wasnt sure as i dug up one i didnt want (and since it was going in the bin) i ripped it apart to look at what dahlia tubers are like.

it didnt have one so i thought to myself that might not have been a parennial

I thought folks were supposed to dig up the tubers and store them for winter?

I have some nice dahlias that I grew from seed this year. They are still all in flower and continuing to flower (although the gales have removed half!).

Can I just leave them in ground, let them die down and expect to see them again next spring?

Leave them to blacken by frost (foilage) then dry and store in dry compost or newspaper somewhere frost free.

Mine are also still in flower Bob.

The only thing with double headed flowers is that the flowers wont last as long as a single stemmed flower. This could be the reason why they get sold cheap.
