This Summer Dahlias

My dahlias began to bloom from the end of August and continue blooming so far. I was waiting for their flowers in mid-August but they bloomed later. Truly to say every autumn I think: 'I won't store Dahlias tubers anymore in the city apartment, as they get dried and die during storing'....
But when I see new Dahlia leaves I forget my doubts. So let's see their blooming this summer.

There are annual dahlias that are easy in growth. One can grow them from seed or buy seedlings in a garden center. This spring I did buy the seedlings because there were no space on the windowsills for more sowing :-) They were not expensive and it was mix of annual dahlias. Here they are:

Now in September, when many other flowers have disappeared, and the roses have almost finished their flowering, the dahlias adorn the garden, adding bright colors. I hope that they will blossom when the first frost or low temperature comes. 
Perhaps I would decide to keep Dahlia tubers. Or not? "To be or not to be is a question," as Shakespeare said. :-)
